Interfacing with CCD TCD1103, timing problem

[RHooijsch]

Hello, I am trying to interface a CCD sensor (TCD1103) through the FPGA of LabVIEW and a NI9401 DIO module and a level converter. Currently, I look at the output on an oscilloscope but when I get a correct output I will try to read it out using the NI9201 Analog Input module.

I found the timing on the TCD1103 difficult to implement on the output sequence to communicate with the CCD. There are 3 lines that have timing requirements the SH, ICG, and Mclk. I coded the different lines in the FPGA but I have not yet found a way to synchronize the data lines. In my current codes, the pulses start to drift apart. 

I added an overview of my code and the timing chart.

Take a look at the "Digital I/O Applications" section of this white paper for an example that is pretty close to what you are trying to accomplish: https://www.ni.com/en-us/innovations/white-papers/06/advanced-data-acquisition-techniques-with-ni-r-....

Also, you should be using the Loop Timer function rather than Wait to control your, make sure you understand the difference.
