Readme File for Code Example:
CE103 - CPU In DOZE MODE
----------------------------------------
This file contains the following sections:
1. Code Example Description
2. Folder Contents
3. Suggested Development Resources
4. Reconfiguring the project for a different PIC24H device
5. Revision History
1. Code Example Description:
----------------------------
In this example, CPU is setup in DOZE mode to run at 1/128 of the System Clock.
Device is initially configured to run at Fcy=40Mhz and then DOZE mode is enabled to run the CPU at 312.5Khz (40M/128).
extern void setDozeRatio(unsigned int r);
This function sets the required DOZE ratio and enables the DOZE mode
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 v2.02 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 v2.02 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 v2.02 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. MPLAB IDE v7.31.01 or later
b. MPLAB C30 v2.02 or later
c. MPLAB ICD 2 R23 or later
e. Explorer 16 Demo board with PIC24HJ256GP610 controller
4. Reconfiguring the project for a different PIC24H device:
-------------------------------------------------------------
The Project/Workspace can be easily reconfigured for any PIC24H device.
Please use the following general guidelines:
a. Change device selection within MPLAB IDE to a PIC24H 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:
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 :
---------------------
