AVRADCSetupFunction to initialise ADC of AVRCalling Sequence
AVRADCSetup(uint8 prescaler, uint8 adc_ref)
Parametersprescaler: prescaler to be used for generating ADC clock (0-7)adc_ref : reference voltage to be used for ADC conversionDescription
This function initialises ADc of AVR with given parameters. 'prescaler' is needed for deciding ADC clock. ADC clock should be between 50KHz and 200KHz and it given as (MCU clock/2^prescaler). Select appropriate prescaler depending on MCU clock. 'adc_ref' selects one of the available reference voltage sources available.
The adc_ref can take the following values-
0 -> Voltage on VREF pin1 -> Voltage on AVCC pin2 -> Internal 2.56 reference voltage
This is curretly dummy function. It provides no functionality but is required for providing support for generating C code for AVR.
