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'm using LL driver in projects and I found these differences comparing the newest LL driver version (1.7.13) with my current why:in file stm32f4xx_ll_usart.h/c (macro with prefix ATOMIC_ is now used in several functions)LL_USART_EnableDirecti...
I need to upload large data files (around 200MB) from my STM32L485 board to AWS S3 storage. I was planning to use direct S3 upload via an HTTP request. However, my data cannot be loaded in RAM so I was thinking of sending it in chunks. But, I have se...
I would like to test USB on an STM32L476 Nucleo-64 development board. I use STM32CubeMX version 6.2.1 and the library it's using is "STM32CubeL4 Firmware Package V1.17.0 / 11-February-2021". I select Nucleo-64 in Board Selector in STM32CubeMX and the...
Hi,For USB HS device mode DMA to work correctly, we need to consider:1- address alignment (4byte align due to hardware design) ... OTG_D(I/O)DMAx registers2- size of data (not recommended but can be set in byte size using HBSTLEN in OTG_GAHBCFG regis...
I read AN2606 but i couldn't understand exactly. My understood is that if i connect boot0 pin to ground, main flash memory is gonna be selected. My question is if i do it(connecting boot0 pin to ground), will i lose the ability which enable me to pro...
I'm doing an Open bootloader project for STM32L4R5ZI MCU, I don't want to use lower layer configurations for Usart, so how should I adapt the open bootloader project for my controller, what are the changes i need to do?
I am using an stm32f401rc microcontroller, peripheral USB mass storage host is not detected, I am generating code as per the USB MSC HOST labs document.MX_USB_HOST_Process(); switch(Appli_state) { case APPLICATION_IDLE: break; case APPLICATION_START:...
Hi,I have massive trouble while implementing USB HID on a STM32F373.I use the CubeIDE, made a new project configured the USB pins and the USB Device middleware as „Custom Human Interface Device Class„.The report descriptor has a length of 37 Byte and...
