Hallo,
Ik heb een vreemd probleem.
Ik het een programma gemaakt om 4 power sensoren (INA219) uit te lezen. Dit werkt goed op een Uno. Alleen omdat het straks op een Due moet draaien had ik hetzelfde programma op een Due gezet en dan werkt deze maar een paar seconden.
Ik kom er niet uit en heb geen idee waar ik dit moet zoeken.
Moet je voor I2C nog iets extra's doen op een Due?
Hieronder staat me code:
#include <Wire.h>
#include <Adafruit_INA219.h>
Adafruit_INA219 SensorU24; //0x40
Adafruit_INA219 SensorU12(0x41);
Adafruit_INA219 SensorU5(0x44);
Adafruit_INA219 SensorU3(0x45);
void setup(void)
{
Serial.begin(115200);
while (!Serial) {
// will pause Zero, Leonardo, etc until serial console opens
delay(1);
}
uint32_t currentFrequency;
Serial.println("Hello!");
// Initialize the INA219.
// By default the initialization will use the largest range (32V, 2A). However
// you can call a setCalibration function to change this range (see comments).
if (! SensorU24.begin()) {
Serial.println("Failed to find SensorU24");
}
if (! SensorU12.begin()) {
Serial.println("Failed to find SensorU12");
}
if (! SensorU5.begin()) {
Serial.println("Failed to find SensorU5");
}
if (! SensorU3.begin()) {
Serial.println("Failed to find SensorU3");
}
// To use a slightly lower 32V, 1A range (higher precision on amps):
//ina219.setCalibration_32V_1A();
// Or to use a lower 16V, 400mA range (higher precision on volts and amps):
//ina219.setCalibration_16V_400mA();
Serial.println("Measuring voltage and current with INA219 ...");
}
