Yikes! Try holding down the reset button and uploading the blink sketch.
I tryied and didnt work
If reset button is hold, I have this message:
And if I release the button, I have this message:
Binary sketch size: 1018 bytes (of a 32256 byte maximum)
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x00
If this doesn't work, do you have another arduino? Cause then you can program it over ICSP...
I can try, but don't know how, because the Tx is constantly trying to send signal to lcd.
I have another arduino.
When I pressed the 'upload' button to copy the message, it worked
And I tryied that more than 50 times, with all possible combinations:
Holding the reset button, then plugging the USB and send program, plugging and then pressing reset and send, etc...
Maybe the key is send the program in the exact moment that the arduino bootloader is charged, and the program isnt still running.
The solution was:
Plug the USB, and after... ¿600 ms? (Dont know) press the 'send' button. Not reset button needed
