I am using nRF52 pca10400 and I would sample some audio signal for short periods of time, but I found a lot of difficulties with the SAADC example from sdk 13, since if I put a value greater than 126 in SAMPLES_IN_BUFFER I get overflow.
I would also increase the sampling frequency by the variable ticks, but the minimum value allowed is 1 [ms] for this variable since it is declared as uint_32. So it means I can reach a maximum sampling frequency of 1kHz (?).
Can I modify in some way the function nrf_drv_timer_ms_to_ticks in order to get a higher sampling frequency?
Thank you.
