STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Hi, STM32H7B3I-DK is already in stock at Digikey. Someone from ST could tell us when the STM32H7B3I-DK and Microcontroller documentation will be available on the ST website?
I've seen improvement in FDCAN peripheral timestamping for Rx/Tx messages. However, I still find it hard to synchronize RTC peripheral among different devices with CAN, since FDCAN timestamps can't store the RTC. The closest thing it can only store i...
I use this definition #define ITEM(A,B,C,D,E,F) (((ulong32)##A## << 25) | ((ulong32)##B## << 20) | ((ulong32)##C## << 15) | ((ulong32)##D## << 10) | ((ulong32)##E## << 5) | ((ulong32)##F##))that "translate" any switch case block in a constantswitc...
HelloI am quite new to microcontroller programming.and this is my first code with my STM32F429I write the code with least help of library to learn the basic principle of microcontoller programming.This is what happened.I write a program that suppose ...
Hi, I don't really have an electronics background so this might be a silly question.Is there a reason why the ground pins on my Nucleo board (f767zi) are shorted with jumpers?Or are the jumpers only used to give the board ""feets""?I'm attaching a pi...
Hi thereI am a senior Embedded developer. 1in order to maintain my technical knowledge, I would like to conribute an open source project. Have you got any suggestions?
Hello,I am trying to do communication between Charger IC(BQ25700A) and STM32 controller by using I2C communication protocol.For taking the status of charging/discharging current of battery from charger ic,i have to configure registers in charger ic a...
Hello,We already have developed a USART boot-uploader for a project of ours, testing it on an STM32F7XX customized board. I can bring up the bootloader by init command ( 0x7F ) and get a response 0x79 ( ACK ). But an extended erase command fails to r...
Hi everybody, this maybe a very simple question but it is complex to me.Are they only needed between DMA and Memory?If we have few buffers but they are same RAM, do we need to clean/invalidate before copy or read?If a buffer is located in uncache (by...
