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,I'd like to connect EEPROM slave to I2C2 of STM32F767 MCU. EEPROM's supported clock is 1MHz. With 25 MHz HSE, I only managed to setup PCLK to 1.5625 MHz. Am I correct that it is imposible to setup I2C2 to 1 MHz with this setup?Thanks!
Can you please help me to get quick link to download STM32479I-EVAL demonstration software? I can see related resources but unable to find the demonstration software.
MCU is STM32F405. I write data array to output pins using DMA mem to peripheral (DM2 stream6 channel0). Trigger is TIM1 CC1 event. Also I use DMA2 stream5 channel6 for write to TIM1 registers. Trigger is TIM1 UEV event. So the writing and interrupt D...
Hello, I am trying to communicate with an SMBus battery. That has 2 sections so I am using 2 I2C modules. There was this problem: After the first I2C module makes a successful communication second module gets stuck. And it gets stuck in Busy. So I ch...
dear all,I keep studing the STM32H7 architecture and this time I am trying to control a DAC using DMA which seems an easy task. However, in my case, the output is always at zero. I have used it without DMA and it works, therefore my HW debugging work...
Hello,Recently I started using c++ application with STM32, and I encounter a very strange behavior:It seems that after 1-3 calls to new() operator the new operator call get hang somewhere into assembly. When I try to step into the problematic new cal...
I am try to connecting a STM32 Nucleo (F401RE) to a ESP8266 on UART.I've managed to control the ESP8266 with the PC using a usb/uart channel and hyperterminal.I've managed to send uart messages to the PC from the NucleoBut I am unable to command the ...
We have a driver for the RTC which I am trying to enhance with sub-second resolution.I am testing with a tight loop which is repeatedly reading the time. First I am reading the SSR register (which should 'lock' TR and DR?) then the TR, then DR (to 'u...
Hi,In one of my project I am using STM32H750 controller.I want to measure the pulse width which is an input to the controller whose width will be in some nanoseconds so I want to configure the timer in a way that it can support to start the count fro...
