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 22, 2016 at 12:46Hi, I have two interrupt with different pre-emption priority.When the higher priority interrupt handler is executed, I would like to ''kill'' the lower priority interrupt handler, if it was running.is it possible?Tha...
Posted on March 22, 2016 at 15:11 I am working with the Discovery Development Board and I am trying to understand how the SPI with CRC enabled works. I had a look at Application NoteAN4187 (www.st.com/st-web-ui/static/active/en/resource/technica...

Posted on March 22, 2016 at 13:35Hi, I have board with two mcu (stm32f072 and stm32f031). I would like to flash f031 by f072 via UART to easier support and only one firmware. Is somewhere example?
Posted on March 22, 2016 at 12:36DEAR ST: Participating in your forum, helping other people is ''enjoyable'' as long as the technology does not get in the way. So if I have something to say, I want to post it. What absolutely pisses me off is that I...
Posted on March 22, 2016 at 10:12 I have recently reversed-engineer some HAL source code and I see that sometimes a temporary variable is used to manipulate a register, for example uint32_t tmp = 0; tmp = hdma->Instance->CR; tmp |= hd...
Posted on March 21, 2016 at 10:56sdram clock run in 90MHz;LCD clock run in 24MHz.it not work(display ng).but LCD clock run in 18MHz,it work(display ok),but it looks blink,because reflesh rate low.huw to solve it?
