I’ve a camera design that incorporates an MCU and AR0134CS image sensor. Due to availability, I want to consider changing to MT9M034. It looks pin compatible and the main difference is it uses a rolling rather than global shutter. The MCU is currently running custom firmware to interface with the AR0134CS. Has anyone worked with both image sensors and so able to let me know how involved the firmware changes will be. I imagine (dangerous) that the changes could be minor and relating solely to register settings and addresses (e.g. binning may be done differently etc). If it’s relevant, the image sensor is being used in single capture mode.
