RF iki yönlü seri haberleşme PIC 16F877A CCSC PICC - Full duplex serial communication

iki yönlü seri haberleşme ccs-c picc
Full duplex serial communication

projede iki adet pic16f877a kullanılmış
1. mikrodenetleyiciye bağlı 8 adet buton ile karşıdaki
mikrodenetleyicinin d portuna bağlı ledlerde gösteriliyor.
ayni şekilde ikinci mikrodenetleyiciye bağlı butonların değerleri
1. mikrodenetleyicinin b portuna bağlı ledlerde gösteriliyor
* veriler paket halinde gönderildiği için data aynı anda gönderilip alınıyor.
