Pickle is an PICMicro in-circuit serial programmer for FreeBSD, NetBSD, Linux, Cygwin (Windows) and MACOS/X or any UNIX/POSIX based system, which includes the Raspberry Pi and embedded devices running OpenWRT.

All operating systems support high voltage programming (HVP) of PICMicros with the Velleman K8048 or K8076 kits using a RS232 interface, yet many other high voltage programming kits may be supported with the appropriate configuration.

Support is also available to program low voltage programming (LVP) compatible PICMicros directly from a Raspberry Pi, OpenWRT enabled router or an USB UART adapter. Look for PICMicros marked LVP(PGM) or LVP(KEY) in the supported PICMicro device list.

Refer to the Microchip documentation for your PICMicro as to whether it supports high voltage (HVP) or low voltage (LVP) programming or both.

Currently supported PICMicros range from the PIC10 to the PIC32. Predominantly PICMicros available in DIP packages are tested and supported.

In order to use the program in Windows you must first install and setup Cygwin including the necessary development tools for building the application. See this page for details.

TOC

Pickle version 5.0 has been released. This version changes how ICSP interfaces are configured in the configuration file. The changes do not affect the RPi but do affect the legagy Velleman K8048.

Programming executive support has been added for PIC32MM 32-bit PICMicros.

Before you download and use the application you should read the LICENCE found here. This licence details the rights and liabilities of using the application and it should be especially understood that I, the author, will not accept any responsibility for any side effects of running it. Do not download and run this program unless you are willing to accept the consequences of it failing for any reason.

TOC

Pickle was originally written by Darron M Broad in 2005 as `k8048' to support the PIC16F627. `k8048' was updated in 2007 adding various other devices and more active development has occured since 2012 adding many more. The project was renamed from `k8048' to pickle in January 2015 as the Velleman K8048 kit became less relevant and superseded by the Raspberry Pi as the primary development platform.

Special thanks go to various people who helped over the years with this project!

Hardware with ICSP support.

TOC

The following tables list all the supported PICMicros. PICMicros in each table are grouped by family and at least one device of each family has been tested.

12-bit word / 8-bit data PIC10F/12F/16F architecture

14-bit word / 8-bit data PIC10F/12F/16F architecture

14-bit word / 8-bit data PIC16F architecture (new programming algorithm)

16-bit word / 8-bit data PIC18F architecture

16-bit word / 8-bit data PIC18F architecture (new programming algorithm)

24-bit word / 16-bit data PIC24/dsPIC architecture

32-bit word / 32-bit data PIC32 architecture

TOC

The PICMicros in the following table have been tested are known to work in specific modes of operation.

Code Y/N indicates whether an ICSP I/O test has been written for this device.

The three modes are as follows:

• HVP. High voltage programming at 9 or 13V.
• LVP(PGM). Low voltage programming with VPP and PGM at VDD.
• LVP(KEY). Low voltage programming with VPP at VDD and entry using a 32-bit key.

The legacy Velleman K8048/K8076 is incompatible with many modern devices and any advice is noted.

New algorithm noted in the comment column refers to the new PIC16F/18F programming algorithm incompatible with the older ICSP programming method.

Download the latest archive file pickle-5.0.tgz or check out the latest development version here tip.tar.gz.

Decompress and extract the application source code from the archive. Perform `sudo make && sudo make install', the application will be ready for use.

This has been tested on FreeBSD 5 and 6 yet should work on all FreeBSD variants and other BSD derived systems. It has also been test to work in Linux 2.6 but only compiled for 2.4.

A binary build is available for the RPi pickle-pi-5.0.tgz. This pre-built binary must be extracted as root into /opt/pickle.

Here are some sample sessions obtaining the source of the application and then compiling and installing it.

TOC

There are two ways to configure pickle; either use a dot file named `.pickle' in your home directory, else create a directory named `.pickle' and store the configuration in a file there named `config'.

The second option is to allow selectable configurations with the `PICKLE' environment variable, and also for storage of Programming Executive files for the 32-bit PICMicros.

The options are as follows.

On dsPIC/PIC24 and PIC32 devices, Microchip provide a `programming executive'.

This software is loaded into the chip to speed up ICSP.

Pickle supports ICSP with the programming executive (PE) on the PIC32 but not the dsPIC/PIC24 devices. Currently there are no plans to add PE support for the dsPIC/PIC24.

By default, PIC32 PE mode is not enabled and a few steps must be completed to activate this mode of operation.

If you have a .pickle file then rename it with a temporary name.

mv ~/.pickle ~/.pickle-config

Make a directory named .pickle in your home dir.

mkdir ~/.pickle

Move any old config into the new directory, renaming it to `config'.

mv ~/.pickle-config ~/.pickle/config

Download and unzip the programming executive from Microchip, Eg. for the PIC32MX150F128B.

cd ~/.pickle
wget -q http://ww1.microchip.com/downloads/en/DeviceDoc/RIPE_11_000301.zip
unzip RIPE_11_000301.zip

A file named RIPE_11_000301.hex will now exist in the .pickle directory. When we use p32, and it finds this file, it will automatically load it into the chip.

The following PE files are all that's required for the PIC32 range of PICMicros.

To test that the PE has been registered correctly, we can issue the id command, and if the PE is found the filename is shown. If the filename is not shown then something is wrong.

$ p32 id
[1D000000] [PROGRAM]  00008000 WORDS
[1F80F220] [DEVICEID] 14D06053 PIC32MX150F128B
[1FC00000] [BOOT]     00000300 WORDS
[1FC00BF0] [DEVCFG3]  CFFFFFFF
[1FC00BF4] [DEVCFG2]  FFF9FFD9
[1FC00BF8] [DEVCFG1]  FC67CF59
[1FC00BFC] [DEVCFG0]  7FFFFFFB
           [PE]       RIPE_11_000301.hex

The speed up when using the PIC32 PE to read and write to flash file is considerable. For example, programming 128KB without PE takes about 60 seconds on the RPi, with the PE it takes about 7.5 seconds. Verifying the same data takes 2 minutes without the PE and 5.5 seconds with it.

TOC

To demonstrate its usage we may utilise some assembly code supplied in the Pickles support package.

An example assembly file for the PIC16F627 on the Velleman K8048 kit sends the text “hello, world” over the ICSP lines to the host PC within an infinite loop.

The ptest command has a function to decode the text as sent above and dump it to the console, below is an example of assembling the assembly code file, writing it to the PIC16F627 chip and dumping out the text sent by the chip.

hg clone http://hg.kewl.org/pub/pickles
cd pickles/examples/pic16f627/
make

p14 program debug.hex
Total: 272

p14 verify debug.hex
Total: 272 Fail: 0

It is important to remember that on the Velleman K8048 the switch must be set to PROG. mode when writing to the chip and set to the RUN mode to execute code.
