hi,
thanks for the burnLVP project. Being in a scripting language makes it easy to modify.

i was able to use it to burn PIC4550 using Rpi.
i then started to see if i could use it to burn the PIC using a USB-Serial converter.
i had some success. Programming code memory works, but reading EEPROM does not.
my effort is documented here : http://chaukasalshi.blogspot.in/2014/12/pic-programmer-using-usb-to-serial.html
i would like to contribute it to the main project, if you feel its useful.
it involves a bit of refactoring so that the interface is encapsulated within burnGPIO, and exposed via methods like set/getData/Clock/PGM/MCLRState().
The changed code is available at http://milunsagle.org/webroot/downloads/

Hello friend.

First of all, i wanna give you concratz for your job doing things like this python programs.

I have some error when i try burn PIC12LF1571 from my RP3-B+ GPIOs with external power-suplly (3V3).

I normaly burn it in windows with ICD3 (MPLAB-X) but i need do some tests with RASP and i need to burn it in same system, but i cant connect my programmer (ICD3) in my Rasp because they dont have drivers for it. So i see your "burnLVP" program and i think its a solution.

I try with "burnLVPx.py" and "burnLVP.py"
The error:

pi@raspberrypi:~/burnLVP/burnLVP $ sudo python burnLVPx.py ~/Desktop/FW-PIC/production.hex
Raspberry Pi GPIO
File " /home/pi/Desktop/FW-PIC/production.hex " loaded

Can you help me?

Many thanks.

hi dan,

i wanted to upload the attached image file to usb2ser branch, but could not do it thru the browser interface. Could you please do it for me when you find time ?

When burning EEPROM for 4550, the ReadDataPic18() function seems to be missing. its defined in burn18.py, which is probbaly deprecated. i guess it should also be defined in CpuPIC18F.py or the 2XXX one ?
