Part Number: INA219

Dear TI engineer:

Please find attached two snapshots of the waveform. These waveforms represent the execution of the same I2C code aimed at reading the INA219 power register.

However, the outcomes depicted reveal variations. The SCL is 388KHZ.

1. Read power register non-zero.

2. Read power register zero.

HI Shiang,

I'm not seeing an issue. When your power register is 0, the data is 0x00, and when you have a non-zero power register it shows a value. Is the value not what you were expecting?

Best,

Mohamed

Hi Shiang,

This seems to be a duplicate thread. I will close this thread and continue on the original.
