I am trying to read a square wave, or rather I am trying to detect when a square wave is falling using the Nucleo-F746ZG board. Using CMSIS v2, using STMCubeIDE 10.1The square wave comes from a flow sensor, and every time it goes from high to low an interrupt is supposed to increment a value within the program.in the .ioc file I have set up a pin and an interrupt, the pin is called FLOW_SENSOR_Pin, and the interrupt is called FLOW_SENSOR_EXTI_IRQn. For reference the pin is the PG3 pin. I have checked the signal with an oscilloscope and the sensor works as intended. The code compiles and is downloaded to the board without problems, though the interrupt never seems to trigger. I have attached the relevant files for the problem.Below is the init function for the flow sensor thread. GPIO_InitTypeDef GPIO_InitStruct = {0};  GPIO_InitStruct.Pin = FLOW_SENSOR_Pin;  GPIO_InitStruct.Mode = GPIO_MODE_IT_FALLING;  GPIO_InitStruct.Pull = GPIO_PULLUP;  GPIO_I

I am using CubeIDE 1.11.2 with a STM32F3DISCOVERY board and have created an IDE project via the integrated CubeMX GUI.I want to activate read protection via HAL_FLASHEx_OBProgram as well as the write protection for the FLASH area of my firmware (applying the same HAL function).But HAL only allows one of the two features at a time.The reason is that for every single action (write RDP and write WRP) HAL completely erases the OptionBytes via the FLASH peripheral (as you can see in the HAL source code).It is important for us to enable RDP and WRP at the same time!I could do it the bare metal way, but our project is intended for all our used STM32 MCUs and that's exactly what HAL was created for.Please, can you tell me a way to enable both RDP and WRP with the HAL functions at the same time?Thanks in advance!

Hi! I am working on a project using a STM32f407 board, I wrote the code but when I try to load it, an error shows. I saw a similar problem but the solutions didnt work for me. Here is the build output

Hi, I am looking for a replacement of VND600SP. When I searched this part, it was obsolete already. Is there any recommendation for replacement of this part? I wish there is a drop-in substitutes of VND600SP.Thanks in advance.

Hello. I'm interesting about ST202EBTR. If I use it in 3.3V, what difference is it compered in 5V.

Hi, I am trying to use a 4 I2s microphone. And I am using cubemx.I made work both of them with a sinple DMA transfer.I used I2s half duplex reciever 16of32bits sample rate 48Khz and DMA for 48*2 samples with uint16_t format. For that I used DMA1 stream 0, pheriferal to memory, half word... circular.Then I used HAL_I2S_RxCpltCallback to make things in mi code.All works well.The problem is when I include another I2S module (i2s3),I sused cubemx to obtain same configuration but in this case I used DMA1 stream 2.then  MX_GPIO_Init(); MX_DMA_Init(); MX_I2S2_Init(); MX_I2S3_Init(); HAL_I2S_Receive_DMA(&hi2s2,(uint16_t *)data_i2s2,I2S_BUFFERSIZE);   // HAL_I2S_Receive_DMA(&hi2s3,(uint16_t *)data_i2s3,I2S_BUFFERSIZE);It is possible make different dma streams in parallel. I am afraid becouse i have just to realice that stmf401re has only one DMA module. Can you help me with this?

Ideally using something like the HCI_RESET command is preferable for our application rather than simply cycling power or resetting the system. Is there some procedure for recycling the M0 processor in the stm32wb while leaving the application processor running? I'm not finding any informatio on what to do after issuing HCI_RESET to try to get the BLE radio back up.Thank you.

HiMy board has, among other things, an STM32F401RBT6 and a full-size USB B (device) connector. System clock is an external 25MHz TCXO. I have verified that the hardware is working correctly, because I have already implemented a compound device class containing USB Audio device and Communications Device class and that all works perfectly. When I try to flash a project containing a very simple MSC Device class with a 16K RAM Disk, nothing happens. Specifically I followed this ST Video tutorial: https://www.youtube.com/watch?v=GjQqZd1keBo which is very clear and he literally only writes/changes 5 lines of code. Yet when I plug in the USB cable to the PC I see nothing at all on the PC. I have tried on Linux, nothing shows up, even on an lsusb command typed in a terminal. I have tried on the only Windows machine I have, which is a WinXP Laptop. Again, nothing... The video tutorial is written for a STM32F446 on a Nucleo board; the only changes I made compared to the video were:1) Reduce the

The CubeIDE 1.12.0 release notes post mentions this:"GCC update enabled – Updates GCC 11, which is already available on the Eclipse® p2 update site"I have just updated CubeIDE to 1.12.0, but GCC stays on version 10.When I click "Check for Updates" it says "No updates found". What does it mean that the update is "enabled"? Do I need to perform a specific procedure to update it, or should it be updated automatically?

uC: STM32H725AEIxFW-Package: STM32Cube FW_H7 V1.10.0CubeMX-Version: 6.6.1IOC-File: Attached (SPI_bug.ioc)I tried to generate code with CubeMX for my project. I set up SPI2 as Full-Duplex Master without hardware NSS with the follwing pin config:SCK: PB13MISO: PC2MOSI: PC3The code generated in `void HAL_SPI_MspInit(SPI_HandleTypeDef* spiHandle)` looks like the following for MOSI and MISO:GPIO_InitStruct.Pin = SPI_MISO_Pin|SPI_MOSI_Pin; GPIO_InitStruct.Mode = GPIO_MODE_AF_PP; GPIO_InitStruct.Pull = GPIO_NOPULL; GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_MEDIUM; HAL_GPIO_Init(GPIOC, &GPIO_InitStruct);Although it should look like that:GPIO_InitStruct.Pin = SPI_MISO_Pin|SPI_MOSI_Pin; GPIO_InitStruct.Mode = GPIO_MODE_AF_PP; GPIO_InitStruct.Pull = GPIO_NOPULL; GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_MEDIUM; GPIO_InitStruct.Alternate = GPIO_AF5_SPI2; HAL_GPIO_Init(GPIOC, &GPIO_InitStruct);=> The configuration for `Alternate` is missing!With the generated code, the MOSI and MISO lines do

Hello,I am using the STM32H7B3IIT6 MCU to control a master control board, which has a push button connected to PB11 with the following hardware: My objective for this is the following:When the system is running and I press this button, the MCU puts the entire system into standby (Sends stop signals to components, puts CAN and LCD display into standby, then puts the MCU into standby to minimize power consumption by the system's battery).When the system is off and I press this same button, the MCU resets to a new "run" of the firmware and turns everything back on again.According to another forum post I made, any pin connected to an EXTI line can be used to do this, so I selected PB11. However, I'm looking through the reference manual and they just refer to "wakeup pins" and don't define what they are or how to configure them as wake-up pins. Can anyone please explain to me how to do the following steps:Configure PB11 as a wakeup pin from standby modeSend the MCU into Standby mode wh

Once again.....trying to implement an Azure RTOS NX TCP Server application on the F7 Nucleo board (since H7 processors will not be available any time soon). I ran into a hard fault at the HAL_GetTick instruction below: /*-------------------------------- PLL Configuration -----------------------*/ /* Check the parameters */ assert_param(IS_RCC_PLL(RCC_OscInitStruct->PLL.PLLState)); if ((RCC_OscInitStruct->PLL.PLLState) != RCC_PLL_NONE) { /* Check if the PLL is used as system clock or not */ if(__HAL_RCC_GET_SYSCLK_SOURCE() != RCC_CFGR_SWS_PLL) { if((RCC_OscInitStruct->PLL.PLLState) == RCC_PLL_ON) { /* Check the parameters */ assert_param(IS_RCC_PLLSOURCE(RCC_OscInitStruct->PLL.PLLSource)); assert_param(IS_RCC_PLLM_VALUE(RCC_OscInitStruct->PLL.PLLM)); assert_param(IS_RCC_PLLN_VALUE(RCC_OscInitStruct->PLL.PLLN)); assert_param(IS_RCC_PLLP_VALUE(RCC_OscInitStruct->PLL.PLLP)); assert_param(IS_RCC_PLLQ_VALUE(RCC_OscInitStruct->PLL.PLLQ));   /* Disa

I have a program running on NUCLEO-L4P5ZG board. The USB device VCOM runs fine on STM32CubeMX v6.5.0 (STM32CubeIDE v1.9.0). It was broken since STM32CubeMX v6.6.0 (IDE v1.10.0). The problem still exists in STM32CubeMX v6.7.0 (IDE v1.11.2). My workaround is to use the Core\Src\stm32l4xx_hal_timebase_tim.c file from STM32CubeMX v6.5.0. I attached the three files for helping fixing the problem. stm32l4xx_hal_timebase_tim_cz.c is from STM32CubeMX v6.5.0. stm32l4xx_hal_timebase_tim.c is from STM32CubeMX v6.7.0.

I have a strange problem booting from eMMC (Kingstone EMMC04G-M627-X03U) on STM32MP153CAA Rev.Z.By boot failure I mean fallback to serial boot (DFU over USB). Situation is as follows:Cold start never fails (Power-on Reset).Reset pin (Pad Reset from NRST) - have noticed issue maybe just once - not 100% sure.System reset generated by MPU or IWDG2 Reset - fails very often but not always. Haven't noticed any system in this behaviour.Setting both primary and secondary boot sources to eMMC greatly reduces chances of failure but does not eliminate the issue completely.Attached Boot ROM traces (without and with primary/secondary sources set) and current OTP values. Any help appreciated, thank you!

Hello team!I am newbie in STM32 world so probably i am missing something but please clarify this for me. I have found conficting informations:Datasheet "DS11532 Rev 7" at p. 47 says "Battery Charging Specification Revision 1.2 support"Reference Manual "RM0410 Rev 4", p. 1579 - "supports charging port detection as described in Battery Charging Specification Revision 1.2 on the FS PHY transceiver only." the same manual at p. 1638 describes registers related to BCD functionalityhowever:the same manual again says at p. 1581 that this MCU doesn't support BCD at allthere are no BCD related functions in stm32f7xx_hal_pcd_ex filesthere are no BCD related registers in stm32f767xx.h fileso i am little bit confused about that.BR.Lukasz

I am attempting to use TraceX in my NetXDuo application. But when I enable TraceX in the Software Packs of CubeIDE (TX_ENABLE_EVENT_TRACE) I get compiler errors in all of the calls to save a tracex event. The macros that defines the calls to tracex services appear in nx_api.h, but are not defined, and hence the _nx_trace_event_ service is never defined.  I saw a discussion of this same issue over in the Renesis community where a workaound fixed the compiler issue. https://community.renesas.com/mcu-mpu/embedded-system-platform/f/forum/10314/undefined-reference-to-nx_trace_in_line_insert-when-arp-probeBut t his workaround did not fix the STM code.Can anyone suggest something that may help?Thanks,MikeH

I am rather new to STM32. Ιn my project, I am using an STM32L072KZU6 and I want to debug the firmware using the ST-LINK/V2-ISOL. I connected both SWDIO and SWDCLK pins to pins 7 and 9 of the ST-LINK/V2-ISOL, along with +3.3 V on pin 1 and ground on pin 4. (Pin 2 is connected to +3.3 V, too.) In ST32CubeProgrammer, I can connect to the target MCU without problems:However, when I try to use Keil uVision v5.37.0.0 and click on Start/Stop Debugging Session, I get a dialog box with the message "Trace HW not present":and, when clicking on OK button, another dialog box appears with the message "Error: Target DLL has been cancelled. Debugger aborted!":Any clues, anyone?Here are the settings for ST-LINK debugger in Keil:

In the peripheral's User Constants tab, unhighlighted IP Handle Label values are in light gray, which makes them illegible. On my monitor at least.

I did not tested if this is specific to all MCU but for U5 familly this is sure:How to reproduce : Launch cubeMX, (6.7.0)select U5 board like nucleoGo to project manager, and select under Toolchain - Makefile.--> Bug, the Makefile genereted is missing some details on CPU, so cannot build.To solve it add : CPU = -mcpu=cortex-m33after ####################################### # CFLAGS ####################################### # cpuMoreover, and i am not sure about this but I think I read somewhere that U5 was using : fpv5-sp-d16 and not fpv4-sp-d16 as in generated makefileso I replaced FPU = -mfpu=fpv4-sp-d16by this : FPU = -mfpu=fpv5-sp-d16Please review the makefile generation under cudeMX seems to have some mistake for U5 series at least.Hope this help and avoid other to lose time to spot this.
