Camera buffer to LCD buffer doesn’t work correctly

[idrissmc]

Hello @Community member​ ,

i implemented the DMA, the DCMI, LTDC and DMA2D with their interruptions but I got something incorrect.

how can I solve this?

Break the problem down into stages, and follow the data.

Off board the data from the Camera/DCMI, confirm it is valid.

Signal interrupts via GPIO, scope signals, make sure they occur at expected periodicity.
