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 July 28, 2014 at 22:01�My hardware guy� bought 2 Olimex H-405 boards. (He wanted 64-pin QFP.) Code loads and runs using an external ST-LINK/V2 and its 20-pin cable. Or rather runs some then freezes.After setting SysClk to 168 MHz then set...
Posted on July 25, 2014 at 18:47I have used WFI() previously, but I can't figure out what is going on with my current code. The WFI() returns immediately, but I can't figure out what interrupt is active. Any tips for determining what caused a WFI(...
Posted on July 28, 2014 at 01:25I have two different projects: one based on the '205, one on the '427, Both use identical USB libraries from ST. They are both set up as FS devices using the internal USB PHY. The issue I am seeing is that in the '205...
Posted on July 27, 2014 at 15:28When I using my desktop computer to power the STM32F429i Disco, the PWM out put amplitude is aobut 3v, but when I use a IC LM7805 (change DC form 9V to 5V) to power it, PWM reduce amplitude obviously, even just have 1...
