Function Documentation
◆ InitADC()
| void InitADC | ( | void | ) |
Initializes the On Chip ADC.
The ADC is set to free running mode at 115.2kHz clock. This gives one result every 113us or one complete set every 564us.
◆ ISR()
| ISR | ( | ADC_vect | ) |
ADC Conversion Complete Interrupt.
Calculates the Value of the current channel and switches MUX and REF to the next channel.
The flag ADCFLAG_NEWRESULTS (all channels have been updated) will be set every 564us, ADCFLAG_NEWAVERAGES will be available every 36.1ms.
Optimization for Size (-Os): This routine takes about 37us worst case.
