Hello Thomas,
I follow the quickstart guide because the impedance analyzer I use doens't go beyond 1MHz. I can't determine the exact resonant frequency but use my calculated 2.64 MHz in step 4b. The sensor gives a prox data above 0 so I don't add a discrete inductor. When I arrive at point 4d and start changing Rp_min nothing happens. In the old version when I raised Rp_min the prox data would increase towards 2^15. In this version nothing happens as if the chip doesn't switch to the selected Rp_min.
I have a second EVM with the original coil and connected this one. When I change Rp_min: no change. I've noticed that when I reconnect the EVM while the Stop button is pressed the Rp_min and Rp_max values do change slightly even if I didn't change them before. Does the EVM do a self calibration when it powers up?
Regards,
Sietse
