ADC input

[jacopoagostini]

Hi, I'm trying to configure the internal ADC for i.MX6ULL. How I can configure pin by software. I use the command echo 1 > /sys/class/gpio/export for digital I/O. Is there something similar?

Hi Jacopo

please look at available options described in sect.53.3.3 Programming Interface

attached Linux Manual. Pins can be configured using dts pinctrl_adc1: adc1grp entry:

Best regards
