The continuous conversion mode of the adc drive can only enable one channel at one time. For example: echo 1 > in_voltage0_en, then echo 1 > in_voltage1_en , prompt echo: write error: Invalid argument. When voltage0 is turned off, voltage1 can be enabled, as shown in the figure below.

Hello

The issue it is related to the ADC HW, this ADC Module has only one ADC so the Channels are muxed to input the ADC, this means if you are using the continuos mode only One Channel can be Muxed.


Have a great day,
TIC
