Interfacing Piccard with PIC16f628a?

[Melanie]

This takes me back. I remember doing this at University ten years ago... (everybody at the Halls of Residence was watching free Satellite Pay-TV)!

1. You create an EEPROM LOADER program for the PIC.

2. You then run that program to transfer your Data into the EEPROM.

3. You then load the PIC with your applications program.

The card is then programmed and ready to run. This was a three-stage process (if you got the card with a 16F8xx PIC, you could actually do it in one hit because it had the Program Codespace to embed your EEPROM Data into it, but that just wasn't possible with the F84 card).

Thank you Melanie for helps, i know how to program it useing infinity or phonex programer that stoped 6years ago they were watchin tps and d+ and tv cabo sat channels over here but its gone early, well i just thought i can write a code for this bloody card so i can read and write its external eeprom useing pic16f628a,

Just use something like Pheonix to put a simple Comms program into the F84 for PortB.7 (not PortB.0 as in your code at Post #2 above) to talk to your F628, then it's just dialogue between the two to determine what you want to do... ie put Data into the EEPROM, or read back/compare etc.

Start by simply sending ONE character from your F628, receiving it on the F84 card, and sending it back a few milliseconds later. Once you have managed reliable communications between the two, you can then build on that and add features.

ok ty Melanie i will try this and see wat will happen,
