Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
BackgroundWe have a battery-powered device using:MCU: STM32 (STM32L4series)Modem: Quectel BG95 (cellular)Communication: UART with Idle Line Interrupt (HAL_UARTEx_ReceiveToIdle_IT)Power mode: Device goes to sleep periodically, wakes up to communicate ...
Hi ST community,I am facing an issue of 10us delay between CS line going low and SPI SCK start, when I am doing SPI communication with a slave device, which supports upto 15MHz SPI communication.Below is the main.c file snippet for your reference. Pl...
Hello,I am using the Nucleo U575ZI-Q board. I need to use GPDMA synchronized with a timer to set multiple GPIO pins synchronously, perform SPI transmission, and configure PWM periods.I have found a working combination: software request + trigger TRGO...
大家好！问题是这样的： 我正在尝试使用 STM32 ISP-IQTune 应用程序通过 STM32N657X0H3Q 板读取 PC 上的 IMX335 相机数据。但是，IQTune 无法检测到任何可用的 COM 端口。这是我的设置：硬件：板：STM32N657X0H3Q相机：IMX335（MB1854B模块，根据文档提供原生支持）。固件：已从 STM32N6 固件包中刷新 DCMIPP_ContinuousMode 示例。连接：已将板上的两个 USB 端口连接到 PC（USB-C 电缆）。开发板...
Good evening, I need freeRTOS tick speed to be greater than 1kHz, I tried to change the configTICK_RATE_HZ parameter but get a divby0 error which I can't fix. Is there a way garanteed way to achieve what im looking for? Thx in advance
Hello! This is the first time I'm using an STM32L0 (...11F4Ux) and also the first time I've tried implementing an I2C IRQ Handler. The code snippet mostly works, but there's a bug in which a READ commands sends data from the previously requested regi...
Hey everyone,I'm currently trying to integrate the STM32 FP-AUD-AEC-1 software package in a multithreaded environment (ThreadX) on an STM32wb55rev7 mcu chip. Library compiles and runs but eventually hard faults during thread initializations. Any advi...
Hi community,Before I start discussing my specific issue, I would like to know if dual USB host operation is allowed on STM32H7 MCUs. The H7 MCU has both FS and HS USB cores, and I want to configure both FS and HS as USB hosts, not using the OTG feat...
Hi everyone, my custom board previously had an STM32F746BGT6. Since we were looking for a microcontroller with a graphics accelerator, we opted for the STM32H743BIT6 (which is pin-to-pin compatible). All the peripherals work, but I'm having trouble i...
There have been previous posts about determining how the DFU serial number is formed from the 96-bit Unique ID. However, when using the ROM bootloader for the STM32F723xx MCU I don't see unique serial numbers at all. I am always seeing the same DFU...
