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 01, 2013 at 13:52Hi, I have tried to measure the real output voltage on 5V pins so I'd know for sure I won't burn my servo, but after doing so all LEDs went of, nothing happens after connecting board to USB and now on the 5v pin I h...
Posted on July 31, 2013 at 09:26Hi,I am trying to use internal temperature sensor of STM32VLDiscovery board but I have a little problem. I get ADC conversion result and apply the formula in RM0008, temp = (V25-Vsense)/Avg_slope+25, to calculate temp...
