Serial communication, PC & 3Pi

Support Robots
1

Hi,

I was wondering how can I communicate with a 3Pi over Serial communication (from computer) ? with AVR USB Programmer. AVR USB Programmer creates 2 ports on the computer which one is called programmer and other TTL Serial Port, but I didnt manage to send anything to 3Pi robot on any of these channels. Can anyone help me ? I am coding in Arduino C and trying to read the Serial communication with Serial.available() and Serial.read(). Am I doing something wrong ? Is there any other way ?

thx in advance

Hello, Shahab.

I’m sorry you are having trouble. Could you describe how everything is connected? In particular, how did you connect the programmer’s RX and TX lines to the 3pi?
