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 V<sub>IHH</sub> (9V – 13.25V).
 +
*Standard ICSP
 +
**Use external programmer (e.g. MPLAB<sup>®</sup> ICD 2, MPLAB<sup>®</sup> PM3 or PRO MATE<sup>®</sup> 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.

 +
 
 +
===RTSP: COM Port (Bootloader)===
 +
*RTSP works in normal voltage (MCLR# no need to raise to V<sub>IHH</sub>).
 +
*No literature has mentioned the incorporation of Programming Executive (PE). Presumably, since Enhanced ICSP needs to set MCLR# to V<sub>IHH</sub>, RTSP cannot use PE.

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.

Software Interface

  • The program can be written and compiled in an Integrated Development Environment (IDE) using either Assembly or C. The complied codes are then loaded to the device through the external programmer.
Summary of IDE
Product Name Features OS Price (US$)
MPLAB® IDE Assembler Only Windows Free
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.
