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 March 27, 2015 at 05:21I have developed a stm32f207 board for my own application. I have interfaced a 14 bit grayscale camera using DCMI. I'm then transferring this image to the SRAM using DMA. The SRAM being used is the same present on th...
Posted on March 23, 2015 at 08:53Hello. I'd like to know how to refer values of variables. My understanding is all of variables are seen in a variable scope when I stop a program, but at the moment, I can't look at some variables I defined. Could so...
Posted on March 26, 2015 at 09:02Hi,I want use I2S function on ST411I2S1(SPI1) can work on DMA Mode?I check DMA1 request mapping Only have I2S2 , I2S3 but in my design need SDIO (SPI2,SPI3) #i2s-stm32f411
Posted on March 26, 2015 at 19:01 I try this simple code to get used to EEPROM HAL drivers library, but when i try to download the code to the board and start debugging with Keil, it appears ''cannot access target. Shut down debugging session'' a...
Posted on March 26, 2015 at 15:48Dear All, I am new to an embedded world in general and to the STM32F4xx controllers in particular. In order to learn the trade, I got the STM32429I-Discovery board and along with the hardware, I have installed: ...
Posted on February 10, 2015 at 14:30Currently I'm developing a battery powered application with lcd and stm32f103 (1MB).Because a full screen update is ugly-slow on 32 MHz I'm looking for ways speed up to 72 MHz. But since this doubles the current c...
Posted on September 20, 2012 at 03:51I have EXTI example running on my stm32f4 board but I am having trouble changing the PIN which causes the interrupt. Here is the initialization method:void EXTILine0_Config(void) { GPIO_InitTypeDef GPIO...
Posted on March 26, 2015 at 15:01I was wondering what the negative input can be on an ADC pin. We have an analog signal that can be very rare -38mV for a short moment. In the datasheet page 60 of the F411 i can only find Absolute maximum ratings: In...
Posted on March 26, 2015 at 14:59Hi,I am trying to program stm32l051 MCU using IAR workbench and stlink V2 debugger.I am facing an issue while trying to program it when MCU is in stop mode. In normal mode it works fine.It is also observed that durin...
