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 June 11, 2017 at 20:31I am trying to use 2 usart in my program. When i am trying send_to_uart2('a'); nothing happens. In debug mode USART2->SR is always 0x000. Why?#include 'stm32f10x.h'#include 'stm32f10x_gpio.h'#include 'stm32f10x_rcc.h'...
Posted on June 10, 2017 at 21:18Let us say for the purposes of discussion that I have external interrupts on PA08 and PB08. The callback is passed a pin address. How do I tell them apart if they're both the same pin number on different ports? Or doe...
Posted on December 28, 2016 at 18:42Hi All,Maybe something went wrong on the new FirmWare template, because it generates the make command without double quote around __weak= and __packed= switches like this:arm-none-eabi-gcc -mcpu=cortex-m4 -mthumb...
Posted on April 21, 2017 at 22:29Greetings,I am new to STM32-MAT code generation. I made 2 small models and they are working as expected.However, I found a big issue when I try to build a more complicated model - there is no variable (memory copy) i...
Posted on August 21, 2015 at 18:01I'm just starting with cube MX and free KEIL toolchain for STM32M0, wich includes free ARM CMSIS RTOS, and I have to say that I'm a little disappointed so far with RTOS implementation in MX. The only OS support is f...
Posted on January 15, 2016 at 15:25I need to read from a device with a variable length response, where the length of the following data is specified in the first byte received. I don't see a way to accomplish this using the HAL, as it appears you n...

Posted on June 10, 2017 at 12:58HiI am using stm32f103 to drive a BLDC motor with hall sesnors, I have found that stm32f103 has hall sensor mode to detect the motor posostion. how can I use this capability of stm32?* I am newly learning stm32 tnx
Posted on June 10, 2017 at 03:25I think I'm not understanding the terminology, or something. I want to generate an external interrupt at a pin, when timer 2 overflows. I can generate an interrupt with the timer/counter just fine, it's the output to ...
Posted on June 09, 2017 at 18:02I used to hear that one might as well make function parameter ints or the native size as chars and shorts would be promoted before going on the stack.But now we have fast variables, etc. Does it still make a differenc...
