    Photodiode current sampling using USB

      Hi all,

         

      I'm trying to build a system to characterize lasers, I'm collecting the light output using photodiode and connecting it to ADC, the output from the ADC is sent to a software called makerplot using USB connection. I just would like to make sure I'm doing it in the right way in terms of routing and sending the serial data on the right way. It seems that my code is not doing exactly the required as there's no data received in the software. I have my clock setting as required. Am I using the USB connection in the wrong way? I'm initiating the ADC to produce a byte value which should be sent through the USB,

         

      You find my project attached

         

      Thanks in advance.
