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...
Hello All, I came across the daylight saving feature in RTC peripheral of STM32F401RE. I live in a country where there is no concept of daylight saving, hence this is new to me as well. As per the RM of STM32F401RE, there is a automatic daylight sav...
I have been working on a F103 project for a few years. Recently I set up a new computer and copied my source code there to work with. I was able to build and run my project on the new computer just fine for a few months.Today, I wanted to do a quick ...
Hi, I am using the Nucleo - L152RE board and I am having a problem with the UART1 interrupt.The output to Teraterm works fine, but it does not go to the interrupt and the code terminates. Can you tell me what the problem is? /* USER CODE BEGIN Heade...
Does i++ or ++i matters in loops in terms of processor cycles consumed in STM32H723 MCU?Using CubeIDE. Optimization: O0
Hello,my goal here to understand the TIM channel output behavior in different situations between generating one-pulse. Ultimately I need to make sure that I have a predictable output "0" level output at all times if not generating pulse.I am using ST...

Hi Sir,I'd like to choose STM32F103V/R/Z to achieve the USB to 4UART and I2C in my system.Because it's said this MCU's USB support up to 8 bidrectional end ports. I don't know whether it's right or not.Could you help to review it or propose another s...
How can you write a program that updates itself for an STM32, eg. for an STM32F103C8?I'm not talking about a bootloader, since (as far as I know), a bootloader lives from (say) 0x08000000 to 0x08001000 in Flash and then updates another program (anoth...
Hello!! I'm trying to use both CAN peripherals in an STM32F446RET6R on a custom PCB, but something is not going well enough. I've done the basic configuration using the STMCubeIDE platform (I'll add the code later, but first I want to know if someone...
Hello,I am trying to implement the following: a timer (tim3) is set to PWM generation, outputting a pulse periodically. Its TRGO triggers the DMA channel to request I2C to initiate a read transaction, read 8 bytes and generate an event interrupt (TC ...
