Posted on September 16, 2012 at 20:51Hi All;For people who interested by connecting a mouse or a keyboard to the STM32F4 Discovery:Attached a project that I have ported from the example provided in ''USB On-The-Go host and device library'' that work...
Expanding on ISRs generated by CubeMX
Dear AllCubeMX (Clive, I know you do not encourage relying on it, but please bear with me for a while) adds many c and h files to a project. Is the programmer allowed to modify any of such c files other than the main.c? For example, I see a void SyST...
HAL_PWR_EnterSLEEPMode() needs to have a __DSB() before the __WFI() or __WFE() according to ARM documentation
According to ARM Cortex-A Series Programmer’s Guide for ARMv8-A:15.1.2. Standby...This mode is entered using either the WFI (Wait For Interrupt) or WFE (Wait For Event) instructions. ARM recommends the use of a Data Synchronization Barrier (DSB) ins...
ROS spinOnce jamming the process of MCU
We are using ROS Serial to let Raspberry Pi and STM32F103C8T6 communicate with each other. And there is another UART channel for IMU to use. We observe that the spinOnce function of ROS jammed the process of MCU. Therefore, other work cannot operate ...
STM32H7 series resistors in data lines ?
With a 400MHz clock and very high speed ports, I was assuming the faster data lines would need series resistors to avoid reflections in the way things like FPGAs do. But I've just noticed the evaluation board doesn't have any and routes even high spe...
Is the backup domain operates directly out of Vdd or Vbat ?
Microcontroller used : STM32F779NIQuestion: [1] My understanding is that the backup domain is directly supplied from Vdd or Vbat (When Vdd is removed) without any regulation (1.8V to 3.6V). Does this means below blocks can operate directly using Vdd...

STM32 Flash Loader Demonstrator - Support for STM32H7X3
The current Flash Loader does not support the STMH32H7XX family, can we hope to have support soon? The PID is 450 , It is relatively easy to fabricate a .STMAP but the option bits need to be somehow supported by the application
Need help using SPBTLE-RF standalone with SPI functions
Hello ST Community,I am currently working on a prototype using a SPBTLE-RF module for Bluetooth communications. The module is connected with a SPI bus to a STM32L476VGT6 MCU to control it.The problem is, I didn't find anything in the documentation ab...
