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...
Posted on July 23, 2017 at 10:57Hi!when I tried to run the code below at an interrupt it took 123u sec! (I measured that by toggle PGIOB7) which is too big for me . any one can advice?I am using STM32F429 running at 70MHz (I can't increase the clk f...
Posted on July 23, 2017 at 16:18Hi all , I used BlueNRG-MS found a problem , the MCU is freescale chip and used SPI communcation with BlueNRG-MS , but the MCU send the configuration information to BlueNRG-MS , start I could read 0x04 0xFF 0x03 0x...
Posted on July 23, 2017 at 10:33Hi there,The idea is to use the same driver pins for PMSM(FOC based) and BLDC(own library) motors. FOC SDK 4.30 allows to initialize the same pins for only one type of motor (PMSM in my case). Is the any way to stop/d...

Posted on July 17, 2017 at 12:37HeyI'm using stm32f103c8 and I want to use all of the GPIOB .it work good expect pin 3 and 4.Those pin use for sys_njtrst and sys_jtdo-tracswo but i just use SW and i don't need these pins for programming and want to...
Posted on July 20, 2017 at 00:15Evaluating the above processor using gcc toolchain and openocd and J-Link. Not using cmsis (various reasons) and writing all the low level hal and header files, as a way to become more familiar with the processor. Alr...
Posted on July 21, 2017 at 17:30example provided on STM32Cube package for STM32-Nucleo are based on LL drivers. I think I miss something in configuring the board using HAL functions. Thanks !
Posted on July 21, 2017 at 23:36Greetings,After reading http://www.keil.com/support/docs/3777.htm it seems like a good idea to change the SDRAM attributes via the MPU. Can anyone comment on the performance impact of enabling the MPU (it's not curre...
Posted on July 21, 2017 at 20:46Hi,I'm writing a code that works fine when I program directly via Keil with this settingsHowever if I compile the project and write hex file with stm32 st-link it doesn't work fine. It is good to mention that I active...
Posted on May 22, 2017 at 16:17Hello everyone,I already successfully used the LTDC to create a VGA Signal with a Resolution of 800x480 Pixel with 16bitcolour with decent performance. All configuration was done with CubeMX for the LTDC.AN4861 claims ...
