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...

How to round division on STM32G0

I'm trying to implement an integer division with rounding. Obviously, by default integer division does floor and I was thinking I could use the remainder to determine if I should add 1 to my result.Processor cycles are at a premium in this solution (...

I want to develop a C program on the STM32F303 board that uses the SPI interface where the microcontroller is the master and the L3GD20 gyroscope is the slave: I want to perform a transmission to ask the gyroscope to provide me with the x, y, z coordinate

Considering that the gyroscope's chip select is the PE3 pin, how should I do this? The program below doesn't work#include <stm32f30x.h>void GPIO_Config();void SPI_Config();uint8_t L3GD20_Read(uint8_t reg);void L3GD20_Write(uint8_t reg, uint8_t data);...

STM32U5 ADC1 bulb sampling multiple channels

Hello,I am using ADC1 on STM32U5 to sample two channels periodically using the DMA and a TIM6 trigger. I am doing this in bulb mode since I would like for the ADC capacitor to charge for the entire duration.I had thought that the ADC would sample th...
