I'm using AL94 library on STM32H7 for USB Composite functionality. The MSC class driver appears practically identical to 'native' MSC Class provided by STM.However, I am having difficulties running even the simple RAM disk example - the drive is corr...
Hello everyone and thank you for your help, I am being using the STM32F746G-Discovery Board for a couple of months first time working on it and I am currently working on a project where I want to transfer firmware to board which have a SD card on it,...
Hi,I would like to know if I can emulate the STM32H5 (which is ARM cortex-M33) via Qemu. And if so, are there any limitations in emulating different drivers, especially the ADC and PWM within FreeRTOS Kind RegardsHani Akeila
Hello, I was trying to use RTC battery backup on a nucleo F446RET6.The problem was that the battery (CR2032) connected to VBAT tries (and can't) to power all the board.Looking to schematic diagram, I see that VBAT pin is connected to VDD thru SB45.Re...
Hi, I'm using a STM32H7S78-DK board along with stm32cudeide 1.16.0. I'm loading the example LTDC_ColorKeyring which work fine, here is the issue... I'm trying to implement uart4 connected to the onboard ST-link. If I init MX_UART4_Init() and use HAL_...
there is nothing on github. there is initialization by SPI before the LTDC works is there a sequence like you initialize it first over SPI then MX_LTDC_Init() or it does not matter I do have the initialization code but I am missing something void ...
Hello,I'm new about STM32 world. I'have a problem to receive CAN Message with a F767ZI.I tryed te code bellow, it's run and send the message wit ID 0x0CFFA22D correctly but don,t receive any message.I don't have idea where is the problem.Could someon...
I'm currently working with the STM32U5G9J-DK2 board, and as a newcomer to this board, I’m finding the USB CDC-ACM setup challenging. I’m using CubeMX 6.6.1 to generate the initial code, intending to send data over USB. However, I'm facing a few issue...
I am working with a Quadrature Encoder that uses TIM2 (encoder mode). The encoder mode automatically captures an increase in the register htim2.Instance->CNTI am trying to use DMA to fill a buffer with the CNT values however it does not seem to work....
Hi guys,I've a problem and I hope you can help me.my project must acquire a ps2 keyobard and a ps2 mouse and must be see with the usb.This is ioc configuration: The first step I tested the firmware only acquire a keyboard and works fine. The PC see ...
