programmer is not responding

  • pms16 Saturday, August 22, 2015 6:01 PM Reply
    I have bought UNO R3 Board Module + Ethernet Shield W5100 Module Integrated Board for Arduino. But I have problems to load a simple sketch, e.g. Blink to it through Arduino IDE.
    I get following messages:

    Using Port : COM5
    Using Programmer : arduino
    Overriding Baud Rate : 115200
    avrdude: stk500_recv(): programmer is not responding
    avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0xdd
    avrdude: stk500_recv(): programmer is not responding

    Is there any documentation for this board (in english)?

    The Ethernet shield uses pins 0 and 1 (which are RX and TX, respectively), which are also pins used by the ethernet shield. Because of this, the programmer won't work if the shield is installed.

    You need to disconnect the Arduino, remove the shield, reconnect, upload your sketch, disconnect, install the shield and then power the Arduino.

    Keep in mind that while the ethernet shield is being used, you won't be able to use Serial to print messages to the console.
