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 28, 2015 at 19:34I have a Nucleo-F070RB and am using mbed for programming. Is there something special about PB6 that prevents it from being used as a GPIO? It appears to be configured as as oscillator output (?) at 500Hz.The code belo...
Posted on July 29, 2015 at 16:59Hi, I have an STM32L15x. Is it possible to reset the microcontroller only over SWCLK and SWDIO without the reset pin when the microcontroller is in standby mode? I can access the target ID over SWD even though the dev...
Posted on July 29, 2015 at 15:07i have done bootloader and its jumps. but i like to know what the below line exactly does, Can anyone explain exactly why we give 0x2FFE0000 and do ''and '' mask and how it works? if (((*(__IO uint32_t*)APPLICATION_...
Posted on November 21, 2014 at 19:54Hello, in xPortStartScheduler routine, the systick priority is forced to /* Make PendSV and SysTick the lowest priority interrupts. */ Some HAL interrupt drivers implement a time out based upon systick value. Wi...
Posted on July 29, 2015 at 16:14I've been developing on a NUCLEO-F302R8 but a recent change to the scope of the project has left me with a requirement for 40kB of RAM, and the part on this dev board only has 16kB. What's the best way to expand my RA...
