I need create composite device for the Virtual com and USART1 also USART2.That meaning when we connect the stm32 to PC show 3 COM ports,it's Possible to do that with STM32F042x6?i need help to create the composite device? or see a good example to do ...
I have done this: 1) created a file using fatfs on flash open and read ,it is working. 2) created a usb interface configured as msc device,when plugged into pc, new drive gets created, however it asks to format it. I have added only read functionali...

Hello,I am working on a project where I am interfacing SD card with SPI using USB MSC with STM32F103 processor. I could achieve reading speed of 580 MB/s. I am using HAL library. For the sake of improving the program, I want the USB to work with dou...
Hello, I am using STM32F746 MCU and trying to use SDCard in DMA mode using FatFS.This MCU has Cache also so for any conflict between DMA and the cache, I have disabled the cache. I am just trying to create files in an infinitive loop at startup. (Cre...

I have a project to connect STM32F407 Discovery board to PC via ethernet. I have tried to use LwIP and LAN8720 for my external PHY with RMII. But i still cant managed to connect or ping directly to my pc. I have configured the IP to use DHCP or stati...
Hello,I am new to STM32 and also to c/c++ programming. I communicate witm my STM32 via VCP and I can transmit and receive bits. But I would like to use the received bits to create a function (switching LED on, etc). Now I have looked on the internet ...
I am trying to migrate a project from a NUCLEO-F746ZG to the NUCLEO-H746ZI2. In this project, I sample 6 different ADC channels using DMA. When configuring the DMA in CubeMX I cannot find the "DMA Continuous request option". I tried setting the DMA t...
I am using STM32L476VG MCU.I had set up TIM1 to generate an interrupt callback via callback function HAL_TIM_PeriodElapsedCallback.And this work successfully.After this CallBack function finished executing the codes, at the end of the code, I would ...
