i bought a TSC1641 evaluation board, I can't read the power information from the DC power register. I can successfully read shunt voltage, current, load voltage data.
the configuration is as follows:
Rshunt register value = 0x01F4; the shunt resistance on my semim development
board is 5 mili ohms.(decimal=500).
configration register value = 0x0037; conversion time 1024 µs (default),
7h: shunt and load voltage, continuous mode (default).
I check the FLAG register data zeroth (CVNF) bit to see if the data is ready,
but regardless of this, I do a reading at any time.does this cause problems
with reading dc power information?

the problem is solved. I noticed that I was getting an error because the power value I was trying to measure was less than 25 mw (DCpower_LSB is set to 25 mW.)
I took successful power measurements when I increased the amount of load I connected to the circuit, allowing more power to be drawn.

Good - please mark the solution!
