bought arduino due, running 10 times slower. delay(1000); 10 seconds waiting. Would you please help?
Really strange !!
When you upload this snippet, what is the result you get in Serial monitor:
void setup() {
Serial.begin(250000);
Serial.print("Systemcoreclock = "); Serial.print(SystemCoreClock/1000000);Serial.println(" MHz");
// output:
//Systemcoreclock = 84 MHz
}
void loop() {
}
