USB to Serial Help


i want to use the USB to serial from Pololu, now i’m using ATmega16, i can send data from uC to my PC, but i can’t send data from PC to my uC, maybe i need a test program from Pololu, thx

We don’t have any ATmega16 examples here. But if you post your code, maybe there will be an obvious problem that we can see. Have you tried using the Pololu Serial Transmitter on the PC side, to make sure that it is not a problem with your PC code? Another thing that helps is to connect an LED to the TX line so that you can at least see that the PC is transmitting something!
