|

*
|
||||
* Driver for the Zoul ADC sensors
|
||||
*
|
||||
* This driver supports analogue sensors connected to ADC1, ADC2 and AND3 inputs
|
||||
* This is controlled by the type argument of the value() function. Possible
|
||||
* choices are:
|
||||
* - ZOUL_SENSORS_ADC1
|
||||
* - ZOUL_SENSORS_ADC2
|
||||
* - ZOUL_SENSORS_ADC3
|
||||
*
|
||||
* To initialize the ADC sensors use the configure() function, using as first
|
||||
* argument SENSORS_HW_INIT, and choose which ADC channels to enable passing as
|
||||
* second argument any single or combined (sum) values as below:
|
||||
* - ZOUL_SENSORS_ADC1
|
||||
* - ZOUL_SENSORS_ADC2
|
||||
* - ZOUL_SENSORS_ADC3
|
||||
* - ZOUL_SENSORS_ADC_ALL (all channels above)
|
||||
*
|
||||
* Using an invalid combination will return ZOUL_SENSORS_ERROR.
|
||||
*
|
||||
* The decimation rate can be set by passing
|
||||
* ZOUL_SENSORS_CONFIGURE_TYPE_DECIMATION_RATE as the type argument to the
|
||||
* configure() function and then specifying the rate through the value
|
||||
* argument. Valid values are:
|
||||
* - SOC_ADC_ADCCON_DIV_64 (64 bit rate)
|
||||
* - SOC_ADC_ADCCON_DIV_128 (128 bit rate)
|
||||
* - SOC_ADC_ADCCON_DIV_256 (256 bit rate)
|
||||
* - SOC_ADC_ADCCON_DIV_512 (512 bit rate)
