STM32 MCUs Products

Hi,Im new to stm forums so sorry if i make any mistakes.Im using a stm32f103RET6 since i am familiar with f103 and i need usb/other peripherals. Thus far everything works great. However...Im trying to offload some work from cpu to DMA by sending a premade array to the timer, it works fine for the most part except if the very first bit of the transfer (the first DMA byte) is a 1, due to an issue the pin after going high as expected in the same period it goes low and high again when it it not asked, thus confusing the ic's interpreting it as 2x 0bits.If that is unclear i attached a screenshot showing the dip. Some things i made sure of/tested already:- It is not a hardware issue, i designed the pcb myself and the trace to the first led is very short and away from any other digital line- I disabled all other code/generated a minimum POC and the problem persists- The period/baud is set and never modified by the code- I do not change th

So, I'm trying to read data from a dht11 sensor. In the datasheet says that you have to send high signal, wait 80ms, then low signal, and dht11 will start sending data.My problem is, I don't know how to debug this. I don't know how to see if I my sensor is sending me data. How can I see this using STM32Cube IDE?

Hi,I'm having trouble getting PWM output on my STM32F303. I'm using CubeMX for pin config, then generating for Make for use with VSCode on Ubuntu. TIM1_CH3 has been configured for PWM output on PC2, and TIM1_CH2 on PC1. CH2 works as expected, while CH3 seems dead as a doorknob other than picking up some noise from CH2. Same config for the two channels (could they even be different?), and I'm calling the starter functions as follows, shortly after the CubeMX-generated init function:   HAL_TIM_PWM_Start(&htim1, TIM_CHANNEL_2);//MTR2 HAL_TIM_PWM_Start(&htim1, TIM_CHANNEL_3);//MTR2  Any reasons for this to be happening? I noticed quite a few people have a problem with TIM1_CH3, but they always seem to do the initialization themselves, which I figured MX would do for me.

My question might sound "strange" for HW experts.My STM32U5A5 MCU has DCache (16KByte). Datasheet says: used when external memory is connected (e.g. NAND/NOR flash, OCTOSPI).DCache is not used for internal memory (when running from MCU flash or internal SRAM, obvious: not needed, internal SRAM seems to be with same speed as MCU = no DCache needed).But: 16KByte of memory is provided in chip as DCache:How could I use this memory without any external memory device used, not connecting external memory?16KByte, provided as DCache, would give me an option to place the stack region on it (large enough).So, the "idea" is:There is not any external memory connected.But I enable DCache and I read/write via the intended base address (for external memory).I use the MPU and configure in a way, that this base address is a "write-through" regionI mean

It has been asked several times, however I can not find a working solution for me.With STM32L486RGT6 I achieved to implement jump to bootloader, entering DFU mode successfully. All fine!Doing it similar for STM32L071CZY6TR and STM32F469VE it does not remain in bootloader, but starts the application from flash. Environment: Boot0 = 0 fixed. Application is stored in Bank1.Debugging STM32L071 I see the jump to 0x1ff0’0510. Stepping forward ends up in a small loop. Disconnecting the debugger, the application starts from flash. I don’t see any Hardfault message. Do I miss something to reset or should this anyway not be used to update the FW in Flash?Below the code I use.  void Jump2StInternalBootloader(void) { volatile uint32_t addr = 0x1FF00000; HAL_UART_DeInit(&huart1); HAL_UART_DeInit(&huart5); HAL_ADC_DeInit(&hadc); HAL_I2C_DeIni

Hello tinkerer,i am working with the Stm32Wb55 and trying to send data via Bluetooth, unfortunately when i run or debugg my code, most of the time i lose after 30 seconds the connection because the GATT procedure issues a timeout. In terms of the read property i found a solution with aci_gatt_deny_read() but it only works on read and it does not help me further with write.I am looking for a solution where i can avoid to get disconnected while my program is running, so i can comprehend my code better. Is there a possibility to avoid the timeout after 30 seconds or have you other ideas to solve the problem.best regards Alex

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

I'm trying to migrate a project from HAL back to SPL as it's less of a haul than porting our code I have to integrate to HAL. The HAL program compiled but at some point during my porting process I'm now getting link errors ONLY for _fstat and _isatty, not any of the other functions defined in the assert.cThe assert.c is the same between a working SPL based project we have and the new one I'm creating, so nothing has changed there. If I implement _fstat in my main.c it still complains that it can't link.Linker Error:c:/program files (x86)/gnu arm embedded toolchain/10 2020-q4-major/bin/../lib/gcc/arm-none-eabi/10.2.1/../../../../arm-none-eabi/bin/ld.exe: c:/program files (x86)/gnu arm embedded toolchain/10 2020-q4-major/bin/../lib/gcc/arm-none-eabi/10.2.1/../../../../arm-none-eabi/lib/thumb/v7e-m+dp/hard\libg_nano.a(lib_a-fstatr.o): in function `_fstat_r':fstatr.c:(.text._fstat_r+0xe): undefined reference to `_fstat'I've also tr

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.
