问题
I am currently making a system using digital camera, my camera resolution is 384x288 4:2:2 YCbCr. My camera works on BT.656 with embedded sync (without hardware sync). I configured STM32 DCMI with embedded sync and it didn't work. Then I started to debug it and found some weird STM32 DCMI issue:
STM32 DCMI embedded for BT.656 is inverted.
STM32 DCMI document (out of ST's AN5020):
BT.656 Protocol (from here):
I have 2 questions:
- Has anyone been able to make BT.656 work on STM32H7 or any STF32FXX?
- BT.656 resolution for PAL is 720x576 but my camera is 384x288. What is the format of the camera? Or: How can I understand how many lines are used?
