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...
Dear ST Community,We have an old PCB with a ST10F269 chip on it.We would like to upgrade our PCB with a more recent STM32 chip.Could you please recommend us which chip of the STM32 family is compatible or closer to the old ST10F269? We want to apply ...
Hi,I currently have a STM32L4R9VI (that contains the DFSDM + DMA) and I am planning to sample an IF signal ( up to 10 MHz frequency) using an external Sigma Delta Modulator AMC1305M05 (20Msps - 20 MHz frequency - 16 bits resolution). I am not an expe...
HelloI can read mpu6050 via I2c1 in stm32F4Disco but I cant read mpu6050 in STM32F746 Touchgfx.All values returns 0.This is my reading code. it is working in 32F4DISCO:#define MPU6050_ADDR 0xD0 #define SMPLRT_DIV_REG 0x19 #define GYRO_CONFIG_REG...
Interfaced i2c_lcd with stm32f401re and try to program without any library .but getting junk data always,tried changing delay but same. void I2C_WriteData(uint32_t data){ uint8_t data1=0,data2=0,data3=0,data4=0; data1= data & 0x000000ff; data2= ...
Hi i am unable to see SCL,SDA signals in logic analyser. Connected Pullup resistors to Scl,Sda pins. Interfaced with PCF8574 IC (I/O Expander) ,Hardware Connections are fine but i am not getting even clock(scl) in STM32F401RE#include<main.h>#include<...
While I was looking for H7 DMA data,I saw the article below that DMA is not working on the H7 device.https://community.st.com/s/article/FAQ-DMA-is-not-working-on-STM32H7-devicesSolution 1 from that article is shown below.--------------------------...

Hi All,To get around a problem I was having with timer capture using DMA (another topic) I changed my timer code to use interrupts. The seems to work when I debug step through it but not when I run. I am using TIM8 in input capture mode for CH1 and C...
The STM32H743 datasheet says nothing about clocking the timers. Reference manual has a chapter dedicated to each timer's counter clocking. For each type of timer the only clock is so called "Internal Clock" CK_INT . What is it? Opened my project's Cu...
Hi, I'm trying to execute an interrupt with the pin PCO with stm32f303re Nucleo board, but the interrupt routine never executes, actually, it just stops the program. this is my configuration code for the interrupt: //set gpioc 0 as interrupt _...
