ADC_Init
Void ADC_Init (Typ_ADC_InitParameter InitValue)
Initialization of the ADC, sets by default, channel to AIN0,
speed to default value of the device, ADC off, amplifier off,
interrupt disable and Continous conversion mode. You
can pass one or more input parameters by logically ORing
them together to change the default configuration.
ADC_SPEED
Fadc=Fcpu/4 or Fcpu/2 or Fcpu, depending upon the de-
vice selected.
ADC_SLOW
It is used together with ADC_SPEED to configure ADC
clock for device.
ADC_ONESHOT
One shot conversion active
ADC_AMPLIFIER_ON
Amplifier on
ADC_DEFAULT
sets ADC in default configuration.
ADC_IT_ENABLE
Interrupt enable for end of conversion.
None
1. Configure IO properly.
