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...
I’m working on STM32F405RGT6, receiving audio from ICS43432 (MSB First, 24bit on 32 bit frame).sing Circular DMA (double buffering) to read it in. After 3 days of debugging and millions of mem corruptions and stackoverflows later I finally managed to...
SDMMC HAL driver implementation is full of timeouts like this:uint32_t count = SDMMC_CMDTIMEOUT * (SystemCoreClock / 8U / 1000U); do { if (count-- == 0U) { return SDMMC_ERROR_TIMEOUT; } sta_reg = SDMMCx->STA; } while (SOME_FLAG_NOT_SET);I...

Hello,I want to generate an arbitrary waveform by a timer using DMA. The waveform is using different pulse widths and also varying periods in multiples of 25µs.By reading AN4776 and HAL documentation I figured out it should be possible with HAL_TIM_D...
The FSBL → Application jump is working fine, and the application is running properly from external flash.However, I am facing the following issues:Ethernet IssueEthernet initialization is successfulPHY link is UP, but speed is 10 Mbps (Full Duplex)Pi...
Dear STM32 Community, I am currently working with the STM32WB55CGU6 and aim to determine the maximum practical data-transfer rate when utilizing USB device mode with the CDC (Virtual COM Port) class.I am particularly interested in the real-world USB ...
Greetings,I am working on testing a STM32H573 based HW design, which uses an external 4-port USB-2.0 Hub.I plan on using USB Flash drives, and read/write files to them as a diagnostic test.I will instantiate the STM32H573 USB interface as Host-mode, ...
Hello,On a STM32H7RS are using the USB_OTG_HS peripheral in PCD_SPEED_FULL mode using internal clock.After I was able to configure the clock so that the MCU is responding on enumeration requests. The responses however seem to be partially incorrect; ...
Hello, i am using F446 and i am contemplating using FreeRTOS CMSIS V2 software timer to generate PWM to control motors via motor drivers (IC chipset). Is this possible? Or must I use the hardware timer, TIM1~7 ?
Hello, I am following this guide:How to integrate TouchGFX and camera middleware on an STM32N6570-DK and seem to be getting an I2C1 undefined reference (below). Is there something I need to change? I have I2C2 enabled in my .ioc, but don't see anyt...
