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

  • 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.
    • Refer to Section 11 for programming in ICSP.
    • Program memory can be erased using Normal-Voltage (4.5 – 5.5V) or Low-Voltage (2.5V – 4.5V).
  • 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.
    • Refer to Section 8 for programming the PE.

  • 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.


Table 3.4 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 0.12.0 Assembler and C-Compiler Linux Free2
  1. Full-featured for the first 60 days. After 60 days only optimization level 1 can be enabled in the compiler. The compiler will continue to function after 60 days, but code size may increase.
  2. The current version supports external programmer ICD 2, but not yet tested.

RTSP

  • 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.
