I send message
Please check inbox

I understood.Intelligent project.Thanks for explanation.Can I upload your circuit to my personel electronic web page www.izoelektronik.com ?
...Not:İzin verirseniz devreyi siteme koyabilir...

Can you explain that how its work?

You can send me Turkish explanation to my inbox. :)

İf you want to communicate many chip.You will use RS485 protocol.But when device send data dont able to recive data at same time.

If your PIC have UART.I think right way is using HSERIN. :)

You can watch video, see photos and download pbp asm isis files.

Thanks :)

Edit:You can download files
