HI! I use 8-bit adc and i use the result conversion in ADCH which is produced in the wizard.I have given a DC voltage of 2.5V and I have got 128,but when I give a 40HZ sine and send the result to PC and plot with MATLAB the figure is very bad.I have also increased the sampling frequency but it was in vain. Please guide me! Thank you!
