Other Parts Discussed in Thread: HALCOGEN
Dear sir,
thank you so much for your reply sir.
Through UART i am sending the data and receiving the response as per the command structure given by client
only pending is adc
in adc i want to read the voltage and displaying in gui
i am using this AD7476SR
TZ-R2 in schematic 3rd pin as the input voltage of 3V
from bellow code iam receiving the response is 60159 constant. changing input voltage of ADC no change in output response

the above code is used to read the voltage of adc
i am taking the reference code from this video www.youtube.com/watch
i am trying to read the voltage of ADC .
iam attaching the snapshots for halcogen also sir.
please guide me
