Hello, I have some questions about the ad7780 driver. * What is the val2 In the line 96 (*val2 = chan->scan_type.realbits - 1;)? How it is used? Is it related to the 24-bits ADC precision? * Why there is a subtraction in the line 99 ( *val -= (1 << (chan->scan_type.realbits - 1)); )? Is the *val initialized with 0? Is that related to the formula described in the DATA OUTPUT CODING, at page 12? https://www.analog.com/media/en/technical-documentation/data-sheets/ad7780.pdf With regards On Thu, Oct 18, 2018 at 8:41 AM Giuliano Belinassi <giuliano.belinassi@xxxxxxxxx> wrote: > > On 10/18, Ardelean, Alexandru wrote: > > Thank you for the reply :-).
