   Interface to the AD-converter of the ATmega32, which allows to query the potentiometer and the photosensor of the board. 
       Device ids of available periphery connected to ADC channels. 
  | Enumerator | 
|---|
| POTI | the potentiometer (rotation towards LEDs yields higher numbers)  | 
 | PHOTO | the photosensor (brighter ambience yields higher numbers) 
 | 
 
                                     | int16_t sb_adc_read | ( | ADCDEV | dev | ) |  | 
       
    Perform a 10-bit A/D conversion for a specific channel/device. 
 - Parameters
-         | dev | id of a device connected to the ADC |  
 
- Return values
-         | >=0 | 10-bit result of the conversion |  | -1 | invalid device id |
