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.
