STM32 MCUs Products

VSCode is gaining in popularity at work and so I had a requirement to use it as the development platform for an ST mcu based project. I have very little experience with vscode and as I was unable to find an answer to my problem I thought that I would share what worked for me.My application uses both internal and external flash for code (qspi). I created an external loader (MT25Q128A_STM32F746_KAL_AB.stldr) and was able to program this in STM32CubeIDE by configuring the external loader details in the debugger tab. VSCode requires certain extensions - cortex-debug; MemoryView; Peripheral Viewer and RTOS Views. Sorry if I've missed any.The way to debug the application is to create a launch.json file. Below is mine. Hope it helps{// Use IntelliSense to learn about possible attributes.// Hover to view descriptions of existing attributes.// For more information, visit:

Hello,upfront, it might be an incredibly dumb problem on my behalf as I am fairly new to this.For a couple days now I have been trying to read out the voltage through the onboard ADC configured for 12 bits but all I am getting back are values in a similar range (mostly somewhere in between 1500 and 1800 but that changes with the amount of delay that I introduce, does that help?). The value itself does change, floating within that range.I have tested for faulty connections and switched the board but the issue persists.It is a very basic setup, just a potentiometer connected to the A0, and it works if I use an Arduino with its framework to try and read the value (the potentiometer is not broken). But also supplying A0 with ground or 3.3v directly doesn't change the read value. After reading the value I write it to serial, which is also working.My guess is that something with my clock configuration is wrong and the ADC has not enough time to run a mean

Hi community,I am using STM32H747I-DISCO board and I configured external SDRAM as dynamic data memory in M7 core by  calling the SystemInit_ExtMemCtl() function in  SystemInit() function, it is working fine but when I tried with the M4 SystemInit_ExtMemCtl() function call is only defined for M7 core in SystemInit() function. Please someone suggest is it possible to use external SDRAM as dynamic data memory in M4 core? 

Hi, everyone.When implementing a sort of delay function using Timer2 to have a more precise time control, while putting the MCU in power-saving mode, I noticed that the division performed to the APB1/2 clocks does not correspond to what's programmed. See below a short description of what I observed:RCC->CFGR |= (RCC_CFGR_PPRE1_DIV1 | RCC_CFGR_PPRE2_DIV1);    //No division, as expectedRCC->CFGR |= (RCC_CFGR_PPRE1_DIV2 | RCC_CFGR_PPRE2_DIV2);    //No division, expected by 2RCC->CFGR |= (RCC_CFGR_PPRE1_DIV4 | RCC_CFGR_PPRE2_DIV4);    //Divides HCLK by 2, expected by 4RCC->CFGR |= (RCC_CFGR_PPRE1_DIV8 | RCC_CFGR_PPRE2_DIV8);    //Divides HCLK by 4, expected by 8Meanwhile, I noticed that on the .ioc file the frequency at the output of the APB1 Prescaler gets multiplied by two if this prescaler is greater than 1 (2, 4, 8 or 16), as shown

Hello, we are using the saleale logic 8 to read data transfer between an STM32 MCU and an IC through SPI (ADS8166 ADC).The CLK frequency is 1.5 for the SPI configuration with a prescaler of 2 so at the end we have  CLK of 750 kHz. For some reason SOMETIMES we can't read the data properly through the MISO channel with this configuration, even though the saleale has a sample frequency of 50 Ms/s. The saleale configuration is correct and the MOSI signal is always read accordingly. The debugger always reads the correct values so the data being transfered is correct but the saleale reads it wrong. Find attached screenshots of the measurments.Any idea of what could we be doing wrong?should be reading 0xAA:

I am currently working on a project that requires the use of IAT EWARM 8.50. When I compile this project for an STM32H745XI MCU and try to flash/debug I get the "Failed to load Flash loader" error. On the flash console I get this output:C:\Program Files (x86)\IAR Systems\Embedded Workbench 8.4\arm\config\flashloader\ST\FlashSTM32H7x5.mac(169,34): Error: Operation error.At that location (169,34) in the macro file I find:DBGMCU_APB3FZ1 = __readMemory32(0xE00E1034, "AP2_Memory");And column 34 is at the start of the first argument for __readMemory32. I have tried a few different settings while debugging and unchecking the 'override default .board file'Also, This process works on the built in stlink v3 for the STM32H745 Nucleo board and for the STlinkv2. Has anyone seen this problem before?

Posted on July 24, 2015 at 16:37Hello everyone.I am using a custom board with STM32F030C8 on it and ST-Link V2 for programming and debugging on keil MDK v5.14.It worked fine and i was able to burn and debug the firmware. Yesterday i programmed an example from STM32 standard peripheral library, i was successful to program the controller first time. But the next time i try to flash the code, it throws an error ''No target connected''. I dont know but somehow it bricked the controller. The same thing happened with the other perfectly working board. And now i have 2 bricked boards.Is there any way i can find out if the controller is working?Because i am not able to detect it using keil or STlink visual programmer.I am very new to STM microcontrollers...Somebody plz help... #stm32

Hi, I am using STM32H747I-DISCO board, I configured FDCAN it is working fine in M7 core but the same code is not working in M4 core , I changed the FDCAN initializer from M7 to M4 core in STM32CubeMX. Here is my FDCAN initialization. /* USER CODE BEGIN FDCAN2_Init 0 */   /* USER CODE END FDCAN2_Init 0 */   /* USER CODE BEGIN FDCAN2_Init 1 */   /* USER CODE END FDCAN2_Init 1 */  hfdcan2.Instance = FDCAN2;  hfdcan2.Init.FrameFormat = FDCAN_FRAME_FD_NO_BRS;  hfdcan2.Init.Mode = FDCAN_MODE_NORMAL;  hfdcan2.Init.AutoRetransmission = ENABLE;  hfdcan2.Init.TransmitPause = DISABLE;  hfdcan2.Init.ProtocolException = DISABLE;  hfdcan2.Init.NominalPrescaler = 5;  hfdcan2.Init.NominalSyncJumpWidth = 3;  hfdcan2.Init.NominalTimeSeg1 =

In STM32L4Q5VGT6, GPIOx-> ASCR register is missing in reference manual of RM0432 Rev 9. ASCR  GPIO analog switch control register,   Address offset: 0x2C (GPIO_TypeDef)To enable the GPIO to ADC switch using the register ASCR is LL_GPIO_EnablePinAnalogControl is missing in STM32L4Q5VGT6. But it is STM32L475VGT6 ASCR register is available, why in STM32L4Q5VGT6 it is left out. Is it any alternate register available for the same purpose.

Hi all i'm implementing a serial communication between my evaluation board and my PCi managed to send data from my board and read it via PuTTY.but when i run HAL_UART_Receive_IT and send messages via PuTTY it doesnt trigger the "HAL_UART_RxCpltCallback" Functionim using NUCLEO H743ZI2and USART3 baud rate: 115200Interrupt is enabled for USART3This is my code (just the important stuff):Thanks! :)void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart) { char str[100]; strcpy(str, "hi hi\n\r"); HAL_UART_Transmit(&huart3, (uint8_t*)str, strlen(str), 1000); } int main(void) { char str[100]; strcpy(str, "hello hello\n\r"); HAL_UART_Transmit(&huart3, (uint8_t*)str, strlen(str), 1000); HAL_UART_Receive_IT(&huart3, rx_data, 6); while (1){} }

I purchased the STM32F746G-DISCO in the hope of being able to read and write to an SD card.I followed the guide below...https://community.st.com/t5/stm32-mcus/how-to-create-a-file-system-on-a-sd-card-using-stm32cubeide/ta-p/49830 However, when stepping through the code I can see it is going to the Error_Handler when the function f_mkfs is called...  if(f_mkfs((TCHAR const*)SDPath, FM_ANY, 0, rtext, sizeof(rtext)) != FR_OK) { Error_Handler(); }   I have tried two different SD cards:1. Kingston 16GB microSDHC CL10 2. Transcend 2 GB MicroSD Micro SD Card, Class 30 (TS2GUSD)When reading the comments at the bottom of the guide, I noticed that others also had t

Hi,I don't want to over step the mark here and abuse the community so I wanted to ask if it would be ok to ask this question or not. I am looking to kick-start a hardware project using an STM32 and being someone who also has a big day job commitment myself, I wanted to find out if there is anyone who might be willing to give me some hours of their time using remote tool ilke Zoom, for mentorship/guidance/experience kickstart as I ramp up my knowledge of the STM32 platform.  I am not looking for free or cheap here, I am very willing to pay someone for their time. Would posting details about what I am after, and asking such a question be an appropriate use of this forum, or would I be overstepping the line here for this community?Thanks,Gerry

We've chosen STM32G0+ and STM32H7 microcontrollers for our product development. We seek assistance from ST regarding a Static Code Analysis tool. Could you please provide us with information based on your recommendation?Thanks,Gajanan Maske

Hi everyone,The MCU on my custom board is an STM32U585. I put RDP mode to 0.5 in order to debug the product application with CubeIDE (our custom bootloader is in secure world).RDP regression to level 0.5 works fine (non-secure memory is fully erased (and not write protect) and RDP byte value is 0x55), I can read internal flash on non-secured address but I can't write nothing inside non secure memory (using CubeProgrammer v2.15.0 I try both to write single byte and write a binary in Reliable an Fast connection mode). I can only connect the stlink probe in "hot Plug" Mode. In all other mode I’ve got the error message: “DEV_TARGER_NOT_HALTED).Can someone help me? ThanksHave a good day.GRANGE AurélienPS : I can't sned the source code of secure part.

当我通过 stm32 的 OSPI 使用 OctalRAM（IS66WVO16M8DBLL） 时，我只能读取 ID rigister 和 CFG rigister，但不能写入 CFG rigister。我希望你能给我一些技术帮助。我附上了密钥代码。PSRAM的数据表：https://www.issi.com/WW/pdf/66-67WVO16M8DALL-BLL.pdf

Hi,I configured the TIM17 as "Output Compare CH1 CH1N" with "Toggle on Match mode". The CH1 signal is correct but there is no CH1N output at all. The source codes are listed below. Any comment? Thanks.The initialization call:if(HAL_TIM_OC_Start_IT(&htim17, TIM_CHANNEL_1) != HAL_OK){Error_Handler();}and the Init function:static void MX_TIM17_Init(void){TIM_OC_InitTypeDef sConfigOC = {0};TIM_BreakDeadTime

Hallo there,I use HRTIM_MASTER to retrigger HRTIM A,B;C and to trigger ADC. This works fine.Each of slave timers generate PWM signals. I works also good.As the data from ADC is ready I do recalculation of PWM duty for all 3 channels. And there is an issue.Shadow registry and update on counter reset (bit TxRSTU) should be executed only if all three values are ready. Sometimes I get faulty PWM because third PWM value is not recalculated but gets updated together with first already calculated duty for A and B.How can I implement double condition of shadow update: once as all 3 dury are new calculated and on counter reload (to keep PWM cycle consistency).

Hi, I have STM32F103 and STM32F411. I have successfully made HID mouse on STM32F103, but when I try to make the same on STM32F411, the mouse does not work: "(Code 43) A request for the USB device descriptor failed".What could be the problem?The code/configuration is simple I just enable:Connectivity -> USB_OTG_FS -> Mode: Device_OnlyMiddleware -> USB_DEVICE ->  Class for FS IP: Human Interface Device class (HID)Everything else is kept default.Is this because STM32F103 has micro USB and STM32F411 has type-c? Does type-c need additional settings which I am missing?

Hi everybody.I have a sdcard code which sd buffer is placed at axi ram of mu and handle by m4 core.When m7 cpu data cache is enabled the code doesnt work on m4 core when not using debug, but it works when debugging cores.If its mpu problem it shouldnt work in dubug mode either.I tried defining axi ram as non cachable but problem still the same.

This forum is great, but relies on volunteers to help out. In a commercial environment were time is money, the forum is not an ideal solution in order to get fast assistance to help solve development issues.I am looking for on demand STM32 commercial development support, usually for single specific bugs. So a solution were I can offer a reward to get the bug solved quickly would be great.Any suggestions?

In 50% of the PCB s where the STM32f303 (with the Y revision ) was in we were unable to code a program , as well as that problem we had some difficulties with the UART It won’t connect to the laptop, it says that the device is unrecognizable and that it does recognize the COM port.In the picture down below you can see the unstable signals (they are marked)

Suggest a cam module suitable for stm32h743 Nucleo board, and I want a to monitor my motors and workspace, suggest me a suitable display. I am working on a project that pick and place objects by detecting them using computer vision. It will be helpful to me if you suggest me about components. 

Hello, I'm driving LED driver chip (MAX16836ASA+) with PWM output of microprocessor STM32F303CB.The issue: When turn the Power supply ON, LEDs blinked for a few moments (milliseconds).I assume that the PWM giving some output values (not zero) before the microprocessor is fully set and start operating.Is there any options How to set PWM that default state is Zero (between Power Supply ON and microcontroller normally operating state)?Thank you a lot,Domen

I bought a Stm32f407vet6 board yesterday and wanted to run ardupilot firmware on it. So I tried to put firmware in DFU mode by putting boot0 pin high and boot1 pin low, but for some reason I was not able to do that (my mistake). Then I tried to put that firmware by the stm32cube programmer, and I was able to put the firmware, but it was not working properly, so I did a full chip erase by stm programmer. Now my laptop is not recognizing my stmboard, and I think I erased my default bootloader also. Can you guys help me to know how I can restore it to its default state (factory setting)?Thanks in advance.
