This program is for ADC to DAC conversion. I am supplying an input voltage of 3V, expecting the same voltage as the output voltage. However, I am unable to view the output. I am supplying 3V using a power supply, and I want to view the output on the Oscilloscope. May i know what is the error in my program, i didn't encounter errors while building and debugging the project. And let me know which pin i should connect as input and out put
