I am coding and trouble shooting a board with a AFE4300 on it. I've found I have a lot of offset from the time I read the Zero value of the load cells to the time I read the "loaded" value. from the time the power is applied and 1st reading is made, it's taking over 6 seconds for the channel to stabilize.
This is with the channel shorted to it's IMH counter part (and 0.866V) bias applied (gain Rs = 5K = x41 on 1st stage). with the inputs shorted, I should not see any affects of my external RC filters but I see the single channel drift from more negative toward zero regardless of the gain setting or DAC offset value.
Is this internal drift if the WT input section to be expected? if not, where should I look to speed up the process?
Thanks,
Marty
can't seem to include plot so here is (6 seconds) of the 64sps ADC data.
