Hi,i'm using the arm_fir_f32() funktion to filter a real time input signal.My problem is, that the funktion return '-nan' for each input.#include "foc.h"#include "tim.h"#include "adc.h"#include "debug.h"#include "arm_math.h"/* FIR-FILTER */#define BL...
I have used STM32Cube_FW_L4_V1.13.0 to create a customHid device but i can't get it working correctly with PC. I get the descriptors etc. but PC always says the device is in low power state. Any ideas what might be wrong?Information from PC:[Port3] :...
I've configured I2C and I2C for reading 4 byte from a sensor. But for some reason. I currently don't have the code available here so I'd like to ask if somebody knows of an AN or has managed to receive data using DMA over I2C in master mode.Thanks fo...
Hi,I have a board with STM32F103VET6 mcu. Sometimes when power on at startup, my mcu sometimes does not start as it should start, and it only start to work when the software is reinstalled.When the problem occured, I have checked the flash data from ...
I want to achieve high sample rate into stm32f446, so I found that I can triple the sample rate using "triple interleaved mode" and DMA. I thought I can make this easily by defining each of ADC1, ADC2 and ADC3 as continuous conversion mode with direc...
When I calibrate the HSI frequency of an STM32F7 writing to HSITRIM in RCC_CR register, which is the calibration step? I mean, how much the frequency of HSI change if increasing or decreasing HSITRIM in 1?Doing the same with an STM32F0, ref. manual s...

Posted on January 21, 2014 at 14:29I use NVIC_SystemReset() in order to reset the system. I am using STM32F103 in my application and RTX rtos. The problem is that if called NVIC_SystemReset() before the RTOS started, the software reset worked. If ...
I'm using the STM32F767ZI MCU and with its RTC function. But my quartz crystal is not accurate. According to the document of the MCU, the accuracy can be calibrated (it said in page 35/255: Digital calibration circuit with 0.95 ppm resolution, to com...
