A primary concern when setting the configuration bits for any application is the clock source. The example programs were written for a development board which does not have an external clock source for the MCU. As a result the configuration bits direct the PIC16LF1937 to use the internal RC oscillator combined with the 4x PLL as the clock source.

PIC serial communication tutorial Introduction to Serial communication with PIC16F877 microcontroller. The implementation of the PIC serial communication (C program and a video) We will show how to set USART in order to allow communication between PIC to PIC or between PIC to a personal computer. We will start with the definition of media. Aug 07, 2008  Serial communication with PIC chip. Arduino Forum > Forum 2005 -2010 (read only) > Hardware. I'm using the PIC16F690 that comes with the PICkit2 programmer/Low Pin Count demo board from Microchip. Here's my code written with the CCS C compiler for the midrange PIC devices: Code: // PIC code #include #fuses INTRC_IO, NOWDT.

No other configuration enabled features are needed by the example programs. Assembly Language For the example programs written in assembly language the configuration bits are coded in-line using the __CONFIG directive. To install the lab files simply unzip the downloaded file into any directory on your computer. The 'Getting Started' document in the downloaded project files shows how to install the compiler, MPLAB X IDE and Proteus.

Configuring the Demonstration Programs When installed, the labs files contain MPLAB X projects for each demonstration. The demo projects have all been configured to use MPLAB X IDE's internal simulator as the 'hardware tool' You have the option of selecting the F1 Evaluation board as the simulation tool. If running Windows you also have the option of selecting LabCenter's Proteus VSM as the simulator.

Changing the default settings can be done from the Project Properties Window for each of the projects.

In this tutorial, you will learn how to serially communicate a PC or any other device with a PIC microcontroller. You will also study the use of a communication component – UART (Universal Asynchronous Receiver Transmitter) present within the microcontroller. Serial vs Parallel Transfer Computers transfer data in two ways: serial and parallel. In serial Communication, only a single wire is required to transfer n bits of data or one or two wires for ready and acknowledge signals whereas in parallel communication, n wires are required to transfer n bits of data. Serial mode is used to transfer data to greater distances and parallel only works for short distances.

Since more hardware is required in parallel communication mode, hence, serial communication is preferred.In data Transmission, if data can both be transmitted and received, it is a duplex transmission. In contrast, a simplex transmission only sends data from one device to the other such as from computer to printer. Duplex Transmission can be Half or Full duplex depending upon whether the data transfer is simultaneous or not. If data is transmitted one way at a time, then it is half duplex.
