All of the examples appear to use the PDM FIR driver from the pdm_fir
directory. This is from five years ago, so i do not remember it very well, so i cannot see any PIR implementation based on a lookup table. The PDM FIR library is also referenced in the credits section of the readme.
Thank you for the clarification, by LUT i meant the byte_coeff LUT in pdm_fir.h. Anyway this example is an interesting use case of LoRa (off gird communication, bike/motorbike communicators). I thought of that with SX1280 at the time but never with SX1262, although i doubt it can comply with EU and possibly US regulations due to the 1% duty cycle requirement (unless using a constant channel hopping scheme maybe). I will try to test it with STM32F401CC and ICS-41350.
Hello, are you using the PDM library of ST or are you only using your simplified PIR based on the LUT? i see both in the project.
