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 May 09, 2014 at 15:48Hi, Has anyone started using V1.0.7 Keil.STM32F4xx_DFP.1.0.7.pack? We are considering to use it as a part of medical product development. I also do not see any example codes as a part of this pack (particularly requir...
Posted on May 09, 2014 at 12:25Hi all. I'm trying to work with ADC and DMA. The adc works, i'm able to read directly value form pin PC1. When i try to read it using DMA a get alway zero value. I'm try to get work example from stm32f4_dsp_stdperiph_l...
Posted on May 08, 2014 at 17:48Simple question - should be answered in datasheet, errata sheet, or ref manual but I cannot seem to find it. I am wondering how much ADC readings drift relative to the reference voltage with temperature. If I have a co...
Posted on May 06, 2014 at 07:17Is there a tutorial or lecture series for beginners working with a STM32F3 demo board? I have programmed simple project boards like Arduino, but not anything like the STM32 boards. I have tried to work backwards from t...
Posted on May 06, 2014 at 00:33Dear, i have the following issue: i have seen that i cannot process too many instructions from inside interrupt. I guess there is a limit. (still didn't looked the datasheet), So i decided to do just some few operatio...
Posted on May 08, 2014 at 20:36 Hello, I'm trying to use the PC13 as an output but I can't get any signal change from it. I'm already setting the pins PC14 and PC15 as inputs following the datasheet orientations. I used one of the ...
Posted on May 08, 2014 at 11:57How could I write some code that would access a memory address and wouldn't generate a bus fault if it was incorrect? Or failing that, is there a way to safely check if an address is valid, or maybe even a way to have ...
Posted on April 16, 2014 at 12:36 Hello, I use a STM32F427 running with FreeRTOS. I try to create a file on my SD card, through SDIO, thestm32f4_discovery_sdio_sd.c (DMA mode). I also use the librairyFatFs R0.09, ported by Clive I ...
Posted on May 08, 2014 at 14:37Hello! Is there any goal in use a 32 bit SDRAM memory VS the 16 bit SDRAM memory on STM32F439 device? I want to transfer a 30 fps video from DCMI to 4.3 LCD. Wich SDRAM will be faster? 16 or 32 bit?
Posted on May 07, 2014 at 23:04I am trying to build a scheduler on top of a 1MHz tim5 32 bit timer operating in one pulse mode:void initMicrosecondTimer(void) { RCC ->APB1ENR |= RCC_APB1ENR_TIM5EN; // Enable TIM5 clock nvicEnableVector(HW_...
