  • I am trying to udgrade my firmware to V13. I got the code and created a new sketch named GeigerCounter where I’ve added the Main.c. The source compiles ok but I cannot complete my Upload.

    I invariably get the following error: avrdude: stk500_getsync(): not in sync: resp=0x00

    The latest FTDI drivers are installed, i’ve tried selecting all teh boards with ATMega328 but get teh same error.

    I see teh green LED blink during the upload but it looks like the controller does not ack back anything.

    Any ideas what can be wrong? Thank you in advance

No public wish lists :(
