Hi to all,

Appreciate anyone can give a hand.

When DFR0972 and SEN0322 both program run in sketch.

DFR0972 output not update to ammeter by loop program wrtAOM().

My ammeter always show 4.73mA which is set by aomInit ().

See below information captured by serial monitor, look like this module is working fine,

but do not know why it did not update to output.

O2 Oxygen Transmitter
I2C to 0-25 mA analog current moudle initialization ... done!
[output(): 102 ] 775
[output(): 103 ] 774.77
[output(): 104 ] -2.26
[output_mA(): 84 ] 307
I2c connect success !
Button 3 state changed
oxygen concentration is 20.96 %vol
DAC value: 423
[output_mA(): 84 ] 1A7
Current value: 2.58
oxygen concentration is 21.06 %vol
DAC value: 2801
[output_mA(): 84 ] AF1
Current value: 17.10
oxygen concentration is 21.05 %vol
DAC value: 3289
[output_mA(): 84 ] CD9
Current value: 20.08

If I only run DFR0972 and block SEN0322 program, ammeter is updating and shown

current value from DFR0972 module.

Thanks in advance.
