Readme File for Code Example: 3-wire UART ---------------------------------------------- This file contains the following sections: 1. Code Example Description 2. Folder Contents 3. Suggested Development Resources 4. Reconfiguring the project for a different PIC24F device 5. Revision History 1. Description: --------------- This code example is a basic UART communication on RS-232 on Explorer 16 development board. Baudrate 9600, 8-bit data, No parity, 1 Stop bit, No Flow Control. It's a small, bare bones program to guide designers with UART implementation To run the program, plug DB9 cable to Terminal (9600,8,N,1) - Data sent from TERMINAL will be represented as binary equivalent of ASCII on 7 LSB LEDs of Explorer 16 development board Data is sent from Explorer 16 by pressing S3 - S6. A single letter will be transmitted upon each keypress. Peripheral Library was not utilized, Bit Addressing was used in order to show all details involved in initialization of UART. This code example has been tested on Explorer 16 Development Board with PIC24FJ128GA010, PIC24FJ256GA110 and PIC24FJ256GB110 PIMs. 2. Folder Contents: ------------------- This folder contains the following sub-folders: a. C:\Program Files\Microchip\MPLAB C30\support\gld This folder will have the device GLD file, it is used for building the project. This file was provided with the MPLAB?C30 toolsuite. b. C:\Program Files\Microchip\MPLAB C30\support\h This folder contains C header files useful in building this project. Device register and bit definitions are provided in the *.h file that follows the device name. These files were provided with the MPLAB?C30 toolsuite. c. C:\Program Files\Microchip\MPLAB C30\lib This folder contains library archive files, which are a collection of precompiled object files. The file named "libpic30-coff.a" contains the C run-time start-up library. These file were provided with the MPLAB?C30 toolsuite. d. hex This folder contains three file types - coff, hex and map. These are files generated by the MPLAB?C30 toolsuite on build operation performed within MPLAB?IDE. The *.map file contains details on memory allocation for various variables, constants and dsPIC instructions specified in the source and library code. The *.hex file contains a binary file that may be programmed into the dsPIC device. The *.coff file contains a binary file that is used by MPLAB?IDE for simulation. e. h This folder contains include files for the code example. f. src This folder contains all the C and Assembler source files (*.c, *.s) used in demonstrating the described example. This folder also contains a sub-folder named "obj" that stores compiled object files generated when the project is built. 3. Suggested Development Resources: ----------------------------------- a. Explorer 16 Demo board with one of the following MCU PIM PIC24FJ128GA010 or PIC24FJ256GA110 or PIC24FJ256GB110 4. Reconfiguring the project for a different PIC24F device: ------------------------------------------------------------- The Project/Workspace can be easily reconfigured for any PIC24F device. Please use the following general guidelines: a. Change device selection within MPLAB?IDE to a PIC24F device of your choice by using the following menu option: MPLAB IDE>>Configure>>Select Device b. Provide the correct device linker script and header file for your device. Device linker scripts and header files are available in your MPLAB?C30 installation folder under: Device Linker Script- YourDrive:>Program Files\Microchip\MPLAB C30\support\gld Device C Header file- YourDrive:>Program Files\Microchip\MPLAB C30\support\h Device ASM Include file- YourDrive:>Program Files\Microchip\MPLAB C30\support\inc c. Provide the appropriate path to your MPLAB C30 support file locations using the menu option: MPLAB IDE>>Project>>Build Options>>Project d. Re-build the MPLAB?project using the menu option: MPLAB IDE>>Project>>Build All e. Download the hex file into the device and run. 5.
