TouchGFX GUI discovery/evaluation board recommendation

[DavePfz]

I recently acquired the STM32F469NI-Discovery board as it purported to support most of the functions that I wanted - GUI, USB OTG, SD card, etc. However, on bringing it up, it did not load and remained blank. (Customer support has not been supportive in getting the demo software loaded.) I have been able to run simple TouchGFXDesigner projects with ST332Cube. But, when I try to add simple functionality, I find that what's in he .ioc file does not agree with what's on the board (in the schematic). The best I have been able to do is determine that the promised sample code is not available.

Can someone recommend a newer board that has better support? The larger the display, the better. I can work with almost any daughter board configuration (Arduino, etc.) as long as it is well documented. A primary requirement is that the source code for the examples be easily accessed.

For those interested, this is to be used as a front-end controller for custom lab test equipment. The GUI is primarily to show data as it is collected. This is a process where the control and data vary continuously and the immediate feedback is important. Yes, could probably be done with a commercial product, but the budget is thinner than a shoestring!

Thanks, Dave

Hello @DavePfz ,

If you want to have a big display, I would recommend for the more recent and powerful STM32U5G9J-DK2 or STM32H7S7/8-DK boards that have a resolution of 480*800 but the chips can run bigger display.
They both embed NeoChrom which is a graphical accelerator.
The U5 is for low power while the H7 is for high performances, however, the H7 is still very affordable.

If you need more help on selecting the right MCU, you could get closer to your local FAE.

Both of those look like good candidates! I will pursue them further.

Thanks, Dave

Hello @DavePfz ,

I am glad to hear that!
Happy development. :)
