RT1052 CSI & Bayer Input

[variable_andrew]

We have a camera connected to the CSI that provides data in Bayer 12-bit format.

We're able to get the image data and pretend it's just black/white data to either send over USB or display to an LCD, but what if we want to convert to RGB?

The RT1052 RM notes that the CSI accepts Bayer format data, but what can you do with this? As in: when CSI "accepts" the Bayer format data, and you can use CSI_CSICR2[BTS] to determine the Bayer tile start, is the CSI interface going to enable automatic conversion to RGB565 or RGB888 via the PXP perhaps? If so - how can you do this?

If the CSI and PXP are unable to do the Bayer to RGB conversion, then what is the purpose of setting the CSICR2 BTS bit? Just for statistics?

Hello Andrew,

The IPU can't support converting bayer format to RGB, it can only use generic mode to receive the CSI input bayer data to memory. To make the conversion you will need to use some graphics library.

Sorry for the inconvenience this may cause you.

Best regards,

Felipe
