This is maddening. I’ve tried 2 virgin chips now with the same results. What am I missing? I get this error
avrdude: stk500_program_enable(): protocol error, expect=0x14, resp=0x50
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51
I’m using an Arduino UNO as the ISP. I’ve checked connections a dozen times all with the same result. I’ve attached the schematic. If anyone can help, please do. I’m pretty much at my wits end with this SMD crap.
