Posted on June 12, 2017 at 00:54Hello:According to all the documentation I can find, I have configured the STM32F4 correctly to interface to the H3LIS200DL accelerometer. This is for use in SPI3 (AF6). Somehow, there's still something amiss. When I ...
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 ...
