Code Examples


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.
    • 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.

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 2.4 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, some code optimization functions are disabled. 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: 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.

  • Software Drivers are to be developed to allow users at Application Level to use the hardware (e.g. ADC, DAC, UART, EEPROM etc) through the OS.
  • The interface between the drivers and the OS is based on POSIX standard (e.g. open(), write(), read(), ioctl(), usleep() etc).
  • The most up-to-date development can be found at repository freertos_posix

USB-RS232 Bridge

  • As USB ports are becoming more and more common, COM ports and Parallel ports may be redundant in the next few years. This section explore the possibilities of programming the target board through a USB port.
  • There are two options:
  1. Use an external USB/RS232 adaptor, the driver will emulate a virtual COM port, such as Prolific and FDTI. Ingenia has tested its bootloader with some USB-232 manufacturers (silabs, FTDI, etc..). However, the programming failed with our Prolific adapter. Application program may use JavaComm API (javax.comm) and/or RXTX to drive the COM port.
  2. Modified the bootloader program on PC to support USB communication. e.g. using jUSB and JSR-80 (javax.usb). External circuits such as PIC18F4550 and MAX232 are required.
   |--User's App.--|-------Device Manager------|-------USB-RS232 Interface------|---dsPIC---|
  Option 1:
    +-------------+  +----------+  +----------+  +---+  +------------+  +-----+  +--------+
    | Application |--| JavaComm |--| Virtual  |==|USB|--|    FDTI    |--|RS232|==| Target |
    |   Program   |  |  RXTX    |  | COM Port |  +---+  | Circuitary |  +-----+  | Board  |
    +-------------+  +----------+  +----------+         +------------+           +--------+
  Option 2:
    +-------------+          +--------+          +---+  +------------+  +-----+  +--------+
    | Application |----------| JSR-80 |==========|USB|--| PIC18F4550 |--|RS232|==| Target |
    |   Program   |          |  jUSB  |          +---+  |   MAX232   |  +-----+  | Board  |
    +-------------+          +--------+                 +------------+           +--------+
  • Currently, when RXTX is incorporated with JavaComm API, operating systems supported include Linux, Windows, Mac OS, Solaris and other operating systems. On the other hand, jUSB and JSR-80 only works for linux.

FDTI Chipset

  • FT232RL communicates with PC via USB to provide 1 UART channel.
  • Datasheet can be downloaded here.
    • Refer to Fig. 11 (Page 19) for Bus Powered Configuration.
    • Refer to Fig. 16 (Page 24) for for UART TTL-level Receive [RXD -> 1], Transmit [TXD -> 4], Transmit Enable [CBUS2/TXDEN -> 3]. Omit Receive Enable [CBUS3/PWREN#] and use [CBUS2/TXDEN -> 2]
    • Refer to Fig. 15 (Page 23) for LED Configuration: [CBUS0/TXLED#] and [CBUS1/RXLED#]
  • Virtual COM Port Drivers can be downloaded here.


Programming the Device

  • Description on how to use dsPicProgrammer to download firmware to dspic


Remote Access

  • At the moment, local devices (e.g. EEPROM, ADC, DAC, etc.) can only be accessed locally through POSIX functions such as open(), read(), write(), ioctl().
  • However, a client may need to access these devices on a remote server. This section reviews the background and gives some ideas on its possible implementation.

Requirements

  • A remote file access protocol, to transfer "files" (i.e. device's data) such as:
  1. File Transfer Protocol (FTP): Required files are copied from sever to client for manipulation
  2. Remote Shell (RSH): Required files are copied from sever to client for manipulation
  3. Network File System (NFS): Required files are manipulated on sever
  • An API to access files using a selected protocol, such as:
  1. lam_rfposix: A POSIX-like remote file service for Local Area Multicomputer
  2. API employed by VxWorks: VxWorks is a Unix-like real-time operating system, commonly used for embedded systems.

API Reference for VxWorks


Conversion to dsPIC33F Devices

  • This section discusses the conversion required from dsPIC30F5011 to dsPIC33FJ128GP306.
  • Refer to official document dsPIC30F to dsPIC33F Conversion Guidelines (DS70172A).
  • Note that this section does not mainly intend to introduce the new functionalities of dsPIC33F devices. It only serves the purpose to summarise the major (if not minimum) changes required to port the setup of dsPIC30 to dsPIC33 devices.

ToDo

  • dspic gcc compiler for constant problem
  • add chip to stable voltage upon power failure or to detect low voltage, and generate interrupt for dsPic to execute shutdown routine (e.g. save important data to NVM, shutdown ethernet etc.)
  • program the bootloader into flash under linux platform
