Function Documentation

void adc_isr

(

void

)

ADC ISR routine.

This routine reads selected ADC value and multiplies it by ADC_MUL and adds ADC_OFFSET to calculate the volage (3.25mV/div). After this reading the next ADC channel is set up for measuring.

Here is the caller graph for this function:

void init_adc

(

unsigned

rx_isr_vect

)

Inicializes ADC service for all ADC (4) channels and installs ISR routine to VIC.

inicializes ADC lines and starts converion (use ISR)

Automaticly starts the conversion of first channel on given conversion frequency.

Here is the caller graph for this function:
