Hello,Our custom HW uses a LSM6DSM sensor. There is no existing driving for it in Zephyr, however, the LSM6DSL sensor does. I looked at the differences between the 2 devices and it comes down to the LSM6DSM having 2 extra connection modes (Modes 3 &...

We have a custom antenna and reader board setup that uses the ST25R3916 reader chip and I would like to know how to implement the Discovery GUI "Tune Antenna" and "Measure Antenna" commands in my Test Application FW. Specifically, what functions need...

I'm new to ST25R2916B programming and the RFAL NFC library. I'm currently writing board bring-up firmware and would like to know the correct way of updating the AAT A/B values in both the CHIP_INIT and POLL_COMMON modes of the Analog Config table whi...

With regards to the amplitude and phase values, I see that these values are returned after the call to aatMeasure() in st25r3916_aat.c. The amplitude and phase values are returned as integers while the Discovery GUI returns the values as decimal numb...

Hi Ulysses,We have a custom antenna board for a reader board using ST25R3916. Since we can't hook up the custom antenna board to the Discovery GUI, my board bring-up FW will do the antenna tuning. We will save the AAT values resulting from that tunin...

Thanks, Ulysses.I did end up going into the Discovery GUI and exported the Analog Config table from there. In essence, I now have a "custom" analog config table (even though it contains the default values from GUI). I enabled the RFAL_ANALOG_CONFIG_C...
