Hi!I don't know really how to explain this. But I have enabled CANBUS and it works very good. I also have activated USB and it works too.But since I have changed the preemption from 0 to 1 for CANBUS RX0, I have no ability to use USB connection.I cha...
I have been using USB_FS for some time now and recently added the EXT13 IRQ for the user button in the STM32L5 DK. I set a task to toggle a pin when the button is pressed and noticed that if the USB is running, the event does not wake the user button...
I used ThreadX and USBX in the project. When I only use USB as a HID Device, STM32 can transmit data to the PC 1000 times per second, but when I use USB as a CDC+HID composite device, the transmission frequency of HID is greatly reduced. Will increas...
I successfully used USB DFU on STM32H7, and I want to perform the same operation on STM32F105. I learned from the manual that the system BootLoader address is 0x1FFFB000. But when I try to jump into USB DFU mode, windows prompts the device descriptor...
We have a custom board with an STM32F407 on it. I used CubeMX to create the project and enabled HTTPD. I used the example LwIP_HTTP_Server_Netconn to get a webserver running. I have a few pages working including a dynamic page. Next step was to c...
Hi,I am trying to send and receive the float variable between STM32H745 and my PC. I can only transmit and receive strings. Is it even possible to handle any type of data rather than string. Thank you.

Hi, trying to order the free NUCLEO-H723ZG board with the code that was provided.After applying the code for the first time the order page asks to login with my username.I did that to complete the order, but then it's impossible to apply the code, as...
Posted on May 31, 2017 at 23:17 I am trying to make usb operate in STM32F103 but it seems doing so is a lot different than usb fs in STM32F4 series. In F4 series it was just enough to connect usb connector to Data pins and MCU would take care of ...
