Question

Can LTDC (LCD-TFT display controller) module be used for general digital video output?

Currently, i am developing a camera module using STM32F769NI.

When i was trying to figure out how to output the processed video data, i found LTDC module.​

I am wondering if this module can ​be used for digital output in general,

even if the LCD panel is not attached to the back.

Also, i am curious what this video signal level is (ex. LVCMOS).

Thank you.

> digital video output

This is a generic term saying nothing. There are numerous mutually incompatible digital video formats. LTDC outputs raw parallel RGB data.

what this video signal level is (ex. LVCMOS)

The same levels as every other STM32 GPIO. See datasheet.
