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...
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 ...
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...
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...

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
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...
Posted on January 31, 2018 at 11:17Hello everyone,after update of STM32CubeMX it started to generate simply uncompilable code for TrueSTUDIO.When I select FATFS od FREERTOS and TrueSTUDIO as a IDE, after compilation,functions like HAL_Init(), osThre...
About to put my first device in the programmer and don't want to make a mistake. Datasheet says there is a round mark in the corner near pin 1, but of course the package has two round marks on diametrically opposite corners. With the writing correc...
