Just bought the EASY328 w/ATMEGA328 and I'm trying to Upload simple blink sketch with no success. I am using the ET-USB/RS232 mini adaptor for the connection to the board. I have installed the driver for this several times and I'm failry confident the USB adaptor it is working OK. It shows up in Windows device manager correctly, and it also show up as COM4 under Tools>>Serial Port within the Ardunio software. However It does NOT power up the board as I though it should. I have to power the board using a 12V dc supply. When I try to Upload I get:
avrdude: stk500_getsync(): not in sync: resp=0x00 avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x00
I have tried selecting several different boards since I'm not sure which one I have, ( all with the "328" in them and even some others). I am using a baud rate of 19200. I chose this becuase it is the only speed I can get any legible response from the board using the serial monitor. The board does seem to be responding or brodcasting back through the serial monitor if the if the USB/RS32 is connected and the board is Powered by external 12V supply. I see this same issue in some other posts but I havn't found one that has a solution? Any help would be appreciated.
