Readme File for Code Example: I2C MASTER ----------------------------------------------------------------------------------------- This file contains the following sections: 1. Code Example Description 2. Folder Contents 3. Suggested Development Resources 4. Reconfiguring the project for a different PIC18F device 5. Revision History NOTE: The example code makes use of Peripheral Library support available with MCC18. 1. Code Example Description: ---------------------------- In this code example, I2C module in PIC18F4685 is configured as Master. Device communicates with another device using I2C portocol using SDAx & SCLx pins. *Connections: * I2C (MASTER) I2C (SLAVE) * (Another Device) * SCLx <-------------------------> SCLx * SDAx <-------------------------> SDAx 2. Folder Contents: ------------------- This folder refers the following sub-folders: a. C:\MCC18\bin\LKR This folder will have the device LKR file, it is used for building the project. This file was provided with the MCC18 toolsuite. b. C:\MCC18\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 MCC18 toolsuite.The peripheral library header files contains the macro definition & API prototypes. c. C:\MCC18\lib This folder contains library archive files, which are a collection of precompiled object files. The file named "*.lib" in the name of device contains the C run-time, start-up & Peripheral library. These file were provided with the MCC18 toolsuite. d. C:\MCC18\src This folder contains all the C ,Assembler, Peripheral library source files (*.c, *.s) used in demonstrating the described example. e. C:\MCC18\doc This folder contains the Peripheral Library description for all modules. 3. Suggested Development Resources: ----------------------------------- a. MPLAB IDE with MCC18 v3.30 or above b. PIC DEM 2+ Development Board with PIC18F4685 controller 4. Reconfiguring the project for a different PIC18F device: ------------------------------------------------------------- The Project/Workspace can be easily reconfigured for any PIC18F device. Please use the following general guidelines: a. Change device selection within MPLAB?IDE to a PIC18F device of your choice by using the following menu option: MPLAB IDE>>Configure>>Select Device b. To configure the device settings, either choose from the MPLAB IDE>>Configure>>"Configuration bits" and configure for necessary settings or the corresponding configuration macros to be added into the code can be obtained from device.INC file at the following default location: "C:\MCC18\mpasm" These macros can be added as depicted in example code. c. Re-build the MPLAB?project using the menu option: MPLAB IDE>>Project>>Build All d. Download the hex file into the device and run. 5.
