If a charger is plugged into the USB (rather than a computer) then USBD_MSC_Init() is not called. Consequently pClassData is left NULL. If the USB is then stopped via USBD_Stop(), then the USBD_MSC_DeInit() is called and the NULL pointer is accessed ...
Hi,We are using STMCubeMX to generate the code for USB-Device Mass Storage class for STM32L4R5 controller.We have to check the usb connect/disconnect status run time.Try to use HAL_PCD_ConnectCallback/HAL_PCD_DisconnectCallback function but never get...
Hi,I'm waiting for 1.4.0 due to lack of LL drivers in 1.3.0.According to the thread linked below, 1.4.0 was planned "beginning of 18Q4", is there a new roadmap or release date when we can expect it?Currently it's holding us back from using the H7 at ...
My app run on the STM32F103 platform. An multiple channels audio stream,with about 768 bytes / ms, need to be send to the USB host. How can i do it with the only 512 byte package memory on chip ?
We have been working on developing a USB dongle based on STM32F413/L476 which acts as a CDC-ACM serial device. We mostly have everything up and running expect for an issue with USB which shows up sporadically and details are as below:USB CDC-ACM inte...

I have erased, have written (with HAL) but a can't read with HAL.
I'm trying to wrap my head around HAL_GPIO_EXTI_IRQHandler...Why is only the "Pin" used in the parameter, and not the "Port". Really, why not both?According to en.DM00031020.pdf page 382 section 12.2.5 "External interrupt/event line mapping", it appe...
Hello,I'm trying to port a library written for STM32F413 to another device of the family, the STM32F407. The library depends heavily on the Flash HAL module driver, which I have never used before in any of my projects. The driver for the STM32F4...
Hi guys, does anyone draw a circuit to get the stm32F4 MCU with USB connector working properly . Thanks
