the Code they came up with is:
void setup() {
for (uint8_t pin = 14; pin < 14 + 32; pin++) {
pinMode(pin, INPUT_PULLUP);
}
Serial.begin(250000);
}
void loop() {
static unsigned long iterations;
static unsigned long lastSecond;
unsigned long topLoop = millis();
iterations++;
uint8_t pin = 14;
for (uint8_t bytes = 0; bytes < 4; bytes++) {
uint8_t eightBits = 0;
for (uint8_t bits = 0; bits < 8; bits++) {
bitWrite(eightBits, bits, !digitalRead(pin++)); // HIGH als 0, LOW
als 1
}
if (eightBits < 16) {
Serial.write('0');
}
Serial.print(eightBits, HEX);
}
Serial.println();
if (topLoop - lastSecond >= 1000) {
Serial.print(iterations);
Serial.println(F(" / second"));
iterations = 0;
lastSecond = topLoop;
}
}
the Arduino will spit out over 2000 times every second
