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...
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 + ...
I'm already achieved a USBX-MSC class, and also a FileX in MCU local.I know that using two file systems at the same time is not recommended, but still have some questions. 1. I implement the ux_deveice_msc.c as followed. Use PC-Windows to create a fi...
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...
Hi everyone,I’m working on an STM32U3 project and ran into an issue where flash erase was failing with error code 0x00000080 on page erase, even though the option bytes and addresses appeared correct.After debugging, I found that explicitly setting t...
Howdy;I have a li'l stm32u031, with a pushbutton attached to PA0. This MCU is clocked with no external oscillators. I've configured the button/pin to work with Timer2/Channel1 in Input Capture mode when the MCU is in run mode, to detect and measure b...
As the title says.I am using STM32H523RCT6 with no RTOS (no ThreadX) and USBX in Standalone mode.The code is basically:MX_USB_PCD_Init();MX_USBX_Device_Init();HAL_PCD_Start(&hpcd_USB_DRD_FS); Which executes, but as soon as the USB_DRD_FS_IRQHandler i...
