Hello,everyone,I have a problem when I want to use STM32Cube_FW_F4 Demo Project to develop a USB MSC Project with Freertos. The main problem is it seems that the HAL_HCD_IRQHandler() just can not occur,but when I did not use Freertos, which worked j...
I have only managed to find examples using HAL libraries which I am not fond of. I Have been looking through the LL header files genereated by STM32cubeMX for any flash programing information at all but I was unable to find any. If there is not supp...
The USB-HID ST library comes with an example of Mouse device that I have adapted successfully.However it only has a single Input endpoint to send reports to the Host.I am mainly interested in OUT endpoint for communication Host to device.Does anyone ...
Hello. I am using STM32F4279ZI MCU with FreeRTOS. I want to compare efficiency of bare-metal and OS based program implementation. While doing some tests I have noticed that the same function called from bare-metal aplication is much slower than that ...
I have an application program running on a Nucleo-H743. While most of other components are working, I'm having trouble with onboard USB to work.The USB handling is ported from CDC_Standalone application example for EVAL from STM32Cube_FW_H7_v1.3.0....
Hello masters,I am trying USB_OTG_FS application with STM32f401VE MCU on own designed board.Program going infinite loop at startup _stm32f401xe.s file . I traced to where the problem occurs. It seems; /* Deactivate the power down*/ USBx->GCCFG...
Hi,I am working on BlueNRG-2 and I need a funcion "hal_i2c_isdeviceready()" to confirm NFC eeprom IIC ready. In ST BlueNRG-2 demo, it used LL library of IIC.Could you give me some demo like "hal_i2c_isdeviceready()" in LL library.Thanks a lot.

I want to signal a possible bug in CubeMx version 4.27, in the STM32L4xx HAL library package. In the ADC configuration of the external trigger, the TIM4 TRGO setting does not work.I think the error is in line 518 of file "stm32l4xx_hal_adc.h". The or...
I am programming a USB-HID device based on STM32 CubeMX Mouse example.I made some modifications (interface, endpoints, report descriptor) and I am currently testing enumeration.Everything seems to be OK except that the lsusb command fails to dump the...
