Which port of ATmega32 is used for ADC?
Let us see how to use the ADC of AVR ATmega16 / ATmega32. ATmega16/32 supports eight ADC channels, which means we can connect eight analog inputs at a time. ADC channel 0 to channel 7 are present on PORTA.
How many analog channels are available in ADC of ATmega32?
This means that you can connect up to eight analog input signals to the Atmega32 ADC, but at each conversion, only one channel input is converted. So, at each conversion, you should first choose the input channel to convert before starting the conversion. This is also done in the ADMUX register.
What is ADC AVR?
The ADC of the AVR converts analog signal into digital signal at some regular interval. This interval is determined by the clock frequency. In general, the ADC operates within a frequency range of 50kHz to 200kHz.

What is the ADC in AVR ATmega16 / ATMega32?
AVR ATmega16/ATmega32 has an inbuilt 10-bit ADC (Analog to Digital Converter) to convert Analog voltage to a digital value. Your browser does not support JavaScript!
Which is the reference voltage for ATMega32 MCU?
In Atmega32 you can use one of three sources for the reference voltage: An internal voltage from within the Atmega32 MCU. This voltage is set to 2.56V and cannot be changed. The AVCC pin can be your reference voltage, but this pin must be connected to the VCC and in this case, your reference voltage is the VCC
Which is the 10-bit function in ATmega?
It is 10-bit ADC. Converted output binary data is held in two special function 8-bit register ADCL (result Low) and ADCH (result High). ADC gives 10-bit output, so (ADCH : ADCL) only 10-bits are useful out of 16-bits. We have options to use this 10-bits as upper bits or lower bits.
What is the resolution of an ADC on a MCU?
For this a ADC or analog to digital converter is needed. Most modern MCU including AVRs has an ADC on chip. An ADC converts an input voltage into a number. An ADC has a resolution. A 10 Bit ADC has a range of 0-1023. (2^10=1024) The ADC also has a Reference voltage (ARef).
