uint8_t | channel, | ||
uint16_t * | raw_adc | ||
) |
ADC 21 read raw adc function.
This function reads raw ADC value from the selected channel by using SPI serial interface.
[in] | ctx | : Click context object. See adc21_t object definition for detailed explanation. |
[in] | channel | : Input channel selection (0-7). |
[out] | raw_adc | : 12-bit raw ADC value. |

uint8_t | channel, | ||
float | avcc, | ||
float * | voltage | ||
) |
ADC 21 read voltage function.
This function reads raw ADC value from the selected channel and converts it to proportional voltage level depending on the avcc selection.
[in] | ctx | : Click context object. See adc21_t object definition for detailed explanation. |
[in] | channel | : Input channel selection (0-7). |
[in] | avcc | : Voltage on AVCC (3.3V by default). |
[out] | voltage | : Output voltage level [V]. |
