Hez guys,
I want to build my own Arduino UNO, so I have started with this schematic and it works. My ATMEGA328p Chip is already bootloaded but I want to send some sketches with an USB TTL converter. I have this one:
I put RX to TX, TX to RX, 5V to 5v, GND to GND, DTR to the Reset of my Arduino. The CTS pin isn't connected.
My only problem is that I cannot send a sketch with the USB TTL Converter. I get some errors like this:
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x96
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x96
avrdude: stk500_recv(): programmer is not responding
