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 adapted the official BSP example code (available at https://www.st.com/en/embedded-software/stm32cubeu5.html, stm32cubeu5-v1-8-0.zip) to acquire and process audio. My code is running very slowly on the board. We thought the slowdown might be due to...
First and foremost, they aren't perfect. The code has tons of work left. But it took me SO long to get ANY i2s audio data from my guitar to my computer, the major hurdle being mostly the lack of USB Microphone drivers provided by the stack.Now that I...
Hi, My board consists of stm32h733 that interfaces SDRAM via FMC. I want to execute code from SDRAM. Code is loaded from external flash(OCTOSPI) to SDRAM at address 0xc0700000.But running the code from this region causes hard-fault disabling the Debu...
Hello, I am developing a custom made PCB, for a pico balloon, mounting a STM32F103C8T6. For this project I will need to use low power techniques but before going deep into the Sleep/Standby/Stop mode I was working on understanding and reducing the po...
Hello, I have made my own STM32F732RET6 board that has a USB FS configured as a Stereo, 24 bit 48kHz Audio Interface and SAI2 connected to an SN75176BDR (Differential Bus Transceiver IC) because I want to transmit AES3-AES/EBU (same as SPDIF) audio d...
Hi, I'm trying to get a few lines of text displayed on an OLED screen using 4-wire SPI on an STM32H755 board, but I haven't succeeded yet. I've looked into the sample code provided by the manufacturer (which is Arduino-based), but it hasn’t helped mu...
So I want to use a capture compare to measure an input frequency 0.1Hz to 100kHz. Peripheral clock is set to 32MHz to cover full range and maximise speed of calculations. At lower frequency I have to count the number of times the over capture call-ba...
Hello,Sorry if it's a *** question but I don't understand something.I want to have an HID and MassStorage usb device. I've seen that ST add USE_USBD_COMPOSITE but I don't understand why we use it for USBD_ClassTypeDef.For me, we have 1 device desc + ...
Hello,I am experiencing an issue with LwIP on the NUCLEO-F746ZH board. I am using STM32CubeIDE 1.14.0 with the STM32F7 firmware package v1.17.3 (I also tried v1.17.0 and the latest CubeIDE version, but the errors still persist).In the screenshots I s...
This is a line of code i don't understand, /* Force the TIMx prescaler with immediate access (gen update event) */ LL_TIM_SetPrescaler(TIMx, pHandle->HALLMaxRatio); LL_TIM_GenerateEvent_UPDATE(TIMx);The code is part of the __weak void HA...
