  • Initializing hardware for gen4-FT813-70CTP-CLB

    Where can I find the display timing parameters for the lcd panel (i.e. data sheet)? I need these parameters to configure the display initialization registers in the FTDI FT813.

    Hello:

    From the example that's referenced in the Getting Started Manual, I found these settings in gpu.h. I have the gen4-FT813 display running off the EVE Screen Editor v3.3 through an VA800A-SPI module. I created a custom device using these settings in the EVE Screen Editor. Able to connect to the display and boot up ok, but can't get anything to display. Any suggestions from this community would be appreciated. @4D please the post data sheet for the lcd used on gen4-FT813-70CTP, ty.

      Hi helloworld,

      Sorry about this information being missing from the Datasheet. This will be rectified next week and the FT81x datasheet will be updated with the relevant timing information.

      For the time being, here is the display datasheet for the 70CTP display used in that module, hopefully this has what you are looking for. Please let me know if it does not.
