I wonder if there are any discovery or evaluation boards that directly support connection to a 10.1" screen, and please do respond with something other than Riverdi. It would be nice if one could develop its own hardware without being overly dependen...

I am running a simple task on the M4 core which I want to clearly separate from the M7 core, which runs the GUI (TouchGFX generated). Since I am only running a single task on the M4 I would not need an RTOS for reasons of functionality. However, I ha...

I have recently bricked my STM32H7 discovery kit by trying to select the M4-only boot option, but I am no longer able to connect the debugger. I have had a similar problem with the Arduino Giga board but I managed to "unbrick" it by running a bootloa...

I am experimenting with an STM32F3348-DISO board. A waveform is generated using the timer TIM6 update event and DMA channel 3 (cyclic mode). At the same time, I am using an ADC to read the same waveform into a dedicated buffer (DMA channel 1), and th...

I am new to STM32 development and I have INCREDIBLE difficulties getting any example to run on any platform. I used to be able to run some very simple examples and even successfully implement changes on a TouchGFX-generated project, but changing the ...

Further to my post I have managed now to call that function from Model.cpp by including#include <touchgfx/Application.hpp>#include <gui/common/FrontendApplication.hpp>and calling static_cast<FrontendApplication*>(Application::getInstance()) ->gotota...

But you would not be able to callstatic_cast<FrontendApplication*>(Application::getInstance())->gotoScreen1ScreenNoTransition();from .c code. How could you circumvent that, could you write a c-calling convention compatible wrapper inside FrontEndAppl...

Switching a screen seems easy on the surface, but the problem is that the above calling convention does not work from C code (for instance if you want to call it form your own task in freertos.c). Unsurpisingly the compiler does not understand a stat...

I have had a simliar problem with my own design, which is based on the STM32H747-disco connection of the SWD. I am almost inclined to believe that the problem is with the VCP of the MB1441B board (aka ST Link V3-Set) and neither the bootloader nor th...

I just wanted to let you know that I have decided to leave my hands of the STM32 for good. I have learned a lot when it comes to low level hardware display interface design but I am just sick to teeth to deal with such a crapy MCU, such as the STM32H...

Running 10.1" LVDS display on (STM32747I-Disco) discovery board

If RTOS is used on an M7 core, does it have to run on the other M4 core as well?

How to run bootloader on bricked STM32H7 Discovery kit?

Can the definition of a HAL_ADC_ConvCpltCallback interfere with the DAC/DMA?

Why is any debug attempt on the STMF3348 discovery board always ending up in the hardware fault handler?
