RfLink & Ethernet (TCP232-T2)
Posted: 24 Apr 2019, 14:16
Hello,
i want to connect my mega2560 over ethernet with domoticz.
The Problem is, that the mega2560 doesn't receive my commands.
Sending(from mega to domoticz) works perfectly.
i have a chinese mega2560 board with a CH340G.
The Ethernet to TTL adapter is a USR-TCP232-T2 Module.
connection:
TX0 (Atmega) <--> RXD (TCP232)
RX0 (Atmega) <--> TXD (TCP232)
3.3V(Atmega) <--> 3.3V(TCP232)
GND(Atmega) <--> GND (TCP232)
I've already tested the atmega and the TCP232 with an serial to usb adapter(B75937). Both are working perfectly (sending and receiving).
but if i connect the tcp232 with the atmega i can only send from the atmega to the ethernet, but the atmega can't receive anything from ethernet.
I'm not sure if the Atmega uses Rs232 or RS485.
