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...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Posted on November 15, 2012 at 18:53First i had problems with the ST-Link drivers, then I had success with installing them. Now I get ''core is held in reset'' error in st-link utility.How to fix this? My only idea is that I shorted something when I...
Posted on November 15, 2012 at 19:33Hello,I am new to debugging on the STM32 and I have a STM32L152-EVAL board and I am trying to bring up the new open source version of RTX on this board. My setup is as follows.This is setup on a Mac running Mount...
Posted on November 15, 2012 at 17:01Hey Folks, I know it is possible to reset processor with NVIC_SystemReset(). However, is it possible to enforce a _full_ power-off -> power-on reset from inside the code? Cheers
Posted on November 11, 2012 at 18:12Is there an inherent reason why activating EXTI0 using PA0 would interfere with a previously functioning I2C1 transmission operation? (Atollic TrueStudion Lite) That is, I tried to add ext interrupt from previous...
Posted on October 31, 2012 at 20:26Hi, i tried to use IAR example about LCD for use my display hd44780. I connected 6 pin (RS,E,DB4,DB5,DB6,DB7) for use it on 4bit configuration (i'm sure that the connection is good cause i used that on my old ardui...
Posted on November 12, 2012 at 02:43Hello,i need help about designing a stm32 project. Thought is follows. (i must not use any RTOS)1. my stm32100 will handle uart interrupt randomly2. my RTC on stm32 will be updated each 1 second in the rtc interru...
Posted on November 12, 2012 at 17:22I need that display that I put on my stm32f4 Discovery is updated every second, I thought to do so through an interrupt TIM, but I do not know how to configure to work as TIM clock! can you give me some suggestion...
Posted on November 13, 2012 at 21:25 Hi, I have enabled external interrupt (EXTI) by connecting to pin PA4 a button, with its pull-up (I also tried the pull down) but when I pressed the button sometimes is performed twice Iterrupt routine (or mo...
Posted on November 13, 2012 at 22:44With help from this forum, I've developed a lab course using the STM32VL Discovery board over the past year. A draft of the lab manual is available athttp://www.cs.indiana.edu/~geobrown/book.pdfan overview of th...
Posted on November 14, 2012 at 11:35 Hello, i am trying to config adc for single convertion. Idea is to config two ADC for reading photodiode array voltage, one adc channel for odd pixels, one for even pixels, and do complex math with adc re...
