| 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. |
