    Would like to ask how to troubleshoot my circuit which i input 5V to my Encoder and my encoder Dout were connect to Transmitter.
    At first the circuit were work and my receiver can receive the data even the oscilloscope show the clock pulse and data.

    When the next day i retry, the Transmitter circuit are not able to work. I check it with oscilloscope there are not clock pulse and data are zero.

    What should i do to confirm whether my encoder or transmitter spoilt???
