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...
Posted on January 30, 2017 at 18:10Hi all:I used the device as a data logger, wake up from shutdown mode if the nucleo RTC alarm goes off on 29 minute every hour.But it seems the system RTC display wrong time before the device enters shutdown mode....
Posted on January 30, 2017 at 21:56Hi,I have a few questions about osxAcousticEC:1. I need the AEC profiling. Doc UM1966 says I can find the information in osxAcousticEC_Package.chm, but I really could find anything about the MIPS, RAM and Flash. I ...
Posted on January 30, 2017 at 19:38The reference manual, RM 00090, does not explicitly stay what happens to the GPIO lines when STOP mode is entered. If a pin is high, does it stay high?#stop-mode #gpio
Posted on January 30, 2017 at 20:38I've configured DMA for Tx and Rx on USART 3 on an STM32F4. The device on the other end is a Bluetooth module. I am, for some reason, receiving my transmitted command back as a reception. Is this expected behav...
Posted on January 30, 2017 at 19:00Hi Good morning, I am planning to use ST Bluetooth module SPBT3.0DP2 with stm32F20x microcontroller for my application.I understand that the Bluetooth module supports the UART communication and works with AT c...
Posted on November 28, 2015 at 04:51First of all, forgive my poor English As title indicated,I want to propose two issue I confront in my work.Before that,I would like to introduce the function I was supposed to achieve briefly. In my project, I use...
Posted on January 24, 2017 at 19:14While researching a project I measured the output of STM32F373V8 DAC and had a hard time considering whether it is Ok.Reading the latest Reference Manual (June 2016 DocID022448 Rev 5) for the MCU found a formula fo...
Posted on January 30, 2017 at 12:53Hi all,I'm trying to setting up the SPI interface on my STM32F091, I would use the SPI1 on the PB3&PB5 pin.This is my simple code:RCC->APB2ENR |= (1<<12); GPIOB->MODER |= 0x880;GPIOB->OSPEEDR |= 0xCC0;SPI1->CR1 = S...
Posted on January 30, 2017 at 14:49HelloI tested stm32cubef3 (rev 1.6&1.7) ADC_DualMode_18Msps example with stm32f3 discovery board, i applied a 100KHz pwm wave to pc1, captured 32768 samples and calculated conversion rate by counting the number of ...
Posted on January 30, 2017 at 13:50Hi, I am using the NUCLEO-F411RE eval board.I used the STM32CubeMX to generate the API's for USART with interrupt.I am using System Workbench for ECLIPSE as my IDE.I have used the USART2 for full duplex communicati...
