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 |
