STM32 MCUs

Hello Friends,I am looking for MCU. Kindly suggest. Below are the minimum requirementsNeed two SPI.  Need to read data of two sensors via SPI simultaneosly & continously. Need one UART  Need smallest possible foot print.  WLCSP12/TSSOP20/UFQFPN20 Do not want to use external cyrstal for clock. Want to use internal clock Robust for shock, vibration.  Pricing is no issue.Kindly suggest..   

Split from this post.I’ve just tried testing the out FIFO depth.The STM32F427 is operating at 179.8MHz.The DMA2D is configured for memory-to-memory transfers (so only the out FIFO is used - this is how I intend to configure the peripheral to drive the DAC).The DMA2D dead time is configured for the maximum value (255), which allows one AHB transfer to the DMA2D every 1.4 microseconds.The timer generating the NWAIT signal is held low for several hundred microseconds after the DMA2D is enabled and then generates NWAIT pulses that allow the FMC to write a value every 8 HCLK cycles (every 44.45ns).This is the resulting output on the FMC NWE signal, with the controlling NWAIT signal (from the timer) also shown: This suggests the FIFO depth is 48 (16-bit) words.But what happens next raises another question.  This screenshot shows the first burst of 48 writes to the FMC, followed by the next 3 bursts:The subsequent bursts are only 16 writes long, and the time between them (the first interval i

I am building a live camera feed project using an STM32H747I-DISCO (MB1166-A09) board and a B-CAMS-OMV (MB1683-CAMS-A02) camera module.I tried using the standard example capture mode ,i set up everything but i always get stuck here ,any solutions?

Currently, I am using the STM32F412RGT6 64-pin package to drive an 8-bit MCU interface screen. However, I am unsure if this MCU supports FSMC.

What are the sizes and configurations of the FIFOs (foreground, background, and out) on the STM32F427 DMA2D (Chrom-Art)?

  When I was developing the stm32u575, I needed to set the threshold for the bor (power-on reset). I wanted the device to reset when the voltage was below a certain level. While configuring the bor threshold for the stm32u575, I followed the configuration process of the stm32f405, but it didn't work. The program got stuck at HAL_FLASH_OB_Unlock(). Why did this happen? What was the problem? FLASH_OBProgramInitTypeDef OBInit; HAL_FLASHEx_OBGetConfig(&OBInit); OBInit.USERType = OB_USER_BOR_LEV; OBInit.USERConfig = OB_BOR_LEVEL_1; HAL_FLASH_OB_Unlock(); HAL_FLASHEx_OBProgram(&OBInit); HAL_FLASH_OB_Launch(); HAL_FLASH_OB_Lock(); 

In this documentation, I can find a detailed description of the torque/flux (current) PI controller implementation, but there is no clear explanation of the speed PI controller design or tuning. Could you please explain how the speed PI (KP, KI) is derived, and what criterion ST MC Workbench uses to compute these parameters automatically?

Dear  Team,I am currently working on an application based on the STM32H563ZITx microcontroller using the NUCLEO-H563ZI development board.The application is designed as a gateway that communicates with another controller through a UART interface. The same UART interface is also used to program the target controller with firmware updates.For the software implementation, I am using STM32CubeH5 v1.6.0 and have adopted the Nx_Iperf reference project for the NUCLEO-H563ZI board to develop a web-based user interface.The following functionalities have been successfully implemented and tested:Reading data from the target controller via UART Writing data to the target controller via UART Firmware download and programming through the same UART interfaceHowever, I am encountering an issue when transferring firmware (.bin) files. The system appears to accept only about 54 KB of data, after which the transmission stops. As a result, I am unable to transfer larger firmware images.My application requi

Hello,Because there is no active handle in DMA list for DCMI DMA initialization (bug!?) I searching for the ways to enable and use DMA, I can't find examples for parallel mode except for CSI serial, if I switch to use DCMIPP in parallel mode then the cubeMX do not generate msp initialization code function HAL_DCMIPP_MspInit for DCMIPP interface (no pinout, RCC, IRQ...), and in DMA list DCMI_PSSI handle stays inactive,all my attempts to setup DCMI DMA do not work and DMA throws error 0x40, DCMI and camera working well, I getting hsync and vsync callbacks firing and counters show correct values, I tryed various settings but still cant start DMA transfer, there is my test and msp initialization code, please check: uint32 err0 = HAL_DCMI_Start_DMA(&hdcmi, DCMI_MODE_CONTINUOUS, (uint32)frame_buff_DCMI, 320 * 240 / 2); uint32 err1 = HAL_DCMI_GetError(&hdcmi); HAL_Delay(5000); uint32 err = HAL_DCMI_GetError(&hdcmi); printf("DCMI %u %u, %u %u %u, %u %u\n", hdcmi.St

Hello everyone,I am currently working on an STM32-based project and have encountered an issue with UART communication. The UART works correctly after startup, and data is transmitted and received as expected. However, after running for several minutes, the communication suddenly stops and no further data is received.I have checked the wiring, baud rate configuration, and power supply stability. I also monitored the application for hard faults but could not identify the root cause. The issue occurs consistently after prolonged operation.Development Environment:MCU: STM32 Series IDE: STM32CubeIDE Communication: UARTHas anyone experienced a similar issue or can suggest possible causes and troubleshooting steps? Any guidance would be greatly appreciated.Thank you.

Hello,I am ready to use STM32C531 in project. Right now, I am using Keil MDK V5.29 and it does not support this micro. Can anybody help to tell me which Keil version support this micro? If I do not use Keil, does any other IDE/Compiler support this micro develop?  Thanks,  

Hi all! Thank you for taking time to assist me. I am attempting to make a composite USB Device on the NUCLEO-C562RE. I found the Middleware USBX examples and the core drivers exist in my toolchain at: STM32CubeC5/middleware/usbx However, I cannot seem to find the middleware configuration for USBX in STM32CubeMX2. My pack manager in the STM32CubeMX2 is set to this default value: "cube.packManager.cmsisPackRepositories": ["https://developer.st.com/st-pack-server/api/v1/pidx/STMicroelectronics.pidx"] Please let me know if I have missed anything or if you need further information from me to figure out the root issue. The examples, linked above, clearly auto generated the USBX files using the MX2 software, but I could not find the documentation that allowed me to generate those files. I would greatly appreciate it if someone could assist me with this.   EDIT: I saw this forum that says support isn't out until Q3. Does that mean I have to write the generated cod

Hello!I am working on a project using the STM32U375CGUx MCU, and I am trying to implement a Stereo Audio Acquisition system using two omnidirectional digital PDM MEMS microphones.Hardware Setup: Microphone L: L/R pin tied to GND (Rising Edge data output). Microphone R: L/R pin tied to VDD (Falling Edge data output). Both microphones share the same lines connected to the MCU: PB4 (ADF1_SDI0) for the clock and PB3 (ADF1_CCK0) for the data stream. The Issue:When configuring the peripheral through STM32CubeMX, I am unable to set up a true Stereo configuration. I can only make it work in Mono.Looking at the generated HAL initialization code, I am forced to choose either MDF_BITSTREAM0_FALLING or MDF_BITSTREAM0_RISING for the FilterBistream parameter. There is no option/macro to sample both edges (interleaved) simultaneously on the same filter instance:AdfHandle0.Instance = ADF1_Filter0;AdfHandle0.Init.CommonParam.ProcClockDivider = 6;AdfHandle0.Init.CommonParam.OutputClock.Activation =

Hi ST!I’ve been having some difficulty trying to integrate my UART project inside the architecture outlined in your OEMiRoT_Appli_TrustZone example for the NUCLEO-U385RG-Q. Note this example is incompatible with CubeMX and therefore I’m somewhat on my own when it comes to setting up additional peripherals (like USART3).I’m currently able to send in a string to uart3 using HAL_UART_Transmit, however am not able to trigger an interrupt when attempting to input to uart3 - code below: char *msg = "USART3 TEST 3\r\n"; HAL_UART_Transmit(HUART, (uint8_t*)msg, strlen(msg), HAL_MAX_DELAY); HAL_UART_Receive_IT(HUART, &uart_rx_byte, 1);I’ve tried using VSCodes compare functionality to mirror a CubeMX generated TrustZone example with uart enabled, so far adjusting sections of stm32u3xx_it.h/c, stm32u3xx_hal_conf.h/c and partition_stm32u385xx.h, with some nudging from this forum question https://community.st.com/stm32-mcus-embedded-software-32/stm32h563-trustzone-usart3-interrupts-not-working

Hello, I'm using an STM32U5G7VJTx MCU with a 480x320 display, connected to the FMC in 16-bit mode, and everything works fine using the GPU2D. I'm not using an existing GUI framework.The pixel format used by the display is RGB565 (16bpp), so for gradients, I want to use dithering to soften the banding. I found this definition in the 'nema_graphics.h' file:#define NEMA_DITHER 0x80U /**< Nema Dithering */However, it seems undocumented. How do I make use of it?Kind regerds, Jack.
