|
|
*
|
|
* The ADC wrapper implement analogue sensors on top of the ADC interface,
|
|
* obscuring the ADC configuration and required calculations to obtain actual
|
|
* sensor values. The driver allows to reuse the adc-wrapper implementation and
|
|
* add sensors easily, without duplicating code, providing also a simplified
|
|
* interface and exposing the available ADC assigned channels by a given
|
|
* platform.
|
|
*
|
|
* To use a given sensor simply use: adc_sensors.configure(SENSOR_NAME, pin_no),
|
|
* where pin_no is a given pin in the PA port, check out the board.h for more
|
|
* information on available pins. To read a value just use
|
|
* adc_sensors.value(SENSOR_NAME), the expected result would be the sensor value
|
|
* already converted to the sensor variable type, check the adc-wrapper file
|
|
* for more information.
