Readme File for Code Example: CE017 - Reading, Erasing and Writing to dsPIC30F Data EEPROM ------------------------------------------------------------- This file contains the following sections: 1. Code Example Description 2. Folder Contents 3. Suggested Development Resources 4. Reconfiguring the project for a different dsPIC30F device 5. Revision History 1. Code Example Description ----------------------------- Many dsPIC30F devices in the dsPIC Digital Signal Controller products feature internal or on-chip Data EEPROM (Electrically Erasable Programmable Read Only memory). This example provides C-callable, routines to read, erase or write one word or one row of internal Data EEPROM in dsPIC30F devices. The source file containing the functions is "DataEEPROM.s". The C header file describing the function prototypes contained in this file is "DataEEPROM.h". The code example also demonstrates the use of these routines in the "main_DataEEPROM_access.c" file. To use these functions simply, add the function prototypes (file DataEEPROM.h) and the function definitions (file DataEEPROM.s) to your project. ReadEErow prototype: -------------------- extern int ReadEE(int Page, int Offset, int* DataOut, int Size); Parameters Definition: Page: is the 8 most significant bits of the source address in EEPROM Offset: is 16 least significant bits of the source address in EEPROM DataOut: is the 16-bit address of the destination RAM location or array Size: is the number of words to read from EEPROM and is a value of 1 or 16 Return Value: Function returns ERROREE (or -1) if Size is invalid EraseEErow prototype: --------------------- extern int EraseEE(int Page, int Offset, int Size); Parameters Definition: Page: is the 8 most significant bits of the address in EEPROM to be erased Offset: is 16 least significant bits of the address in EEPROM to be erased Size: is the number of words to read from EEPROM and is a value of 1, 16 or 0xFFFF (for erasing ALL EEPROM memory) Return Value: Function returns ERROREE (or -1) if Size is invalid WriteEErow prototype: --------------------- extern int WriteEE(int* DataIn, int Page, int Offset, int Size); Parameters Definition: Page: is the 8 most significant bits of the destination address in EEPROM Offset: is 16 least significant bits of the destination address in EEPROM DataIn: is the 16-bit address of the source RAM location or array Size: is the number of words to read from EEPROM and is a value of 1 or 16 Return Value: Function returns ERROREE (or -1) if Size is invalid 2. Folder Contents: ------------------- This folder contains the following sub-folders: a. gld This folder contains the linker script file for the example project. This file is used for building the project. This file was provided with the MPLAB C30 v1.33 toolsuite. b. 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 v1.33 toolsuite. c. 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 dsPIC30F instructions specified in the source and library code. The *.hex file contains a binary file that may be programmed into the dsPIC30F device. The *.coff file contains a binary file that is used by MPLAB IDE for simulation. d. inc This folder contains Assembler include files useful in building this project. Device register and bit definitions are provided in the *.inc file that follows the device name. These files were provided with the MPLAB C30 v1.33 toolsuite. e. 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 v1.33 toolsuite. 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. MPLAB IDE v7.22 or later b. MPLAB C30 v1.33 or later c. MPLAB ICD 2 R23 or later d. dsPICDEM 1.1 Development Board (See below) e. dsPIC30F6014A Digital Signal Controller Plug-In Module (See below) 4. Reconfiguring the project for a different dsPIC30F device: ------------------------------------------------------------- The Project/Workspace can be easily reconfigured for any dsPIC30F device. Please use the following general guidelines: a. Change device selection within MPLAB IDE to a dsPIC30F 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. Chose the development board applicable to your device. Some options are provided below: - dsPICDEM 2 Development Board supports: 30F2010, 30F2011, 30F2012, 30F3010, 30F3011, 30F3012, 30F3013, 30F3014, 30F4011, 30F4012, 30F4013 - dsPICDEM 1.1 Development Board supports: 30F5013, 30F6010, 30F6011, 30F6012, 30F6013, 30F6014, 30F6011A, 30F6012A, 30F6013A, 30F6014A - dsPICDEM MC1 Development Board supports: 30F6010, 30F6010A, 30F5016 e. Re-build the MPLAB project using the menu option: MPLAB IDE>>Project>>Build All f. Download the hex file into the device and run. 5. Revision History : --------------------- 11/02/2005 - Initial Release of the Code Example
