Hello everyone,
I am working on ATmega8A for my graduation project. I have a problem about of multiple tx device and one rx device. If i need talk about my circuit; I am using ATmega8A as mcu this device is receiver and tx devices are one EM-18 RF ID reader module and PL2303 usb to ttl converter for computer communication between mcu. I am using toggle switch for change rx tx wires EM-18 between computer. But incoming datas is incorrect. For example, my rf id tag number is 360052A5266F but readed value is 6F 360052A526 360052A5266F. I don't use \ r when sending from computer, could it be because of this?
Thank you.
