Hello!I'm migrating from STM32F7 to H7 MCU, but I incurred a strange problem (well, two strange problems...).I have a QT program that opens COM ports by:void Sensor_interface::open_port() { if (Device_Sensor_Port.isEmpty()) { qDebug()<<"N...
I am using STM32F407VG board for logging the data continuously using FATFS. When I am writing the data it is working fine some time , then suddenly it is giving f_write or f_sync error . After that error It is not able to write and it is stopped ...
Hello Dear Engineers and DevelopersSo far I had been able to use SD-CARD and USB in CDC mode using STM32f429, but when I add Freertos. USB fails to enumerate on PC. Also, I have been able to use FREERTOS SDCARD and Touchgfx simultanously.Here is my p...
Hi, this subject has already been treated with other boards in other forums, but libraries and tools have changed since then so i thougth i could open a new question. So i use CAN1 bus in the Discovery STM32F407 in order to share data between 2 disco...

I am using the x-nucleo-idw04a1wifi extension shield, and wanted to test it with a firmware project (HTTP_Request). The blue led and the right bottom led used to blink, but now, It does not anymore :( After entering my router information, I get this ...
Hello everyone,We use a STM32F7 and we have built a bootloader which uses the USB-DFU library from ST (usbd_dfu_flash). We can successfully program the internal and external flash. We noticed that it takes quite long so we were looking for ways to in...
Specifically for STM32F103C8T6 and STM32F103RCT6.
Hello,Is it possible if MCU communicates with PC in virtual COM port, using USB connected as shown below.USB_DP --- OTG_FS_DPUSB_DM --- OTG_FS_DMCould anybody please show me example?Thank you.
Hi,I'm looking for an example schematic of a USB PD charger interface using STM32G071G8U. Current questions are:Is the available singe CC pad (PA8) all you need from the hardware point of view? Is there any option to connect D+ and D- to allow 5V loa...
