adc Read from ADC

A mindlessly simple test of an ADC devices. It simply reads from the ADC device and dumps the data to the console forever.

This test depends on these specific ADC/NSH configurations settings (your specific ADC settings might require additional settings).

• CONFIG_ADC – Enabled ADC support.

• CONFIG_NSH_BUILTIN_APPS – Build the ADC test as an NSH built-in function. Default: Built as a standalone program.

Specific configuration options for this example include:

• CONFIG_EXAMPLES_ADC_DEVPATH – The default path to the ADC device. Default: /dev/adc0.

• CONFIG_EXAMPLES_ADC_NSAMPLES – This number of samples is collected and the program terminates. Default: Samples are collected indefinitely.

• CONFIG_EXAMPLES_ADC_GROUPSIZE – The number of samples to read at once. Default: 4.
