New possibilities for the ultra-low power segment!

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...

Resolved! Can anyone tell me how to configure external interrupts on stm32f103c8t6? is there anything wrong, my IRQHandler is not functioning properly...(actually, i wanted my LED(PA1) to glow when i interrupted it with push button(PB3) but it is not doing so...?

#include "stm32f10x.h"void EXTI3_IRQ_IRQHandler(void){ if(EXTI->PR & EXTI_PR_PR3) { EXTI->PR |= EXTI_PR_PR3; GPIOA-> BRR |= GPIO_BRR_BS1; }}int main(void){ RCC ->APB2ENR |= RCC_APB2ENR_IOPAEN;   //LED(OUTPUT PIN)(PA1) GPIOA->CRL &= ~(GPIO_CRL_CNF1); ...

Generate PWM N-Pulses with each different Pulse width

We need to trigger camera by using PWM with different trigger delay for each photo. i.e trigger the camera at 100ms, 120ms, 150ms, 200ms, 210ms, 240ms, 260ms, 280ms, 300ms, 350ms for taking 10 photos at each cycle and this cycle repeats. Is it pos...

arm_sqrt_f32 and arm_math.h

Hi, I'm using Cube and Makefile.I'd like a clearer run through of how to make use of the sqrt f32 function in arm_math.h.. The header doco says to copy the header to Include, done.. Then link the Lib for big/little endian. Here's where I'm stuck, how...

We are using HAL library for F215xx and F746xx MCUs. We found difference for CAN driver within HAL_CAN_GetRxMessage() function for setting the RTR (remote transmission request) register. Are more detailed information about sFIFOMailBox availalbe?

Clock Held Low Using DMA

Hello everyone, im currently studying DMA on STM boards, and im trying to send I2C messages from a mcu SLAVE (arduino) to STM32F407VET6 master, but both SCL and SDA lines is held low, it doesn´t happen when im using I2C in polling or interrupt mode, ...

STM32G4xx process technology (nm)

Hello,I would like to know the process size used in the STM32G4xx. I understand the 'F4, L4 and G0 are 90 nm and the 'H7 is 40nm. My interest stems from an application in a high RF environment, where larger process size would seem to be more robust...
