It's possible to use TouchGTX with nucleo-F746ZG and a custom TFT display through SPI interface?

Hi,

Yes it should be possible to use TouchGFX with this board. I have never done it personally and we do not have Application Templates for this board available on TouchGFX Designer. You could start from a CubeMX project with the appropriate board but you will have to do the settings of your display and touchGFX yourself accordingly to your setup. Here is a link to the board bring up documentation that will help you in this process.

Hello,

Yes it should be possible. You have to make sure, you have enough internal RAM or an external RAM if the internal RAM is not big enough to fit at least one framebuffer for your screen. If you only have the internal RAM and the Framebuffer does not fit, you can use the partial framebuffer feature. Unfortunately, we don't have examples yet for a partial framebuffer with SPI interface. This will be done for September.

An external flash for the assets is also recommended.

The bottom line is that it is possible but you will have to code some parts yourself (mainly the SPI communication and some functions regarding partial framebuffer).
