Other Parts Discussed in Thread: DLPC2607
Hi, I have been using the DLPDLCR2000EVM for quite a while now and I am facing an issue that I have never seen before.
I was using the device coupled with a raspberry pi to display pattern by sending a PAN_DISPLAY command to my frame buffer, which would then send the command to the DLPDLCR2000EVM, then I would use the WAIT_FOR_VSYNC command to wait on the VSYNC signal from the DLPDLCR2000EVM.
since I needed every pattern to be displayed for the exact same amount of time, I previously used the mode lock-to-VSYNC, by setting a 1 in the register 0x1E of the DLPC2607 on the DLPDLCR2000EVM.
That used to work in the past but now I have reconfigured my Raspberry PI 3B and, for some reason, using this command creates a jitter in which the screen seems to be divided in two.
The lower half is displayed at the top and the upper half at the bottom.
To clarify my setup, my PI is connected to the EVM through a interface PCB.
I believe I must be using some parameters wrong either in the PI or the EVM as this display method has worked in the past but I can't seem to figure out what changed since this is happening.
Would you be able to provide a way to synchronise myself properly and avoid this jitter?
Thank you for your time,
Best regards,
