Tool/software:
Hello,
Im using an arduino to communicate with the MUX (over I2C). I can set the registers, read the values...
But I have very weird behaviour with the interrupt pin. It always triggers (reading INTCNTRL or Measering the actual pin) even tho the upper value and lower value are set like this:
//set MODECNTRL: ADC Mode Control Register (Address = 00h)
Wire.beginTransmission(Address);
Wire.write(B00000000); //reg
Wire.write(B11001100); //value
Wire.endTransmission();
//set INTCNTRL
Wire.beginTransmission(Address);
Wire.write(B00000001); //reg
Wire.write(B00000001); //value
Wire.endTransmission();
//set upper and lower limit of First ADC upper
Wire.beginTransmission(Address);
Wire.write(B00001010); //reg
Wire.write(B11111111); //upper limit value
Wire.endTransmission();
Wire.beginTransmission(Address);
Wire.write(B00001011); //reg
Wire.write(B00000000); //lower limit value
Wire.endTransmission();
//set INTCONFIG: These bits set the number of times the comparator threshold limit (either upper or lower) must be exceeded to generate an alarm.
Wire.beginTransmission(Address);
Wire.write(B00010010); //reg
Wire.write(B11100011); //value
Wire.endTransmission();
Do you have any idea what I'm doing wrong?
