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 October 07, 2013 at 08:59hello forum. I am new at arm so first I want to use the GPIO. I use stm3210c-eval. and this development board use stm32f107VC. I write code like this.#include ''stm32f10x.h''#include ''stm32_eval.h''#include <stdio...
Posted on October 08, 2013 at 18:29 Hi all, I use RTC_IT_ALR of STM32F102 to wake up from stop mode. In my IRQ Handler, I do this : RTC_SetAlarm(RTC_GetCounter()+ 10); and in main : while(1){ PWR_EnterSTOPMode(PWR_Regu...
Posted on September 16, 2013 at 22:20Hi all!I am wondering if anyone has tried jumping from flash code to an entire project in internal SRAM without resetting (so no memory remap / boot0/boot1 config is required). I am working on the STM32F417, and ...
Posted on October 08, 2013 at 13:581. What is the purpose of internal regulator, to what it provides voltage - to core? What does pin vcap1 & vcap2 has to do with it. I read that 0.1uf or 2.2uf cap to connected depending on regulstor used or not. 2....
Posted on May 13, 2013 at 19:46I'm using the STM32F407 in a new design and due to a conflict of peripheral pin assignments (Why isnt there more clk pin assignment flexibility?) I cannot use the JTDO pin of the device for JTAG. I think my only option...
Posted on October 05, 2013 at 16:11 Hello everybody, I try to use USART2 with DMA, but I have two problems. Now the code just sends back the received word. The memory is word based so I use the DMA controller packing/unpacking feature. My firs...
Posted on October 07, 2013 at 18:11 Hi I'm trying to write to the Flash ROM on my STM32F3 board (256k). Erasing a page works fine, but when I try to write a word (or half word), the MCU crashes. I'm doing what the standard peripheral l...
Posted on October 05, 2013 at 00:46I was checking out the usb virtual com port loopback example provided in STM32_USB-FS-Device_Lib_V4.0.0. When I looked into the usb endpoint (usb_endp.c or usb_conf.h), it defines EP3 (OUT) and EP1(IN) as the endp...
Posted on October 06, 2013 at 23:12Hi, I've got a question about using ST-LINK/V2 to program/debug an external application: if onboard st-link can be used only for MCUs from STM32L1 series or from other series too? I'm asking because in UM1079 it is...
Posted on October 18, 2012 at 20:11To erase a sector, follow the procedure below:1. Check that no Flash memory operation is ongoing by checking the BSY bit in the FLASH_SR register2. Set the SER bit and select the sector (out of the 12 sectors in th...
