Configures the NuttShell (nsh) over USB Serial (check usbserial configuration) and enables ADC 1 on channels 0 and 4.
|
||||||
|
NSH commands::
|
||||||
|
|
||||||
|
nsh> adc -h
|
||||||
|
Usage: adc [OPTIONS]
|
||||||
|
|
||||||
|
Arguments are "sticky". For example, once the ADC device is
|
||||||
|
specified, that device will be re-used until it is changed.
|
||||||
|
|
||||||
|
"sticky" OPTIONS include:
|
||||||
|
[-p devpath] selects the ADC device. Default: /dev/adc0 Current: /dev/adc0
|
||||||
|
[-n count] selects the samples to collect. Default: 1 Current: 0
|
||||||
|
[-h] shows this message and exits
|
||||||
|
nsh> adc -n 2
|
||||||
|
adc_main: g_adcstate.count: 2
|
||||||
|
adc_main: Hardware initialized. Opening the ADC device: /dev/adc0
|
||||||
|
Sample:
|
||||||
|
1: channel: 0 value: 2684
|
||||||
|
Sample:
|
||||||
|
1: channel: 4 value: 2682
|
||||||
|
|
||||||
|
Currently there is a bug that causes the application to always read the same value for channel 0 and 4. If you want to read the value from channel 2, you will need to enable the config "ADC1 Scan Mode".
