Hi! Sorry if I'm a bit off topic with this! I'm wondering if someone as private person or as company has time and = want to help me out. I need to finish a program but because of sick leave I can't finish it. = Therefore I'm looking for someone who can finish the code I started or = redo it in their own way. It's started in CCS but could be done in MCC18 = or Hi-Tech also. What does it do! Wait for a packet on RS-485 from the computer handle = the packet and send pack a packet. There is three different commands in = the packet. Just ACK and tell it's there along with version number and = device ID. Write 2 config bytes to internal ee-prom and finally to send = a request on USART port to a DS2480B and send back the result. It's planned to use a 18F452 but a 16F877 can be used also. As they are = pin-compatible that's OK. If you have interest in this please send me a private mail. I can send = you the existing code and schematics and if needed a working = circuitboard. Testing program for windows also exists. Payment is agreed when we decide what do do or not. Hope there is someone with some time over!
