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 14:07Has anyone managed to get the STM32_USB-Host-Device_Lib_V2.1.0 to work with Sleep mode on the STM32F405 ? Does the USB clock disable work ? I have already applied the fixes from https://my.st.com/public/STe2ecommuni...
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_...
