Question
STM32H7 TouchGFX cannot find HAL library files
I enabled a UART peripheral in my touchgfx project. When I ran the project in STM32CubeIDE, it gave an error saying the HAL_UART_Init function was undefined. When I checked
${ProjectDir}\Drivers\STM32H7xx_HAL_Driver\Src
There were no HAL library files, so I pasted them in the folder:
This allowed STM32CubeIDE to compile and run the program. However, when I try to "Run Target" in TouchGFX, it gives the following error:

FailedIt seems TouchGFX is looking for the library files in a different folder than STM32CubeIDE, because it isn't compiling stm32h7xx_hal_uart.c
Am I overlooking something? Thanks for the help.
