/* Generation 7 Electronics Setup Test This small application turns on the power supply, blinks the LED of HEATER1 ten times, then turns off power again. If it works, your firmware has good chances to work as well. All activities are commented over the serial line, so if you listen there at 9600 baud and can read clear text, your serial line works as well. This example code is in the public domain. */ #define PSU_Pin 15 #define HEATER_Pin 3 #define BED_Pin 4 void setup() { int i; Serial.begin(9600); pinMode(PSU_Pin, OUTPUT); pinMode(HEATER_Pin, OUTPUT); pinMode(BED_Pin, OUTPUT); digitalWrite(PSU_Pin, HIGH); // initial value, off digitalWrite(HEATER_Pin, LOW); // intiial value, off digitalWrite(BED_Pin, LOW); // always off // test procedure delay(5000); Serial.print("turning PSU on\n"); digitalWrite(PSU_Pin, LOW); for (i = 0; i < 5; i++) { Serial.print("LED on\n"); digitalWrite(HEATER_Pin, HIGH); delay(600); Serial.print("LED off\n"); digitalWrite(HEATER_Pin, LOW); delay(600); } Serial.print("turning PSU off\n"); digitalWrite(PSU_Pin, HIGH); } void loop() { static int i = 0; delay(10); i++; if (i > 99) { i = 0; Serial.print("ATmega is idle\n"); } if (Serial.available() > 0) { i = 0; Serial.print("received <"); Serial.write(Serial.read()); Serial.print(">\n"); } }
