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 October 27, 2016 at 19:26I've been making a device on STM32F407VGT6 That uses UART with both DMAs, DAC, few GPIO and Timers After some time coding it, ive came into shocking situation. DAC have become inverted! If i send 0, it sets 3.3V, i...
Posted on October 28, 2016 at 14:57Hi, I�m not allowed to configure some port E pins. RCC_AHBPeriphClockCmd(RCC_AHBPeriph_GPIOE, ENABLE); GPIO_InitTypeDef GPIO_InitStructure; GPIO_InitStructure.GPIO_Pin = GPIO_Pin_2 | GPIO_Pin_3 | GPIO_Pi...
Posted on October 28, 2016 at 15:09Hi!I have a firmware that works only after Nucleo flashing (using System Workbench). After the flashing if I disconnect, and reconnect microUsb of Nucleo, the program doesn't work anymore. This is not the first tim...
Posted on October 26, 2016 at 03:00Hello, I trying to make IR transmitter with STM32F4DISCOVERY demoboard and found in http://stmcufinder.com/wp-content/uploads/training/STM32L4-WDG_TIMERS-Infra-Red-Timer-%28IRTIM%29.swf that it F4 MCU should have b...
Posted on October 18, 2016 at 16:47Hi, In some condition ERRI Interrupt occours without any other error condition (CAN_ESR = 0). What is the meaning of this interrupt? Thank you. Alessandro
Posted on October 28, 2016 at 14:34Hi All. Looking at the STM32F7 Series main page I read: ''STM32F7 series is pin-to-pin compatible with the STM32F4 series''.Now, I would like to find a device pin to pin compatible with the STM32F407VG I am current...
Posted on November 23, 2013 at 01:22Hi all,I'm recently building an application which asks for the current analog input at each poll. It only reads the ADC value when it receives the request, which means that my STM32L will not read the ADC value a...
Posted on June 18, 2011 at 19:13Hello, just expierenced some strange problem. My app should go to Stop Mode and wake up when a signal on an EXTI line is detected or every 10s by RTC wakeup. Without the RTC wakeup everything works fine, but when I ac...
Posted on October 27, 2016 at 22:50 Hi All! Edit : i'm using dicovery board STM32F429I-DISCO. i'm tying to combine 2 examples from ST CUBEF4 Firmware Package V1.10: 1. TIM - peridoc activity, every 0.5 seconds toggle LED3. 2....
