Serial communication was once the most widely used method of transferring data between computers. Many computing devices that you have used over time employ serial communication.

Some of the terms associated with this type of data transfer are FTDI chip, COM interface, the RS232 protocol, and serial port.

Serial communication refers to data that is electronically sent and received a single bit at a time. It forms the foundation of data transmission between personal computers. Its ease of use made it attractive to the early manufacturers of personal computers and peripheral devices.

There is a good chance that your laptop does not contain a serial port. They have been largely replaced in the consumer market by the faster interfaces and connections provided by the USB standard.

But serial communication is not dead yet. Many industrial and commercial processes rely on the simplicity and stability of serial communication.

Industrial automation systems are becoming more prevalent and are essential to the business processes of many diverse enterprises.

They operate with arrays of networked electronic devices that perform various functions in production facilities. These devices act as sensors and monitors that help control complex automated processes.

Many of the components of industrial automation systems rely on serial communication to interact with each other and the computers that control them.

They are designed with serial ports to facilitate their use in these automation systems. Serial applications are used to control the devices and their ability to communicate is vital to the operations of countless production lines around the world.

Embedded systems make use of serial communication in a number of ways

Some of the ways that embedded systems use serial communication are:

• Allowing different parts of a device to communicate with each other;
• Staying current by downloading firmware updates;
• Providing users a testing or debugging interface;
• Communicating with external devices.

Developers and software engineers who are tasked with implementing serial communication in embedded devices must rely on their knowledge of the protocols that form the backbone of this data transmission method.

There are many serial protocols in use, but the RS232/RS422/RS485 standards are the ones most commonly used.

You will find these protocols used extensively in industrial automation and embedded systems which make use of serial communication.

Through the use of devices like USB to serial converters, computers that do not possess a serial port can still communicate with serial devices.

There are several advantages that serial communication offers over alternative technologies such as Ethernet, USB or WiFi. While these other options may provide higher connection speed, they are not as easy to implement as serial technology.

The majority of operating systems include built-in support for serial ports and the interfaces do not need to have custom drivers installed.

The absence of serial ports on the current generation of laptops can be an impediment to developers who need to interact with serial devices and applications.

It definitely hinders their development efforts and makes it difficult to test and troubleshoot their products. But there are hardware and software solutions that can help get around the port limitations of any Windows computer.

There are simple hardware devices that can be used to translate between USB and serial signals. These devices are easy to use and involve connecting one end of the converter to the USB interface on your laptop.

The other end of the converter is a serial interface which can be used to connect to a serial peripheral device. That device can now operate with your laptop in the same way as if it was equipped with serial ports.

A more effective solution to the lack of serial interfaces is to employ software that can create virtual serial ports which behave as if they were actual physical interfaces.

This eliminates the need for additional hardware and its associated cabling.

Here are two versions of a software tool that provide the user with the ability to create virtual serial ports. Serial hardware and software developers and testers will find these tools to be indispensable.

The same can be said for users working with embedded devices employing serial communication.

Virtual Serial Ports make it possible for computers that do not have any physical serial ports to interact with serial devices.

Virtual COM ports work by sending and receiving data over a network instead of through a cabled connection with the peripheral equipment.

This is accomplished by configuring the computer using specialized software. An excellent choice for creating virtual ports is Virtual Serial Port Driver (VSPD) from Eltima Software.

This communication software facilitates the creation of an unlimited number of virtual serial ports. The virtual ports can be connected via a virtual null-modem cable. Every virtual interface that you create totally emulates the functionality of a physical port.

VSPD makes it easy to create and manage your virtual ports and extend the utility of your serial devices. Using the software allows any machine to access network-connected serial devices despite the lack of physical interfaces.

Now you can take full advantage of serial devices even if you are located on the other side of the world from them.

VSPD is available in Standard and Pro versions and you can test drive both products with a 14-day trial.

Input devices play a vital role in any electronics projects. These input device help the user to interact with the digital world. An input device can be as simple as a push button or as complicated as a touch screen; it varies based on the requirement of the project. In this tutorial we are going to learn how to interface a joystick with our PIC microcontroller, a joystick is a cool way to interact with the digital world and almost everyone would have used one for playing video games in their adolescence age.

//*****I/O Configuration****//
TRISC=0X00; //PORT C is used as output ports
PORTC=0X00; //MAke all pins low
TRISB0=1; //RB0 is used as input
//***End of I/O configuration**///

ADC_Initialize(); //Configure the ADC module

    int joy_X = (ADC_Read(0)); //Read the X-Axis of joystick
    int joy_Y = (ADC_Read(1)); //Read the Y-Axis of Joystick

    if (joy_X < 200) //Joy moved up
    {RC0=0; RC1=1;} //Glow upper LED
    else if (joy_X > 800) //Joy moved down
    {RC0=1; RC1=0;} //Glow Lower LED
    else //If not moved
    {RC0=0; RC1=0;} //Turn off both led

    if (joy_Y < 200) //Joy moved Left
    {RC2=0; RC3=1;} //Glow left LED
    else if (joy_Y > 800) //Joy moved Right
    {RC2=1; RC3=0;} //Glow Right LED
    else //If not moved
    {RC2=0; RC3=0;} //Turn off both LED

    if (RB0==1) //If Joy is pressed
        RC4=1; //Glow middle LED
    else
        RC4=0; //OFF middle LED

GPS is the short-form of Global Positioning System. It is a system which provide accurate Altitude, Latitude, Longitude, UTC time and many more information, which are taken from 2, 3, 4 or more satellite. To read data from GPS, we need some Microcontroller and we already interfaced GPS with Arduino and with Raspberry Pi.

We have selected G7020 GPS module which is made by U-blox. We will receive Longitude and latitude of a particular position from satellite and will display the same on a 16×2 Character LCD. So here we will interface GPS with PIC16F877A microcontroller by microchip.

For any project to come alive, we need to use sensors. Sensors acts as the eyes and ears for all embedded application, it helps the digital Microcontroller to understand what is actually happening in this real Analog world. In this tutorial we will be learning how to Interface Ultrasonic Sensor HC-SR04 with PIC microcontroller.

The HC-SR04 is an ultrasonic sensor which can be used to measure distance anywhere between 2cm to 450cm (theoretically). This sensor has proved itself worthy by fitting into many projects which involves obstacles detection, distance measuring, environment mapping etc. At the end of this article you will learn how this sensor works and how to interface it with PIC16F877A microcontroller to measure the distance and display it on the LCD screen. Sounds interesting right!! So let’s get started…

Materials Required:

1. PIC16F877A MCU with programming set-up
2. LCD 16*2 display
3. Ultrasonic sensor (HC-SR04)
4. Connecting wires

How does an Ultrasonic Sensor work?

Before we get any further, we should know how an Ultrasonic sensor works so that we can understand this tutorial much better. The ultrasonic sensor used in this project is shown below.

Distance = Speed × Time

  TRISD = 0x00; //PORTD declared as output for interfacing LCD
    TRISB0 = 1;        //Define the RB0 pin as input to use as interrupt pin
    TRISB1 = 0; //Trigger pin of US sensor is sent as output pin
    TRISB2 = 1; //Echo pin of US sensor is set as input pin      
    TRISB3 = 0; //RB3 is output pin for LED
    T1CON=0x20; //4 pres-scalar and internal clock

        Trigger = 1;
        __delay_us(10);          
        Trigger = 0;

        while (Echo==0);
            TMR1ON = 1;
        while (Echo==1);
            TMR1ON = 0;

time_taken = (TMR1L | (TMR1H<<8));

Time = (16-bit register value) * (1/Internal Clock) * (Pre-scale)
Internal Clock = Fosc/4

Where in our case,
Fosc = 20000000Mhz and Pre-scale = 4

Hence the value of Internal Clock will be 5000000Mhz and the value of time will be

Time = (16-bit register value) * (1/5000000) * (4)
          = (16-bit register value) * (4/5000000)
          = (16-bit register value) * 0.0000008 seconds (OR)
Time = (16-bit register value) * 0.8 micro seconds

time_taken = time_taken * 0.8;

Distance = (Speed*Time)/2
                = (34000 * (16-bit register value) * 0.0000008) /2
Distance = (0.0272 * 16-bit register value)/2

distance= (0.0272*time_taken)/2;

Hi All You Guys.

How long have you been working on CCS C. CCS will be able to see my level, so it is no longer something to do after arrival.

In this article, I made a small application on the USB communication pic18f4550. I really wanted to deal with the USB. A little uğraştırsada due to the short time for plenty of sample applications around USB thing figured out. I think there’s a common idea in dealing with USB. Because that I haven’t read about this article or the article. Well, first a couple of application korkutsada the USB after the eye really is different from rs232 communication in terms of convenience.

Now, my application

The system is very simple. Depending on the temperature the temperature sensor DS1820 Sıcaklık Sensorü RA5 pic18f4550, PIN information, and sends it to the computer via the USB port. For now only sends to the computer. I’m a little more for the novice yet C # form and showed the form only in order to show the temperature of the communication with the pic.

Note: the Fan control circuit used in standard pc vaults can be connected to the cpu fans or oğutucu fans (100-250ma)

The Intelligent Fan Controller is designed to control the noise generated by the fans inside your computer. It does this by varying their speed based on temperatures measured inside the case. When it is cool the fans will run slowly and they will only speed up when needed… when your computer is running hot.

Anyone with a noisy computer, especially a Media Centre system in the lounge room, will benefit from this project. After installing this device, my computer is now so quiet that I can hardly tell that it is running – and that is a blessed relief.

The main features are:

Configurable speed control based on temperatures measured inside your computer
Control up to eight fans and measure up to four temperatures
USB interface and Windows software for setup and monitoring
It will run independently without the Windows software (once it has been configured)

Recently i was working with 8-bit pic16f877 microcontroller and i want to place program code at a specific rom(read only memory) location. I was working with xc8 compiler and mplabx ide.  Previously i did this same thing many times while using c18 c compiler. C18 compiler uses #pragma code directives to accomplish this task. But when i started with xc8 compiler and put the same #pragma code directive in my code the compiler starts giving errors. I found that the xc8 didn’t support #pragma code directives. So now i have to locate the xc8 macros for accomplishing this task. I searched the internet but did not found any major help regarding it. Then i decided to read the xc8 compiler datasheet. After lot of reading i found some valuable information and now i want to share it with the microcontroller projects community.

I found three methods to store data at a particular location in program memory of pic microcontroller, when working with xc8 compiler. The three macros/directives that i found were

• __section()
• __at()
• ‘@’ qualifier​

The first two methods are little complex and difficult to manage, while the third one the ‘@’ qualifier is easy to manage and use. Before using the ‘@’ qualifier one should first check the program memory banks addresses range of the pic microcontroller that he is using. I am using pic16f877 microcontroller, its program memory address range is from 0x0000 to 0x1FFF. The word size is 14 bits and memory size is 8 KB. 

I want my code to start at program memory location/address 0x200. To do so i placed the ‘@’ qualifier at the end of the main function. See the above main function initialization. At the end of the closing brackets i placed the @ qualifier with the program memory address where i want my code to be placed in flash/rom. In the main function i have two for loop functions, generating a random delay.    

int main(int argc, char** argv) @ 0x200 {}

USB REMOTE CONTROL SERVER

When you first run this program if the USB device is not connected to your PC, the program does not make a configuration for connection to a USB device to connect and begin to listen. USB Devices plugged into a PC Server software will detect it and as soon as the connection between the USB device and plug açar.ayn time bağlantısını configure the program and get to listen on port 8090. When a connection arrives, and it accepts commands from the client program that provided the link starts to wait. Normally 4 bytes of data are moved between Server and Client. It is thought the four bytes in the command structure is as follows;

unsigned char CmdBuffer[4];

CmdBuffer[0] = Aygıt İndex'i (Örneğin 0 - 0.Cihaz, 1 - 1.Cihaz gibi)
CmdBuffer[1] = Aygıt On/Off (Örneğin 1 ise aç, 0 ise kapat gibi)

Client Server program from the program before it receives a command structure above the screen writer then sends pıcmicro. Pıcmicro selected from the relay connected to PORTB evaluating these structures are shut or open.

COM terminal allows you to send and receive serial data on the serial interface of the PC RS232. Adjustable serial ports are COM1, COM2, COM3, COM4. All possible baud rates, parity, number of bits can be set. The serial port settings are saved in an ini file. For new start the terminal program, previous settings are effective.

Unlike other terminal programs: To send any-way 8-bit word by serial port. As input characters (A), the number (0 .. 255), or binary (00001111). -Received data will be output in three formats. -It is a condition of wires DSD, CTS, DSR displayed (black is 0, red is 1). Control lines DTR, RTS are switchable. -A range of characters can be transmitted, wherein the time between sending each character can be set in ms.

COM TERMINAL PROGRAM

Than 8 switch outputs Port B of the PIC18F2550 is used. Power gets the circuit from the USB port. Power supply is separate from the microcontroller and the computer galvanically. switching signals USB socket intended as a virtual serial port COM4. To turn on the first load, send “E1” to turn off “A1” This can be done with any terminal program. Or even easier with a BAT file. ECHO E3> COM4 This turn of the third load.

If you use a triac to the heat sink, consumers can receive up to 10A (2300W). Without heat sink enables you to weigh up to 100 watts. E.G. a lamp. Note the heat sink under voltage (230V) is available. In addition, here is single-pole disconnection. That means current is switched off, voltage remains. Pull for repairs to the consumer mains.

Addendum. I’m reinventing the wheel completely stupid second time. When it accumulates give beautiful solid-state relay. E.G. S202 S02 (current to 8A with the heat sink) Resistance calculation for connection to 5V (5V-2, 2V) / 8mA = 350ohm Minus the mass. Plus over 330 ohm resistor to pin PBx.

PICKit2 is a USB powered device, that is it gets power from PC USB +5V power supply. USB microcontroller PIC18F2550 is the soul of the PICKit2. The USB Data+ and Data- from PC are connected to the D+ and D- pins of the PIC182550. The built-in-clock generator of pic uses external crystal oscillator X1, C2 and C3 to ensure the correct system clock rate. The inductor L1, MOSFET Q1, diode D1, capacitors C1 and C4 forms a DC-DC converter (Buck Converter) which converts 5V from PC to 12V, which to be applied to MCLR/VPP pin of a microcontroller at the time of programming. This is controlled by the PIC firmware. The resistors R2 and R3 forms a voltage sensing feedback network, which is given to the analog pin AN0 of the PIC. MOSFET’s Q4, Q5 and resistor R5 are used for switching Vpp to MCLR/Vpp output. The MOSFET Q6 and resistor R4 ground the MCLR output whenever required. The MOSFET Q3 and resistor R16 are for switching Vdd to output whenever required. The Vdd sensing feedback is given to the analog pin AN1 of the PIC via resistor R6. The MOSFET Q2 with resistors R1, R17 provides active pull down to Vdd output whenever required. The diode D2 protects the circuit from external Vdd.

The LED1 with current limiting resistor R12 indicates that the circuit is powered form USB. The LED2 along with current limiting resistor R11 indicates that Vdd is switched to output. The LED3 with current limiting resistor R10 is controlled by the PIC firmware, normally glows during read and write operations indicating busy states.
The resistors R7, R8 and R9 are current limiting resistors in series with output lines PGD, PGC and AUX. The resistors R14 and R15 ensures active low at PGD and PGC outputs in certain cases.

Step 1: Substitutes for Unavailable Components

Components that I used in my clone are shown as bold.
The protection diode D2, BAT85 will drop much more voltage on Vdd. So if you wish to avoid the voltage drop you can short it. If you don’t want to completely eliminate the protection you can replace BAT85 with lower drop Schottky diode. Thus you can replace it with 1N5819 or 1N5818.You can replace the MOSFET Q3 (IRF9Z34) with cheaper BC640, in this case the output current will be limited to few hundred milliamperes with an acceptable voltage drop. You can also replace IRF9Z34 with IRF9540N if it is not available in your city.Inductor L1 can vary between 470uH – 1mH and should atleast 150mA rated. BS170 can be substituted by VN2010L or BS107BS250 can be substituted by VP2020L or BSS92 (be careful, BSS92 has different pinout!) or BC 557 with base resistor 1KYou can omit the 330nF capacitor. I used .1mF capacitor.Components that I used in my clone is shown as bold.
