If NSH_BUILTIN_APPS is defined, then the number of samples is provided
|
|
on the command line and this value is ignored. Otherwise, this number
|
|
of samples is collected and the program terminates. Default: 0 (samples
|
|
are collected indefinitely).

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

config EXAMPLES_ADC_SWTRIG

bool "Use software trigger"

default n
|
|
---help---
|
|
Some ADCs may be configured so there is no automatic or periodic
|
|
conversion of samples. Rather, the ADC sampling must be trigger by
|
|
software via an ioctl command. Select this option only if
|
|
applicable for your ADC configuration. In this case, the test will
|
|
issue the software trigger ioctl before attempting to read from the
|
|
ADC.
