I'm working on a project using an STM32H753 micro. The device has an LCD with touch screen. The touch screen logic has an interrupt output which triggers the micro to read the current coordinates when the display is touched. I'm using a GPIO pin c...

I'm working on a project using an STM32H753XI MCU with a touch display. I am not currently using TouchGFX. I would like to preload images into the onboard QSPI during the project load. How do I go about doing this? I have used TouchGFX designer o...

Regarding this memory declaration section in the .id file, what does the "x" in the parenthesis represent?/* Specify the memory areas */MEMORY{ FLASH (rx) : ORIGIN = 0x08000000, LENGTH = 2048K DTCMRAM (xrw) : ORIGIN = 0x20000000, LENGTH = 128K RAM_...

I'm working on a project using an STM32H753XI. The board is using a GT911 touch controller for the LCD. To configure the I2C address I have to control the interrupt pin during reset either high or low. This means I need to configure the MCU pin co...

I created a project for an STM32H753 MCU and have added FreeRTOS via CubeMX called from CubeIDE. CubeMX generates the following code in main.c: /* Init scheduler */ osKernelInitialize(); /* Call init function for freertos objects (in freertos.c) */ ...

Thanks Carl! That was it. The pins for the first change I made fell within the range shown in your image. Evidently CubeMX carried that over. The next change I made fell outside that range and that is when CubeMX cleared this setting.

Good idea. I'll try it. If nothing else it may help determine the issue.

Thanks for the responses. I need to clarify. I've gotten the touch interface to work just fine with the GPIO pin configured as an external interrupt configured from CubeMX. The problem I'm having is that it doesn't consistently work out of boot. ...

That's it! I looked at osKernelInitialize, but not MX_FREERTOS_Init (probably got distracted). I appreciate your help!

I updated all my ST tools and still get the same generated code: /* Init scheduler */ osKernelInitialize(); /* Call init function for freertos objects (in freertos.c) */ MX_FREERTOS_Init(); /* Start scheduler */ osKernelStart();No wrapper for user co...

Change the configuration of a GPIO pin in real time

How do I add FreeRTOS threads without CubeMX deleting them?
