I use H750VBT6 FMC driver 800 * 480 LCD, due to internal SRAM is less than 800 * 480 * 2, so use PartialFrameBufferManager method.Because there is no TE pin in my LCD module.So I selected disabled when Cubemx generated the Partial Framebuffer VSync option for the project.Check the G071demo and find that the demo USES TE PIN of the LCD module, the edge is triggered and touchgfxSignalVSync() is called periodically.In this case, whether can continue to use PartialFrameBufferManager.If so, how do I call touchgfxSignalVSync() at the software level?Second question, under the condition of my present hardware, user-defined touchgfxDisplayDriverShouldTransferBlock () function, DMA or DMA2D speed delivery data should I use?If anyone has similar demo or *. Ioc, please provide it, thank you.These two issues, I think, are the biggest problems with TOUCHGFX on the H750, which currently has no external SDRAM.:face_with_tears_of_joy: :face_with_tears_of_joy: @Martin KJELDSEN​ 

Hello, working with STM32H753 and wanted to know the maximum gpio speed it could achieve. Have achieved only 50MHz using TIM with PWM .Also can it take input of 30MHz 8-bit parallel data? Is there any specific functionality required to achieve high speed as described in the datasheet?https://www.st.com/resource/en/datasheet/stm32h753ii.pdf

I am using STM32CubeIDE + STM32F103C8T6 MCU with USART1. I am transmitting data by calling this function:HAL_StatusTypeDef HAL_UART_Transmit_IT(UART_HandleTypeDef * huart, uint8_t * pData, uint16_t Size)The function is generated by CubeIDE. It turns out that this call blocks until the last character is sent out. I found that what is blocking is the following line in this function: __HAL_UART_ENABLE_IT(huart, UART_IT_TXE);HAL_UART_TxCpltCallback is called some microseconds before HAL_UART_Transmit_IT returns.Any ideas why this happens? I would expect HAL_UART_Transmit_IT to return immediately, while transmitting the data should be done in the background.

I think programming was successful at first time but after that I get only write protection and reset errors.STM32 ST-LINK Utility and STM32CubeProgrammer complain about reset and write protection.

Hello , New year 2021 Greetings:party_popper: ! Hope you all are doing great !Looking at the FreeRTOS wiki , there is no support for Cortex - A7?Is there an alternate port available for FreeRTOS for Cortex A7? or some customization for the same?what is the recommendation? Thanks and Regards,Have a great Decade !!D

Dear ST Hello,I am looking for a code style for my project. I found this website link below, but this style is quite old "1995". Could you please share with me the code style you know?link: https://ptolemy.berkeley.edu/projects/embedded/research/vis/doc/VisEngineering/vis_eng/node1.html We are looking for certification, The idea is to certify this code by the end of dev.Thank you in advance,S.Tarik

When starting STM32CubeMonitor it displays a dialog reporting "Application server port already in use"; the application then exits when the dialog is closed.In the details it says that port 1880 is already in use; however netstat doesn't show this port as being used. (Windows 10, 64-bit).Any suggestions?Thanks,Simon

Hi, so I'm new to ARM and got a STM32H755 Nucleo board. Using the STM32cubeIDE to auto generate code, I spent hours trying to follow tutorials and get the blink code working until someone mentioned to me that the auto generated MX_GPIO_Init code is a lot shorter than other boards code. The STM32745 is also like this but checking out the 723 and l4 series from youtube videos, they all contain extra instantiation code mine doesn't. This seems like a bug to me and looks like what's causing me not to get a blinking LED with the usual HAL calls, unless there's some other main.c file I'm missing since it's a dual core MCU.This is the only code generated for my MX_GPIO_Init():static void MX_GPIO_Init(void){ /* GPIO Ports Clock Enable */ __HAL_RCC_GPIOC_CLK_ENABLE(); __HAL_RCC_GPIOH_CLK_ENABLE(); __HAL_RCC_GPIOA_CLK_ENABLE(); __HAL_RCC_GPIOB_CLK_ENABLE(); __HAL_RCC_GPIOD_CLK_ENABLE(); __HAL_RCC_GPIOG_CLK_ENABLE();}Thanks for your help.

Hii,While configuring STM32F446RE on CubeMX version 5.0.1 for using the board for reading and writing data on an SD card using SDIO mode (1 bit mode), after enabling this mode and then enabling SD Card option in the FATFS Middleware, it asks me to resolve clock issues and I run the auto-clock resolver, the clock issue gets resolved but when I click on generate code, I get this error message "These IPs still have some not configured or wrong parameter values : [FATFS]". When I try to check what is wrong with the IPs, there is just one option available and I cannot find a way to resolve this error. I click on generate the code anyway. Kindly helpWith regardsSiddharth Soni

I use stm32cubemx 5.5, and there is a problem bothering me.when i enable FATFS in stmcubemx, i got an warning: verify the platform settings tabI know i should add a sd detect pin this warning, but actually, the board don't have the detect pin.although i can ignore this warning, i would like to cancel this warning.So How to cancel FATFS verify the platform settings tab

Newbie here and quite fortunate and unfortunate to use STM32H747-DISCO.For a newbie like me, it is quite overwhelming.I mostly rely on CubeMX to generate code and combine with firmware examples.For STM32H747-DISCO, the generated code is emptly.In CM4 src:{   /* GPIO Ports Clock Enable */ __HAL_RCC_GPIOI_CLK_ENABLE(); __HAL_RCC_GPIOB_CLK_ENABLE(); __HAL_RCC_GPIOG_CLK_ENABLE(); __HAL_RCC_GPIOC_CLK_ENABLE(); __HAL_RCC_GPIOE_CLK_ENABLE(); __HAL_RCC_GPIOH_CLK_ENABLE(); __HAL_RCC_GPIOD_CLK_ENABLE(); __HAL_RCC_GPIOA_CLK_ENABLE(); __HAL_RCC_GPIOF_CLK_ENABLE(); __HAL_RCC_GPIOK_CLK_ENABLE(); __HAL_RCC_GPIOJ_CLK_ENABLE();   }and in CM7 src:static void MX_GPIO_Init(void) { GPIO_InitTypeDef GPIO_InitStruct = {0};   /* GPIO Ports Clock Enable */ __HAL_RCC_GPIOC_CLK_ENABLE(); __HAL_RCC_GPIOA_CLK_ENABLE(); __HAL_RCC_GPIOH_CLK_ENABLE();   /*Configure GPIO pin : CEC_CK_MCO1_Pin */ GPIO_InitStruct.Pin = CEC_CK_MCO1_Pin; GPIO_InitStruct.Mode = GPIO_MODE_AF_PP; GPIO

Hello,as many before I am wondering how to add custom headers to a project generated by TouchGFX. I have read a few forum posts like these:https://community.st.com/s/question/0D50X0000BJ22vx/how-to-manually-add-include-path-to-touchgfx-designerwindowshttps://community.st.com/s/question/0D53W00000TEpmmSAD/how-to-add-nontouchgfx-header-and-source-files-to-touchgfx-makefileI tried to include the header path in the makefile like this (I have no clue on how to code a makefile):is also tried:this is how it looks like in CubeIDE:I want to include the folder LEDs with my two needed headers. Could someone pls write some "Makefile examplecode" on how the include path hast to look like?Also for better understanding, why isn´t simply adding a new header to the project viable? It works for c files but not for headers an it also works for non TouchGFX projects. I simply copied the header code to my declarations before my main function and the functions defined in my c file worked as expected (e.g SK

Recently I have been tasked with developing our companies embedded testing strategy. The task is little bit above me since this is my first job, however I am determined to learn anything I need to and put together a solution that works for the company. The embedded team is small: only 4 of us + 1 electronics team member who is willing to lend a hand in writing software.We are working with STM32 series of MCU with the ST Cube Ecosystem of tools. At the moment the company has no formal testing procedure. We are also short on time & manpower.I have introduced a unit testing framework recently, however it has its weakness (not all embedded code can be tested, maintaining it is harder, just need a single API call HAL then the unit testing framework gets confused.)I have been looking around the web a bit and most people say: yeh we use python to automate our testing of embedded systems etc .... what does that mean, how do you use python scripts to test your system, is there any framework

Hi all,1)in STM32F446xC/E it is written that the memory consists out of 8 Blocks each 512-Mbytes. This leads to 4.096-GB. In PM0214 its written: The processor has a fixed memory map that provides up to 4 GB of addressable memory. Now my question: How much does it have in total, 4.096GB or 4.000GB? Or does it mean 0.096GB are not addressable?2)Is it correct, that some Addresses only refer to 4 Bit areas? Otherwise I cant explain the 4.096GB knowing that the last Address is 0xFFFFFFFF. In the beginning i thought it might be 8 bits per address but that would result into 4,29....GB.Or is there something i got completly wrong?

I have an STM32H735G Discovery Kit and I'm using it with STM32CubeH7 IDE.I want to modify the projects for my own code. Specifically, I want to make a copy of a project.But, I MUST keep the metadata for the toolchain and the debugger. Right now, I can use the STM32 Project Wizard to import sample code, which has the correct settings for the project, including toolchains and debugger targets.Let's say I take a library project from Github, or from the zipfile where Cube keeps its sample code. Let's say it's the LwIP_HTTP_Server, which has almost everything I need to modify it for my own project. I then make a new project that is makefile-based and import the project code.NOTHING WORKS. NOTHING.The toolchain pointers are missing, and the debug target can't be found. CMSIS is missing, and obviously the particular project won't build without any of these things.I can't find any of these things exposed in the menus. There is NO option that I can see to make a "blank" project with the STM32MC

Hi allI am having difficulties adding the CMSIS include libraries in the cube IDE, when I attempt to build the project I am getting error messages about files that are already included in the "path and symbols" -> "includes directory". For example the "arm_math.h" library.but I have already included the CMSIS DSP include library which has the "arm_math.h" file in the "Path and symbols"-> "includes directory" section. as seen here : could anyone help me regarding this issue ?Thanks

Hi all,I would like to know how to use "handleTickEvent" on AnalogClock.I draw a screen with a Analog but thisone never upate itself.I see other examples witch use handleTickEvent to execute a new render but all has the same configurations..The strange thing is that In my code this routine is called for about 10 times only when touchscreen is pressed.this is my code:void Screen2View::handleTickEvent() { tickCounter++;   if (tickCounter % 60 == 0) { if (++analogSeconds >= 60) { analogSeconds = 0; if (++analogMinutes >= 60) { analogMinutes = 0; if (++analogHours >= 24) { analogHours = 0; } } }   // Update the clocks analogClock1.setTime24Hour(analogHours, analogMinutes, analogSeconds); } }class Screen2View : public Screen2ViewBase { public: Screen2View(); virtual ~Screen2View() {} virtual void setupScreen(); virtual void tearDownScreen();   virtual void handleTickEvent(); protected: int tickCounter; int analogHours; int analogMinutes; in

When reading from an SD card using SPI and FAT32 using either f_read() or f_gets() the data returned does not match the actual file contents.I am using an STM32F103C8.fresult = f_open(&fil, "0:test.txt", FA_OPEN_EXISTING | FA_READ | FA_WRITE);   unsigned int bytesWritten = 0; bufclear(buffer, 1024); sprintf(buffer, "test TEST test 123");   fresult = f_write(&fil, buffer, bufsize(buffer), &bytesWritten);   char fileBuf[10]; bufclear(fileBuf, 10);   f_gets(fileBuf, 10, &fil);

EE designed the board with both pins in use and both needing to wake up from STOP2. At start PA5 must be used to awake. Once awake, switch interrupt to PB5 for normal processing. When normal processing is done, switch back to PA5 and enter STOP2. Is there some sample code out there that I can use? Or do I need to reinvent the wheel?

Because I do not have access to the BOOT0 pin (custom board, not eval board) I have used the software method of branching into the bootloader : https://stm32f4-discovery.net/2017/04/tutorial-jump-system-memory-software-stm32/I have adpted this code for the device (notably bootloader address 0x1FF0 0000)USART2 physical pins are PA2 and 3My questions are:Is the bootloader code listening to USART2, is it listening to everything? Or does this require a specific configuration?Do I need to configure the USART2 with baudrate etc. before jumping to the bootlaoder so that it corresponds to the CUBE->UART settings or is this an automatic process?____logs from Cube15:59:33:510 : Serial Port COM34 is successfully opened.15:59:33:511 : Port configuration: parity = even, baudrate = 115200, data-bit = 8, stop-bit = 1.0, flow-control = off15:59:33:511 : No Init bits value is : 0 15:59:33:511 : Sending init command: 15:59:33:511 : byte 0x7F sent successfully to target15:59:34:511 : Wait en

Hello everyone. I am currently working with an STM32F469I-Discovery Board. I created my project using the STM32CubeIDE board selector and made my layout using TouchGFX. Both softwares communicate as it should and I can generate code from one software and see the changes in the other one. I successfully added a task to FreeRTOS so I know I can correctly program the board and that it is working. I also tested an example showing me that the screen is working as it should too.Now comes my problem. I am completely unable to display anything on the screen that has been created using TouchGFX and STM32CubeIDE. I configure the LTDC as well as the DSI in all imaginable configurations and nothing is working.I was expecting it to be rather straight forward, without barely touching anything:create the project in STM32CubeIDE (screen and communication configured by the IDE),modify the TouchGFX file to look as I want,generate the code,built and debug the code in STM32CubeIDE,the display shows up.Do
