This project aims to provide the development tools for building a multi-purpose MCU board. It was initially based on Microchip dsPic30F5011 and was later ported to dsPic33FJ128GP306 and dsPic33FJ256GP506. Despite the specific implementation on these platforms, information provided in this wiki may give useful directions for developing similar embedded systems with different platforms

This project aims to provide the development tools for building a [[Multi-purpose_Embedded_System | multi-purpose MCU board]]. Description is based on Microchip dsPic33FJ256GP506 (was dsPic30F5011), but information provided in this wiki may give useful directions for developing similar embedded systems with different platforms.

Programming Methods

  • There are 2 programming methods: In-Circuit Serial Programming (ICSP) and Run-Time Self-Programming (RTSP)
  • ICSP allows the devices to be programmed after being placed in a circuit board.
  • RTSP allows the devices to be programmed when an embedded program is already in operation.

ICSP: External Programmer (ICD2)

  • Two types of ICSP are available: ICSP and Enhanced ICSP. Both of them require setting MCLR# to VIHH (9V – 13.25V).
  • Standard ICSP
    • Use external programmer (e.g. MPLAB® ICD 2, MPLAB® PM3 or PRO MATE® II) only.
    • Required low-level programming to erase, program and verify the chip.
    • Slower, because codes are serially executed.
  • Enhanced ICSP
    • Use external programmer and Programming Executive (PE).
    • PE is stored in the on-chip memory.
    • PE allows faster programming.
    • PE can be downloaded to the chip by external programmer using the standard ICSP method.
    • PE contains a small command set to erase, program and verify the chip, avoiding the need of low-level programming.

MPLAB® C30 Assembler and C-Compiler Windows $895.00 (Free student version1)
Piklab Assembler and C-Compiler Linux Free
  1. Full-featured for the first 60 days. After 60 days, some code optimization functions are disabled. The compiler will continue to function after 60 days, but code size may increase.

RTSP: COM Port (Bootloader)

  • RTSP works in normal voltage (MCLR# no need to raise to VIHH).
  • No literature has mentioned the incorporation of Programming Executive (PE). Presumably, since Enhanced ICSP needs to set MCLR# to VIHH, RTSP cannot use PE.
  • Refer to bootloader section.

  • C-Compiler, Assembler and Linker are under GNU license.
    • MPLAB C30 C Compiler (*.c -> *.s)
    • MPLAB ASM30 Assembler (*.s -> *.o)
    • MPLAB LINK30 Linker (*.o -> *.bin)
  • PA optimizer, simulator, runtime libraries, header files, include files, and linker scripts are not covered by GNU. Reference is here.
  • Microchip has integrated ASM30, LINK30, assembly header files, linker scripts in MPLAB IDE, which is free for download.
  • MPLAB C30 costs US$895. A 60-day free student version is also available. After 60-days, the optimizer is automatically disabled, while other tools can still function properly.

Burning Program Codes to Target Board

  1. Use 'dspicprg and dspicdmp' utilities developed by Homer Reid to burn hex code (*.hex) to devices. See Reference here. Through serial port only?
  2. Use Piklab IDE. Details on file format not known.
  3. Use MPLAB IDE to burn hex code (*.hex) to devices.

Code Optimization

  • Below is a comparsion between different optimization levels for the project including drivers for 2 projects.
Comparison between differnt optimization levels
Optimization Description Project 1
Code Size

Project 1
Data Usage
(byte)
Project 2
Code Size
(byte)
Project 2
Data Usage
(byte)
O0 No optimization
Fastest Compilation
6222 (9%) 178 (4%) 26,037 (38%) 710 (17%)
O1 Optimize
Tries to reduce code size and execution time.
4473 (6%) 178 (4%) 22,290 (32%) 710 (17%)
O2 Optimize even more
Performs nearly all supported optimizations
that do not involve a space-speed trade-off.
Increases both compilation time and the
performance of the generated code.
4422 (6%) 178 (4%) 21,993 (32%) 710 (17%)
O3 Optimize yet more.
O3 turns on all optimizations specified by O2
and also turns on the inline-functions option.
4485 (6%) 178 (4%) 22,176 (32%) 710 (17%)
Os Optimize for size.
Os enables all O2 optimizations that do not
typically increase code size. It also performs
further optimizations designed to reduce code
size.
