Problem with USBH HOST STM32F429

[Ngama.1]

Hello there ,

Now iam developing an app on STM32F429ZI DISCOVERY BOARD ,, where I get mouse and keyboard input .

Every thing is working well until I use touchgfx GUI ,my app cannot set the right input device class ,

I wrote the same app using freertos without GUI and working well with another tasks , so I can manage priorities well .

And I noticed that VBUS activator pin (PC4) ,

is not stable , I tried it as analog input and it gives me completely wrong values and again it works well and give right values without touchgfx .

Any one know what is the solution for this problem ?

Thanks in advance .

Hi,

Were you able to find a solution to your issue ? The project seems quite interesting. Could you share that project so that I can try to replicate the issue ?

What revision of the STM32F429 discovery board do you have ? (look under the board for MB1075-F429I- <revision, for example E01> ) ? What version of TouchGFX are you using ? And which toolchain/IDE ?
