config EXAMPLES_ADC
	bool "ADC example"
	default n
	depends on ADC && LIB_BOARDCTL
	select BOARDCTL_ADCTEST
	---help---
		Enable the ADC example

if EXAMPLES_ADC

config EXAMPLES_ADC_DEVPATH
	string "ADC device path"
	default "/dev/adc0"
	---help---
		The default path to the ADC device. Default: /dev/adc0

config EXAMPLES_ADC_NSAMPLES
	int "Number of Sample Groups"
	default 0
	depends on !NSH_BUILTIN_APPS
	---help---
		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).

config EXAMPLES_ADC_GROUPSIZE
	int "Number of Samples per Group"
	default 4
	---help---
		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.
