Readme File for Code Example: POWER MANAGEMENT ----------------------------------------------------------------------------------------- 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 NOTE: The example code makes use of Peripheral Library support available with MPLAB_C30 v3.11. 1. Code Example Description: ---------------------------- In this code example, POWER MANAGEMENT in PIC24FJ256GB110 is used to configure device operate on particular source of clock. The device is put to SLEEP and IDLE modes. The RESET sources and IDLE/SLEEP states are checked and corresponding response using LED is given to user. Below table shows the LED output for various RESET and SLEEP/IDLE states. * LED Indication Source of RESET * * 1 blink ------------> Power on RESET * 2 blinks ------------> brown out * 3 blinks ------------> watchdog timer time out * 4 blinks ------------> software reset * 5 blinks ------------> external reset (MCLR) * 6 blinks ------------> configuration word mismatch * 7 blinks ------------> illegal instruction execution * 8 blinks ------------> trap * * Continous On ----------> Wake Up from Sleep * Continous Off ---------> Wake Up from IDLE 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 & Peripheral library. These file were provided with the MPLAB?C30 toolsuite. d. C:\Program Files\Microchip\MPLAB C30\src This folder contains all the C ,Assembler, Peripheral library 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. e. C:\Program Files\Microchip\MPLAB C30\src\peripheral_24F\include This folder contains the header files for all Peripheral library support. f. C:\Program Files\Microchip\MPLAB C30\docs\periph_lib\Microchip PIC24F Peripheral Library.chm This file contains the Peripheral Library description for all devices and modules. 3. Suggested Development Resources: ----------------------------------- a. MPLAB IDE with MPLAB C30 v3.11 or above b. Explorer 16 Development Board with PIC24FJ256GB110 controller 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 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. 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:\Program Files\Microchip\MPLAB C30\support\PIC24F\inc" 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. Revision History : --------------------- 04/04/2009 - Initial Release of the Code Example
