Posted on April 14, 2014 at 17:04Don't know if this is an oversight or normal. When I configure a pin with CubeMX to be ''External Interrupt Mode with Falling edge trigger detection'' for example, and enable the interrupt in the NVIC configuration, ...
Posted on April 22, 2014 at 14:24Hey everyone, I am using a STM32F0-Discovery with a L6470 stepper driver IC attached. As a sofwtare basis I currently use ChibiOS. I am able to command the L6470 utilizing the DMA controller for SPI data transfer but...
Posted on April 23, 2014 at 23:20Hi everyone, I'm trying to implement SPI on stm32f4discovery kit here's the code I found on some blog<b>#include ''stm32f4_discovery.h''#include <stm32f4xx.h>#include <stm32f4xx_spi.h>void delay(uint32_t cnt);// this...
Posted on September 03, 2013 at 17:02Hi,I'am starting a new project and I will need to interface the STM32F4 discovery with a camera module (OV5642) via DCMI interface. (I won't use an LCD module).I will need a high resolution photo (>1024 pixel). I...
Posted on April 23, 2014 at 07:04hi guysi could produce pwm in stm32f407 but i don't know how to read pwm with this.if i have 9 channel pwm i think i takes 9 pin from servo and if i can send this 9 pwm through 1 ppm(Pulse Position Modulation) channe...
Posted on April 23, 2014 at 11:17Hi all,I am trying to use low power modes on STM32L100 MCU.I've implemented a simple firmware that after setting the MCU to run @32MHz (HSI+PLL using the Clock Configuration Utility excel) waits an EXTI (key pressure...
Posted on March 31, 2014 at 10:45 I am using the TIM1 in the stm32f4 in encoder interface mode to get position. The two chanels of my rotary quadrature encoder are connected to the pins A8 and A9 through a comparator. The outputs from the compar...
Posted on April 23, 2014 at 10:00Good Morning,I am a new user on the forum.I am working on some digital filter implementation on STM32F303, mounted on a discovery board.I have found that the prototype of the function arm_provide_guard_bits_q7 is mi...
Posted on March 21, 2014 at 20:04Hello;I am tryin to implement the Timer function using the General purpose timers TIM1 and TIM2 of the STM32W108 ARM Cortex M3 controller.Following is the initialization code for the timer 2.void timer_init(){ TIM2_...
Posted on August 29, 2011 at 17:31Hello at all... I'm developing a camera that acquires a frame when it has a trigger and stores the data in the external ram with the DMA. The camera has a relolution 1280 x 1024 pixel (each one of 16bit) and all pin...
