    Hello,

    Does the terminal have the same baudrate and stop bit? When you convert value to string, is the returned number of chars correct?

    Please add a breakpoint inside the sciSend(), and check if your data is written to SCI TD register? 

    HALCoGen has a very good example to display the ADC values on Terminal.
