reset()

reset([deviceNumber]);

‼️ This library is now deprecated and has been replaced by the INA library. All existing INA226 functionality and functions have been implemented ‼️

This function writes a reset flag to the configuration register of the INA226 specified in the optional "deviceNumber" parameter, defaulting to resetting ALL devices that were located. This is a software reset, equivalent to turning it off and on again. The reset is fast, at 40 microseconds.

The INA226 will have the following default settings upon restart:

• Don't average readings
• Use a conversion speed of 1.1ms per Bus conversion
• Use a conversion speed of 1.1ms per Shunt conversion
• Continuously convert both Bus and Shunt measurements
• Clear the calibration register

The values for amps and watts will be returned as 0 since the calibration register has been cleared. The begin() function needs to be called again with the appropriate parameters to once again fill the calibration values.

Example:

INA226_Class INA226(); // Instantiate the class
void setup() {
  INA226.begin(50,100000); // 5V bus with maximum current of 500mA
                           // A 0.1 Ohm shunt resistor generates 50mV max
  int32_t busMicroAmps= INA226.getBusMicroAmps();
  Serial.print("Bus amperage is ");
  Serial.print((float)busMicroAmps/1000,3);
  Serial.print(" mA\n");
  INA226.reset()
  int32_t busMicroAmps= INA226.getBusMicroAmps(); // value will now be 0
  Serial.print("Bus amperage is ");
  Serial.print((float)busMicroAmps/1000,3);
  Serial.print(" mA\n");

} // of setup
void loop() {
} // of main loop
