So I have to make it ICSP to program for 877A? I got problem as programming with 877A. With 877 everything is oki, but with 877A, something goes wrong. This the first time I try with 877A.
Yes, you need programming software wich specifically includes the 16F877A... 16F877 and 16F877A are NOT the same, as far as programming is conserned...
bon bon, I found the problemes. I have 2 programmers one is RCD, and another is JDM. Well, I took the RCD programmer to connect to the 877 )
And it also cannot program for 877!!!! I didn't try with JDM yet, because i'm in the labo, not at my home. I cannot try it now, but I'll test this tonight.
Well, RCD is fully identical to JDM, but I put some effect with LEDs to see that the programmer is workings, and it uses 13V zener.
It's quite good for beginners with 16F84 or 16F628. Here is the link for beginners:
**broken link removed**
Use the jumper to connect pin RB4 (pin 10) to GND to program for 16F628. And use ICPROG at JDM programmer hardware option. To program for 628, reduce the delay time in hardware option to make it faster.
