Hello,
I am using multiple INA219 devices with I2C comms.
I am able to program the calibration register and read the value back. This works well on all devices.
However, I get intermittent ZERO value reads for Current, Power, and sometimes for VBus registers.
Power to INA219 is sources full time after power up.
After a single configuration transactions after start up, I periodically read current, shunt, bus and power registers.
The power register is the last register I read prior to the next read which is after 5 seconds. so no measured/calculated data is cleared.
I see lots of intermittent zero values.
Would you please help what causes the read not to be stable?
Thank you in advance for your help and support.
Best regards,
Ziggy
