Dear Colleagues, I have purchased a PicStart+ as it supports all known PIC types. However, the programming software is integrated into the MPLAB IDE, and I don't like GUI, because of its instability and other disadvantages. I plan to write a simple programming software dealing with it, however, I need the communication protocol between PC and PICSTART+. I know the serial parameters are 19200,N,8,1, but I don't know the challenge-response sequences. I wrote to Microchip but I didn't got ANY answer. Could somebody help me? That software would be good also for Linux, I guess. Sincerely, Dr. Imre Bartfai University of Pecs, Hungary
