Posted on October 06, 2011 at 15:38Has anyone successfully used the ARM CMSIS DSP library with the STM32F10x_StdPeriph_Lib_V3.5.0? I added, &sharpdefine ARM_MATH_CM3 &sharpinclude ''arm_math.h'' //for ARM CMSIS DSP to my main.c and modifie...
Posted on July 18, 2017 at 15:40Hi, before buying I preferred to ask advice to you. I am pursuing a project that has the ambitious goal of bringing analytical accounting to farms. To do this I have to automate some processes. The process I now descr...
Posted on July 17, 2017 at 23:15I am using the STM32F4 board's TIM8 in order to generate a quadrature PWM signal at varying frequencies. That is working great; however, I need to decode the signal as it is being produced, aka, count the rising edges...
Posted on July 18, 2017 at 20:05Hello. I need to use PB4 as a normal GPIO digital output pin. I�m using the HAL for developing the firmware. The code I use for configuring GPIO is:__HAL_AFIO_REMAP_SWJ_NONJTRST();__HAL_RCC_GPIOB_CLK_ENABLE();GPIO_Ini...
Posted on July 18, 2017 at 16:34Hello,I'm new to CubeMX and HAL drivers. Recently I build a test project with RTC module, but now I'm experiencing quite weird behavior of the HAL_RTC_GetTime/HAL_RTC_GetDate.In my case HAL_RTC_GetTime function can re...
Posted on July 19, 2017 at 01:26Hi,I am just getting started evaluating the STM32F0 Discovery board with the Keil MDK-ARM Toolchain. Following all the quick start guides and the STM32CubeF0GettingStarted to run the examples leads to the following er...
Posted on December 23, 2015 at 02:42Dear all.We have a project to calculate the optical flow by STM32F427.Like the following project : https://pixhawk.org/modules/px4flowBut we chose the camera OV7251 instead of MT9V034.The main problem is the inter...
