I use spc58nh-disp board.​Import board is SPC58xHxx_cut2. ​how to use eeprom or flash memory....where is example?

Is STM32G030C8T6   a 10-year life commitment? How long does it live?

STM32H743i-EVAL, using 2.1.0 PACK, and H7_V1.11.0 firmware.The error occurred after adding NetXDuo > Addons Web Server. I found to satisfy the compile errors that I also had to check (include) Addons DHCP Client and go back to RTOS ThreadX and check PerformanceInfo since there is a routine deep in the app_netxduo.c that needs to use performance information. After this I am left with one error, a multiple definition for CHAR *pointer used in app_threadx.c to keep track of byte_pool allocations when creating threads for threadx and CHAR *pointer used in app_netxduo.c to keep track of byte_pool allocations there when creating the netx threads. Neither of the CHAR *pointers are declared as external nor is there any declarations made in the h files with respect to these variables that might cause a multiple reference.I guess I could go in and give them a unique name, but I thought each declaration should be local to the file it is declared and used in.

I have created an application using CubeMX inside CubeIDE and setting the ThreadX memory pool size in CubeMX sets the value generated in the app_azure_rtos_config.h. CubeMX also generates app_threadx.c and app_thread.h, but in app_threadx.h most examples show a #define APP_BYTE_POOL_SIZE inside the USER CODE BEGIN PD section.Should these values in two different places be the same?And should this be best accomplished by including app_azure_rtos_config.h in the app_threadx.h file and defining the APP_BYTE_POOL_SIZE as TX_APP_MEM_POOL_SIZE with a #define?

Evaluation Board STM32H743i-EVALExample from STM32H735G-DK - NetXDuo - Nx_WebServerAZRTOS-H7 V 2.1.0I am trying to build a Nx Webserver like the one referenced for the H743i. I have begun with trying to set up the memory as it is configured in the 735G example since the memory layout between the two processors is the same. I have not ported any other code yet. I set-up the CubeMX parameters for the same as the 735G .ioc. I have compared the code generated with the main.c code in the example and it is a match. It looks like this: void MPU_Config(void) { MPU_Region_InitTypeDef MPU_InitStruct = {0};   /* Disables the MPU */ HAL_MPU_Disable();   /** Initializes and configures the Region and the memory to be protected */ MPU_InitStruct.Enable = MPU_REGION_ENABLE; MPU_InitStruct.Number = MPU_REGION_NUMBER0; MPU_InitStruct.BaseAddress = 0x0; MPU_InitStruct.Size = MPU_REGION_SIZE_4GB; MPU_InitStruct.SubRegionDisable = 0x87; MPU_InitStruct.TypeExtField = MPU_TEX_LEVEL0; MP

Say we have a STM32 project called Foo. When it is compiled, it generates an intel hex file called Foo.hex that we can use to upgrade the file in the field. That is easy. What we would like to do as add the version say 10.1 or 10_1 and the last 8 digits of the git hash. And the number of compiles since the last git commit to the file name. We can do that; So we commit say version 10.1 with the last 8 digits of the commit being 63245699.We want the name of the file to be Foo10_1_0_63245699.hex. And when asked for the version over I2C the Foo program provides 10_1_0 or 10_1_0_63245699. If the file on the computer is a newer version than on the STM32 board, we activate the boot loader and update the software over I2C. (That part is working) .If we compile the program again, the name adds 1 to the number of files since last commit. so the name changes to Foo10_1_1_63245699.hexIf we compile again Foo10_1_2_63245699.hexWhen we commit we up the version and the number of compiles since the las

Hello,I'm trying to read the pulse counter with a timer on STM32H747. The counter produces pulses up to 100KHz on one timer channel and high \ low signal to define the direction.I tried two approaches.Reference manual says, as I understand, that such signals are supported out of the box. Section 40.3.22 says "To select Encoder Interface mode write SMS=‘001’ in the TIMx_SMCR register if the counter is counting on TI2 edges only, SMS=’010’ if it is counting on TI1 edges only and SMS=’011’ if it is counting on both TI1 and TI2 edges." But setting it to TI1 only mode still behaves as TI1 & TI2. So, it reads quadrature signal, not pulses.Then I tried to use the timer in counter mode. It didn't work for me.My questions are: does encoder mode supports pulse + direction signal, and is there a good example of using a timer in counter mode (mode 1)?Thanks.

I am having an issue similar to https://community.st.com/s/question/0D53W000027iXpbSAE/spi-dma-configuration-generated-by-stm32cubemx-does-not-work but with the SDMMC peripheral rather than SPI.I have an STM32CubeMX project targeting the 32F746GDISCOVERY with the following relevant peripherals and settings:SDMMC SD 4 Bits Wide busSDMMC1 global interrupt enabledSDMMC1 bidirectional DMA request enabled on DMA2 stream 3FatFS enabled with DMA templateWith the above STM32CubeMX configuration and the minimum working example below:#define TEST_DATA_SIZE 32768   // -- snip   static FRESULT fatfs_err; static const unsigned char test_data[TEST_DATA_SIZE] __attribute__ ((section (".dtcm"), aligned (4))) = {0}; static unsigned int bytes;   // -- snip   int main(void) { // -- snip   fatfs_err = f_mount(&SDFatFS, SDPath, 1); if (fatfs_err != FR_OK) { printf("failed to mount card, code: %i.\n", fatfs_err); if (fatfs_err != FR_NOT_READY) { printf("exiting.\n"); exit

I want to distribute to others Dashboard only without designer.Can it be distributed runtime form?

Why am I seeing the warning:Invalid project path: Missing project folder or file: /STM32H743-EVAL-Utils/ThreadX for Source path.the source folder the warning is complaining about is not visible while browsing the project folder. It is not visible when trying to create the source folder using the new source folder tool. If I try to create a source folder named ThreadX, new source folder tool will not allow the new folder because it claims a folder by that name already exists. But using the browse feature within the new source folder tool to see all the current source folders does not show ThreadX. I went so far as to look for any references in the project properties and find nothing that references a folder ThreadX except the treadx subfolders in the Middleware source tree.the only reference I could find is in the .cproject file, where under the tag <sourceEntries> there is the entry:<entry flags="VALUE_WORKSPACE_PATH|RESOLVED" kind="sourcePath" name="ThreadX"/>Removing this

HiSTM32H7A3VG is one of the few stm32's who fit my requirements. This is however sold out on most platforms. Can some one comment on that? Is this chip still in production at all?

In TouchGFX 4.20 designer my pages mostly have default 7200 canvas buffer size but some pages default canvas buffer size seems 0 like below;If I do not add a canvas size to these pages manually, this causes errors. Why does this happen on some pages and not on others?Thanks.

Dear all,May I know where I can download the STM32L476 Discovery source code please?Thanks.

 Hello,The input 1 and input2 signals will be fed from an STM32 but the problem is the signal sent from STM32 is 3.3V but the input to the IC is 5V. How do I convert the same? Please help.

Hi i am using ISM303DLC sensor could you please suggest me which library i have to integrate to get the Roll, Pitch and Heading.

i try to crash my code to check the watchdog timer is reseting the code or not. for crashing my code i use timer interrupt. i.eTIM2_IRQHandler(){---------------;---------------;}TIM_IRQHandler() instead of TIM2_IRQHandler . so, code will be crash at that time watchdog timer should reset the my code and some Exception Handler is there.Example,1)Hardfault2)MemManage3)BusFault4)UsageFaulthow to make my code stuck in an exception handler.

I want to trace ContextSwitchIn and ContextSwitchOut events. I defined two functions for this. #define traceTASK_SWITCHED_OUT() getTASK_SWITCHED_OUT_EVENT(pxCurrentTCB) #define traceTASK_SWITCHED_IN() getTASK_SWITCHED_IN_EVENT(pxCurrentTCB)I put the two functions at the end of the FreeRTOSConfig.h file. But, It is returning to the original file after clean-generate the code again.It says in the help that patching mode only works on lib/src, lib/include and lib/rsc folders.FreeRTOSConfig.h is located in the cfg folder. How can I solve this problem? 

Hi, I have updated STM32CubeProgrammer to version 2.12.0 and our custom External Loader is not load properly anymore. In the EL section I can read "Error: Flash loader error parsing fail" and in the log I can read "Error: Flash loader 'C:\*****/MyExternalLoader.stldr" cannot be loaded."In 2.11.0 it worked just fine.Do I have to change anything in my EL project (Dev_Inf.c, Loader_Src.c, linker.ld...) to work in the new version?Thanks in advance.Dario

Hello,I am using the STM32H7B3LIH6Q with a MX25U51245GMI00 flash memory. The flash is only capable of using Quad SPI, not Octo SPI. If I wanted to use it, do I just use the Dual-Quad SPI mode in CubeMX to utilize it? Or would it not work at all?Also, is Data Strobe only a feature for Octo SPI? Thank you in advance.

After IIC module is initialized, when I prepared the data and to write the IBCR register to send it, after the register is written with the value 0x70(master mode, tx mode, interrupt enable and generate START condition), the value read from the IBCR is 0x50. Who can tell me what's wrong?Thanks!

Hello everyone.I have a custom board based on micro STM32F469NIH6I am using TouchGfx successfully and have all my images stored in a memory mapped 64MB QUADSPI.I would like to give the user the possibility to change some images (for example a logo) and I would like to store these images in an SDCARD.It's possible to do it?That is, is it possible to have the QUADSPI as ExtFlashSection and at the same time have only a few images on the SDCARD?For speed reasons I already use the bitmap cache.How can I load the bitmap stored in SDCARD, in my cache and in what format should the bitmap stored in SDCARD be?Thanks in advance to all who will help me.

Hello, I ported the porting example to a different processor. The self tests are enabled and initialization passes. However I'm not able to read a tag. Logic captures (Salae) are attached. I've verified that I'm receiving interrupts and processing them. I also tested this hardware with an externally NUCLEO-L476RG board and off the shelf firmware and it could read the tags fine. Tags are very close to the antenna, within 1cm. I noticed that when a 14443 tag is present, the number of interrupts increase, from about 15 per second without a tag, to 20 per second with a tag. But it never outputs the UUID of the tag itself. In the captures I observed that the interrupt gets serviced in about 20uSec.Other than the platform files I tried to duplicate the demo firmware as closely as possible, leaving all the technologies enabled, not using ST25R_COM_SINGLETXRX, etc.Thanks,Derek
