Hello, I recently bought a Arduino UNO R4 WiFi and it does not work properly with even a simple sketch like this:
int incomingByte = 0; // for incoming serial data
void setup() {
Serial.begin(9600); // opens serial port, sets data rate to 9600 bps
delay(5000);
Serial.println("<READY>");
}
void loop() {
// send data only when you receive data:
if (Serial.available() > 0) {
// read the incoming byte:
incomingByte = Serial.read();
// say what you got:
Serial.print("I received: ");
Serial.println(incomingByte, HEX);
}
}
I am wondering if there is a way to factory reset and/or flash new firmware onto the UNO R4 WiFi without the IDE.
-Thanks
