This is the API for the PICkit 2. It is quite the same as PICkit 1
except the bootloader function.
To get it work under Linux, there are several step.
1) Port usb_pickit (for PICKit 1 only) to PICkit 2.
2) fix the remaining problem of usb_pickit (save OSCCAL value, etc)
3) Port the bootloader to Linux
4) extend the chip support. The 1st thing to do is to implement
"8" (Write 8 words to program memory) to support new PIC16 and PIC18 device.
dsPIC support may not be so easy. :(
Now I am trying step 1. I will report back the progress.
Regards,
Xiaofan
