[AVR] Atmega16a ADC c code

[decapitary]

i have a analog signal i want to process the signal but i cant program my micro to do it...
any1 can help me with code? analog input USART output. plz note which pin is in and which is out!

You can try with two things basically as you have written Atmega16 So I am telling w.r.t that,

First Initialize ADC,
This Involves the bit setting responsible to start ADC and set Prescaler(Optional),

Then secondly make a Function to read ADC this happens
over a certain condition like (Wait for the Conversion mechanism to be completed), then read the value in the respective register,

then assign a Variable which receives the ADC converted data,
and finally Transmit that data via UART

So process is finally

main() {
// Initialize UART
// Initialize ADC

while(1)
{ 
// get data to a variable via Reading ADC
delay(); 
//Transmit the variable through Tx of UART
}
}

Post the circuit. We need to know what micro you are using and which adc channel.

its an EEG circuit like this https://people.ece.cornell.edu/land...rojects/s2012/cwm55/cwm55_mj294/img/whole.png

i used atmega16A intead of atmega644 i cant find c code for 1input and just one output for 6n137 and then USB drive

i write a code myself using this stuffs but didnt worked! i need full code

It is using one ADC channel and one digital output connected to an isolation circuit. What should the circuit (micro) do ? Read ADC value and do what ?
