Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
I would like, if possible to use the 64 pin package in my design. The problem is that I need a CAN bus and would like to program the chip straight from USB (with potentially needed level shifting?) with the DFU I've heard so much about. I can move CA...
I am trying to configure the STM32L476 as a USB Microphone, my input is an analogue microphone through the ADC. I configure the device as an Audio class, at first my computer found it as a speaker, so I search about it and find that I need to redefin...

I am using multiple devices which access I2C communication channel. Can anyone suggest me what should be the preferred method to avoid clashes between the devices.The devices are placed across different RTOS tasks.
Posted on November 10, 2014 at 14:30Hello. I am using the new HAL library for writing a program for STM32F4Discovery (for university presentation). The program activates a USB FS CDC device once running to speak with a PC. I've attached an SD card s...
Hi, I'm trying to use FreeRTOS Tickless idle mode. When I am debugging my code (using breakpoints), I see that the code enters vPortSuppressTicksAndSleep function. /* Sleep until something happens. configPRE_SLEEP_PROCESSING() can set its parameter ...
We are building a test card for a host that embeds the STM32L552 microcontroller in it. The data lines are broken out and VDDUSB is tied to the same voltage as the VDD for the MCU. Do we need to use VBUS in this case? Please advise.
Hi! I'm really new to this, so sorry if this is a dumb question, but I'm currently trying to make my STM32nucleo-F103RB work as a keyboard, i've followed a few tutorials but I have a problem when connecting my MCU because when I connect it to my lapt...
