Hello, I've started analysing both programmer I have. (One I bought - which works perfectly - and the other I've been trying to make it work!)
I used an oscilloscope in order to print the wave forms PIC received/trasmitted.
In the attached file, the first figure of each page is from AN589 and the 2nd is PICSTART PLUS (the programmer I bought).
I could notice there are many differences between them, mainly considering the data flow.
Also, I could realize the cable lenght (40 cm = 0.4 m) does not affect the process, cause both wave forms are the same (green probe = pc parallel output - pink probe = PIC data pin)
Kinda weird ic-prog, huh?... I wonder if there's another way to solve this problem...
What do you think about it?
