void adc_filter | ( | unsigned char | chan | ) |
Median filter for ADC.
If new data is available the median is recalculated. This function may be called from main function, it should take long time to calculate the median for all ADC value.
chan | bit oriented (0~3) value, defines which ADC channels have new data |
void init_adc_filter | ( | unsigned | rx_isr_vect | ) |
Inicializes ADC service for all ADC (4) channels and installs ISR routine to VIC.
Automaticly starts the conversion of first channel on given conversion frequency.
