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 17, 2013 at 09:58Hi , Maybe someone here can help me with the issue that i am having . I am currently evaluating both embOS and OS-III on STM32F4G-Eval, and i see the same issue on both of them . After starting my task , when inside ...

Posted on July 17, 2013 at 11:47Hello all,I've been trying to convert JPEG files to BMP for over two weeks. I have STM3240G-EVAL which includes IJG's JPEG library in its ''demonstration builder'', however, I could not figure out how to use it. All I...
Posted on July 18, 2013 at 21:19Hi, I have Problems with STM32F407VGT6 and SPI, I read from SPI 2x 16-bit words from device. In documentation is written after the first word is read then wait for short period that th one clock cycle starte then disa...
Posted on August 31, 2012 at 01:02I'm trying to use RMII between an STM32F407VE and an SMSC LAN8720 PHY. So far I've followed along with the STM32F4 Ethernet example but am having less than stellar success.As far as I can tell, MDC and MDIO go low a...
Posted on July 23, 2012 at 22:26 hello, i am trying to make interrupt based touchscreen program, but have no luck connecting GPIOB_pin12 to interrupt line i was able to do so in GPIOA_pin1, but still cant figureout how to do that on GPIO...
Posted on July 15, 2013 at 18:50Hi , I am working on Cortex M4F CPU , its 168 MHZ , i know that Cortex M4F is 1.25 MIPS per MHZ so a quick calculation will give me total of 210 MIPS . Lets say i have an algorithm that runs 3 seconds , so what shou...
