My H7 board has a strange issue: if I connect it to USB, Windows recognizes it (PRODUCT ID & VENDOR ID are correctly shown) but no communication (by CDC_Transmit_FS()) happens: CDC_Transmit_FS reports me BUSY_USB.If I reset (by the pushbutton) my boa...
Hi,I experience strange behaviour with the just reworked H7 ethernet driver in STM32H725 with LwIP + FreeRTOS environment. A continuous transmission of UDP frames (bursts of 3..4 frames every ~ 50 ms) comes to halt after just a few successful loops. ...
HI,I am using a stm32f401RE chip on my board, a single virtual com port is working fine, but if it is possible to run twice virtual COMS? and what are the processing steps?Regards,Naren
I'm working with the Nucleo-64 development board with an STM32L476 microcontroller and I'm using the USB source code that STM32CubeMX has generated for me. In my project the peripheral interrupts have the same priority as OTG_FS_IRQHandler and hence,...
I have a custom board based around the STM32L496 that creates a USB HID device. I have two projects (built in IAR Embedded Workbench), both of which have this board and micro as their target. On the exact same board, one will enumerate USB at FS, one...
I'm working with the board B-4SI-IOTI and I'm trying to program the board with the Provisioning.bin file from package X-CUBE-AWS. The first time it works but now appears this message on the terminal:---------------------------------------------------...
Hi,I am trying to test the HSI48 clock for the USB (with the CRS SYNC USB). But I don't find any simple example for the NUCLEO-U575I-Q... Now that the USB-DEVICE is not supported in CubeMX for the U5 (only on github) I am really struggling with the U...
Which driver is faster from HAL or LL so cpu can perform other important tasks.For example to read & write gpioUsing HAL driver,Using LL driver,Using direct access MCU resistor.
