I need to hard reset (or seriously breathe life into) a stuck Arduino clone (Sunfounder UNO) which doesn't get recognized by Windows (error 43) after installing the wrong sketch. I am using the latest Arduino toolset and, before today, the setup was functional.
The problem is probably that I am writing to the serial in the setup()
section like this:
void setup() {
pinMode(a0, OUTPUT);
pinMode(a1, OUTPUT);
pinMode(a2, OUTPUT);
pinMode(b1, OUTPUT);
pinMode(m0, OUTPUT);
pinMode(m1, OUTPUT);
pinMode(m2, OUTPUT);
pinMode(OK, OUTPUT);
pinMode(KO, OUTPUT);
pinMode(carry, INPUT);
pinMode(result, INPUT);
delay(1000);
Serial.begin(9600);
Serial.write("Arduino Tester v. 0.1\n");
}
Arduino seems to be running the code. The problem is that Windows doesn't recognize it and doesn't set up a COM port for it.
So: i'd like to nuke it and restart from scratch.
How is this done?
