Hello everybody I am trying to make an STM USB HOST and taking some datas from keyboard and this data will show on LCD Panel. But somehow I can't set the pins by using CubeMX. The program gives error when I try to open TFT-LCD properties after I opened USB HOST Mode. The program says the two features use the same pins. Is it possible to open same properies at the same time?
Part numbers beginning with STM32F429I are in 176-pin packages that have enough pins to support both TFT and USB-FS at the same time. I've tried it in an empty project with a STM32F429IET MCU, the USB pins ended up on PA11 and PA12, and the TFT pins are all over the place (layout designers just love it). Now trying to find out what can cause the conflict. Clicking on PA11 reveals that the pin could be configured to LTDC_R4, but this function is assigned to PH10. Click on PA12, it could be configured to LTDC_R5, but this function is mapped to PH11. Of course, if you have set PH10 or PH11 before to some other function, then you have a problem.
Now I have a feeling that you are not designing hardware but trying to do stuff on an existing board. In this case, you can't define the pinout. Find the board schematics in the documentation, then work from there, assigning functions to pins according to their intended function. Trace the connections from the USB socket to the MCU to find out which pins are connected to it, then use the pin function mapping table in the datasheet to find out which USB controller can talk to it. Then activate that interface in CubeMX, and verify that it got mapped to the right pins. If not, you can hold down CTRL and drag it to the right place. Pin down the verified pins with the right mouse key, otherwise CubeMX will rearrange them at the hint of a conflict. When all pins are set, save a backup of the project as a baseline to return to when you start another software project on the same board.
