Posted on September 25, 2014 at 08:45Hello! I'm using the USB CDC class implementation provided by STM32CubeMX 4.3.0 (firmware library v1.3.0). Is it possible to check on the microcontroller if the virtual COM port has been opened? I want to transmi...
Posted on January 26, 2018 at 16:55Hi there,we are currently developing the firmware for our custom board with an STM32F746 MCU in LQFP-100 package. Our current version is working well and now we want to be able to download updates via USB DFU. I re...
Hello! We use a chip in our product and connect it via USB, so we need VID:PID. STM can give VID as a free service. I opened a case in the tracker, but there is no answer for 3 weeks. Who can I contact on this issue?1. COMPANY NAME AUTHORZING USE TO:...
I'm trying to make work USB_HS peripheral (External PHY is USB3320). I configured CUBE project, generate code, pass 24 Mhz to USB3320 and there is nothing. Even pull up resistor that should indicate new USB device isn't working.MCU: STM32H743IIT6 mxC...
I'm tring to set up an HID on a NUCLEO-STM32H743ZI. My demo code is very simple:uint8_t buffer[8] = { 1, 0, 0, 0x04, 0, 0, 0, 0 }; while (1) { /* USER CODE END WHILE */ /* USER CODE BEGIN 3 */ if (HAL_GPIO_ReadPin(GPIOC, GPIO_PIN_13) == GPIO_PIN...
Hi All, We are using STM32F746 MCU with external Memory. We use internal flash for bootloader image and our main image is on QSPI memory. We read something about STM32F7 HW issues for example to access QSPI using DMA, Cache's need to be disabled. On ...
I've got a problem with stm32f407zet . I use also LL drivers and 3 ADCs with dma .No problem when run separately , e.g. only ADC 1 - results are corrects , only ADC3 - results are corrects .Problem is when I turn on two ADC by ://adc1 LL_ADC_C...

Hello! I try to make SDIO 4 wide bus and USB Host MSC class works together. I want to write data to microSD card and copy that files to USB stick. It works separately. When i configure SDIO but not configure USB in CubeMX, data writes to SD-card. Whe...
Posted on June 07, 2018 at 17:51I'm using an STM32F723 with a customised USB driver to capture Isochronous data.I can capture the data in 4KiB chunks. The data is DMA'd into internal SRAM then modified and copied to internal SRAM then DMA'd to an SD...
