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...
Hi,Is there a way to browse available STMCUBEMX projects for various product lines, without downloading the packages in their entirety?I just want to see what projects there are.Just seeing the projects name and briefs are enough.Thanks!
I have erased, have written (with HAL) but a can't read with HAL.
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
I'm still very new to STM32 processors, and using CubeMX to generate my basic code structure (for TrueStudio). In the code below, if I uncomment code section A, the yellow LED blinks, but not evenly... At low values such HAL_Delay(100), the high time...
I'm still trying to get FatFs to work with 4 wires. My PCB has been properly traced, each line is within a few mm of all others, and has a 33K pull-up. Internal pull-ups are off.This setup works fine at full-speed (45 MHz) when using only 1 wire, b...
