STM32 MCUs Products

I am not new in using STM32H7 products but in my last project I can not connect the target by ST_Link.I take care about power supply, pins to connect at GND or 3V3 and so on but the Link-Utility return this error:<<08:28:41 : ST-LINK SN : 440032001500004737364D4E08:28:41 : V2J43S708:28:41 : Connected via SWD.08:28:41 : SWD Frequency = 4,0 MHz.08:28:41 : Connection mode : Normal.08:28:42 : Can not connect to the target!Please select "Connect Under Reset" mode from Target->Settings menu and try again.08:28:53 : Unexpected error>>It seems the comunication start with the target but can not complete it.I Try all possible combinations of the ST_Link Utility configurations not no resultsCan anyone help me to solve this problem?Is there a specific list of pin to connect at 3V3 or GND or with CAPS and so on in order to let the target comunicate properly.Thanks for you suppo

Posted on June 07, 2017 at 11:16I am at my first time with RTC and I have some problems.I would like to configure rtc as a calendar.I would like to retrieve date and time after a certain event.I am following the RTC_Calendar example in the STM324xG_EVAL folder (STM32Cube \ Repository \ STM32Cube_FW_F4_V1.16.0 \ Projects \ STM324xG_EVAL \ Examples \ RTC \ RTC_Calendar) with a discovery.This example freezes in HAL_RTC_Init (if (HAL_RTC_Init (& RtcHandle)! = HAL_OK)).Can you send me a few simple examples (configuration and recovery date and time).Can someone help me? Please.

Hi,I am using NUCLEO-U5A5ZJ-Q board  to setup a USB VCP connection with PC. I am currently using the example project CDC-ACM, and getting a maximum speed of up to 4.4MBPS via the connection by increasing the Tx FIFO  size and Max Packet size in device side example code.  HAL_PCDEx_SetTxFiFo(&hpcd_USB_OTG_HS, 0, USBD_MAX_EP0_SIZE/4); HAL_PCDEx_SetTxFiFo(&hpcd_USB_OTG_HS, 1, 1920); HAL_PCDEx_SetTxFiFo(&hpcd_USB_OTG_HS, 2, USBD_CDCACM_EPINCMD_HS_MPS/4); Since this example is for USB - UART bridge, I have removed the UART part of it and just kept the usbx_cdc_acm_write_thread_entry thread function enabled for sending data to PC. I have written a python script in windows side to receive the buffer.I have attached the file ux_user.h for reference,  And I have increased the memory pool size or the dev

If you need an example, how to use PDM microphones (MICs) on STM32 MCU and how to bring the voice/sound via network to a host computer (PC) - here is my project:https://github.com/tjaekel/PortentaH7_VFR_CubeIDE Here is a YouTube video with a demonstration:https://youtu.be/HZ2tHTENgCg it is based on Portenta-H7 (STM32H747) (with breakout board or using the vision shield), but I post it here because: it is NOT based on Arduino drivers, nor Arduino IDE! It is an STM32 Cube HAL based project, for STM32CubeIDE, a regular STM HW/FW project like a NUCLEO board.What it does (it is a pretty heavy/large project):it uses PDM MICs

I have the Nucleo-H743ZI2 board. It uses the STM32-H743ZI part which has a reasonably fast 16-bit ADC, or at least that’s how it is specified: https://www.st.com/en/microcontrollers-microprocessors/stm32h743zi.html3× ADCs with 16-bit max. resolution (up to 36 channels, up to 3.6 MSPS)When I am testing this board, running the ADC at about 58ksps in single-ended mode, the actual dynamic range of the ADC seems rather low to me. I have the ADC using DMA to fill a circular buffer. Using a 20-second period sinewave input, I see 2000 counts or more between max to min readings in each set of 4000 readings on what should be a nearly-DC value during that short 70 msec interval, only 0.3% of the sinewave period. Even when I use 8x oversampling to average 8 readings together, and actually connect the ADC input directly to ground, I still s

I am trying to run a simple ADC example provided by STM32CubeIDE for my Nucleo-H743ZI2 board.  I know the basic functionality of the board hardware and computer connection is OK, because I was able to write a simple program to blink all three user LEDs (LD1, LD2, LD3) on the board, and that works as expected.However the example code, for which the README file starts as below, does not work. It compiles without error, it loads and it runs, but after some delay it ends up in the Error_Handler code with the red LD3 LED  after the call to  HAL_ADCEx_Calibration_Start() returns 0x01 instead of the HAL_OK = 0x00 value expected. Is there anything obvious I might be doing wrong? The only thing that occurs to me is this example was provided for the Nucleo-H743ZI and not the Nucleo-H743ZI2 that I have, but the latter part number does not show up in any examples, at all so I assumed maybe it was compatible (?) ADC_RegularConv

Eyes rolling back in my head with all the choices for doing STM32 development... need help.I'm trying to setup for embedded processor programming and testing using the STM32 devices... like the STM32H747... for a variety of upcoming projects...and I'm lost in the jungle of options and web links and pages describing this 1,000 bladed pocket knife... and all of its associated stuff...and yes, I've done embedded processor development work before but it has been awhile and I'm trying to catch up with the world as it is today.So thanks to any kind soul for helping me get my initial dev setup and operating.The Question... What specific items do I need for a complete STM32 development system?A - Are these devices all that I need?Nucleo-32 or Nucleo-64 or Nucleo-144 board? B - Or do I need all  this? - Hardware:

Hello, I try to setup a working example of UAC1.0 USB to I2S - stereo 48kHz 16 bits on a stm32F4 discovery card (with CS43L22 CODEC). I try to get the project developed as far as possible on existing code from ST:STM32CubeIDE generated code,The board Drivers/BSP code for the audio part,inpiration from audio stand alone examples from other F4 boards.But this is not working correctly: bit of part of music with cracks and noises. With a Logic Analyser (LA), I looked at the I2S and it is clearly wrong. There are variants, but basically, it stammers. Instead of 0x0000, 0xDE1F, 0x0000, 0xCA... it gives something like 0x0000, 0x0000, 0xDEDE, 0xCACA, 0x0000, 0x0000. Please see attached snaposhots, with buffer content after breakpoint at usbd_audio.c Sync function, and the corresponding Logic Analyser capture. Values correspond between with Dec=> Hex conversion, except the "stammer".

I am starting a project in which I need touch sensors. With the help on chat gpt I have come up with this code. while (1){key = HAL_TSC_GroupGetValue(&htsc, TSC_GROUP1_IO2);printf("%d\n",key);/* USER CODE END WHILE *//* USER CODE BEGIN 3 */}I have sampling on group 1, I01 and the sensing on group 1 IO2. I have connected the sampling IO1 to GND pin and the IO2 I have left in the air for me to touch (wire). The problem is that whatever I do, I get printed out value of 0. Thank you for your help.

I am developing using the STM32H series, but LL_SPI_IsActiveFlag_EOT does not go high during spi4 communication.

Hello Team ST, I am working on ADC setup using DMA, where upon the conversion completion the ADC values shall be transfered to memory using DMA. The ADC and DMA configurations are as shown in snap below.The DMA settings are as follows.The initialization sequence and the ADC sta

Hello.I want to integrate ADC with DMA, and calculate the average count of all convertions.I'm using the following code:In adc.c:```if(HAL_ADC_PollForConversion(&hadc1, 10) == HAL_OK) {uint16_t value = HAL_ADC_GetValue(&hadc1);USART_Send("%.3f", value);HAL_ADC_Start(&hadc1);}```In main.c:```HAL_ADC_Start_DMA(&hadc1, (uint8_t*) AVG_BUF, AVG_BUF_SIZE);``` However HAL_ADC_GetValue() seems to not use DMA.I want it to explicitely use DMA to read.

During the process of configuring option bytes, we unfortunately got few MCUs bricked (unresponsive). In these devices, i was getting the following errors when trying to flash using STM32 programmer. (Tried both GUI and CLI with various reset modes and frequencies). All attempts resulted in the same error as shown below.Error: No STM32 target found! If your product embeds Debug Authentication, please perform a discovery using Debug AuthenticationCould you suggest a way to recover these devices from the bricked state?For your information, these were the option bytes configuration done along with the Flash unlock/lock sequences during runtime 

Hey!I'm stumbling around with integrating littleFS using STM32 HAL library and EMMC 4GB chip, and any help would be greatly appreciated.I modified FATFS EMMC example so that it uses littleFS. I changed nothing in the SDMMC driver, so since it worked with original example I'm expecting it should also work with littleFS.I'm using STM32L4P5G-DK development kit with EMMC chip: Block size is 512 bytes and number of blocks is 7634944.The issue here is that I cannot for the life of me get it to work reliably. When I somehow (by tweaking parameters) get it to work and I change one parameter, it fails to format and then even if I reverse the changes the same issue persist.I would really appreciate if somebody could help me by checking the configuration and functions. Thank you so much!  

Hello. I am developing CAN communication protocols using STM32F429.However there is a problem in sending CAN frame data. Here is a picture which I captured in CAN TX using logic analyzer, and as you can see, the series of data is losted after first data.I tested this with publishing 100Hz, this problem occurred once a minute.In normal case, it should be like this.

 

Hi! I've seen some tutorials on can communication and notice that each of them use different StdId's. I'm using two nucle-l433rc-p boards, do I need a specific StdId or will any number between  0 and 0x7FF suffice?  

Hi,uC: STM32G051K8U6, IDE: 1.14.1, MX: 6.10.0-RC9I tried to generate some low frequency timeout using the LPTIM1 and the internal LSI time source, but it seems the code generator doesn't take in account the chosen option in the "LPTIM1 Clock Mux" selector. It seems it always choses the first option, whick is PCLK. I confirmed this, generating the code with different options selected and comparing then using WinMerge. Nothing in the code changed. After some searching, I found this function was responsible for initialising the clock source:void HAL_LPTIM_MspInit(LPTIM_HandleTypeDef* hlptim) { RCC_PeriphCLKInitTypeDef PeriphClkInit = {0}; if(hlptim->Instance==LPTIM1) { /* USER CODE BEGIN LPTIM1_MspInit 0 */ /* USER CODE END LPTIM1_MspInit 0 */ /** Initializes the peripherals clocks */ PeriphClkInit.PeriphClockSelection = RCC_PERIPHCLK_LPTIM1; if (HAL_RCCEx_PeriphCLKC

Is there any chance to use both OCTOSPI (as 2xQSPI) with a LQFP100 package? There is a OCTOSPIM_P2_NCS but no OCTOSPIM_P2_CLK and Multiplexed Mode is not possible (only on P/Q-variants). Thanks in advance! 

Hi all,i am performing some 400bytes blocks transferts by SPI, at 16Mhz.I have NSS off, so no CS up/down between frames.From some testing, whatever system clock i set, or whatever spi clock i set, there is a fixed 4us time between 2 consecutive frames. This pause is of course very visible and heavy at 20Mhz spi clock, by scope something like:__||||||||_____________||||||||______________|||||||_____Transfer is done by LL_SPI_TransmitData8If any help to reduce this delay between frames, would be very good, or at least to know i cannot reduce it in any way will be helpful too.thanks a lot  

STM32H573AII3Q is a 169 pin UFBGA SMPS package. Along with SMPS option, does it also have internal LDO for core supply? Can we use internal LDO to supply core voltage for this package?

I am having some issues implementing dual bank/boot.I have set up a dummy project starting at base address 0x08000000 for 256k bytes that will turn on a red LEDI have another dummy project starting at base address 0x08040000 for 256k bytes that will turn on a green LEDBased on the example from 474 Dual Boot Mode, it seems you set the system in DBANK mode by setting the bit in FLASH_OPTR as well as setting the BF2B bit.Now I am confused if the BF2B forces booting from bank 2 or it just means it is allowed, cause I also see the function HAL_SYSCFG_EnableMemorySwappingBank(); // stm32g4xx_hal.c line 591Does calling this function and setting the SYSCFG_MEMRMP_FB_MODE bit cause the swap? or is this bit used to show where you booted from? right now I call this, and it crashes at HAL_FLASH_OB_Launch(), I do see dbank bit is set but never the BF2B bit or the SYSCFG_

After about an month, I connected my NUCLEO-L4A6ZG to my PC again. STM32CubeIDE nor the STM32CubeProgrammer can't recognize my board. I already tried different USB ports and different USB cables.When Trying to run a program the Error Message in the IDE is "No ST-Link detected! Please connect ST-Link and restart the debug session." and in the Programmer "Error: No debug probe detected". My board is powered on but seemingly not recognized. The red LED is constantly blinking (red-off-red-off-...). The green LED is constantly green.In case it required, my OS is Linux Mint (switched it from Fedora within the mont

Hi, I am wondering if anyone has any experience with HAL SPI as when I try in 16-bit mode to make a single packet of data manually and use (sizeof xxx) it sends 2x data packets to the oscilloscope and when I specify the packet size as "1" I get the correct waveform? I show it below the code and attach the scope readings:-uint16_t packet;packet = 0b0111 1111 1000 0000;  // send 8 MSB bits in 16 bit modeHAL_SPI_Transmit (&hspi1, &packet, sizeof(packet), HAL_MAX_DELAY); // sends 2 packets?HAL_SPI_Transmit (&hspi1, &packet, 1, HAL_MAX_DELAY); // sends correct 1 packet.
