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 August 13, 2017 at 02:27Greets All,I am trying to set up I2C communications between a nucleo STM32F411RE board (as master) and a STM32F103C8T6 Blue Pill board (as slave). I am using cubeMX and Keil. I also want to use DMA. I want to set th...
