Posted on December 04, 2015 at 07:07for the SAI example in cubeL4, it looks like running 22050 sample rate, and the input clock is 11.294M. I measure the frame len is about 45us which is 1/22050. Now I develop an audio app runs 44100, I have checke...
Posted on December 04, 2015 at 15:33Hi. I have to do some calculation, where I need to be precise and have to use sine function. I do that calculation only once and speed of execution here is not so critical. So I dccided to use floats (before I had...
Posted on November 24, 2015 at 21:09I work in CubeMX. I want to trigger my timer interrupt (period elapsed) on some speed. To fill up proper prescaler and period I need to know bus speed, on which this timer is. Is there quick way to get it, without...
Posted on December 04, 2015 at 18:03The GPIO mode can be defined for analog mode:1) GPIO_Mode_AIN2) GPIO_Mode_ANwhat is the difference? In what cases one mode is better than the other?Thanks.
Posted on December 03, 2015 at 23:19Hello ; I am new to the forum ; sorry for my odd quastion ; but since ST dont post the prices of thier controllers like TI , freescale and microchip ; so I need to ask this question here ; I am switching my desig...
Posted on December 04, 2015 at 15:47 Hello, i need to implement hardware triggering by TIM8 ( as example) that will copy PWM table to TIM1->CCR1,2,3 Idea is, i want to turn 3phase motor with 3P_PWM +3N_PWM outputs (3H bride so 6lines...
Posted on December 04, 2015 at 15:51please add oryx-embedded library to cube. that library support external PHY like enc28j60 .
Posted on December 02, 2015 at 14:05hii have configurd to get an interrupt nce the timer update . But it did not work, can anyone knows whats the problem.I am using stm32f429 discovery board... void timer_init() { /**** clock for the timer *****/ ...
Posted on December 04, 2015 at 07:58Hi,I called HAL_Delay(500); but inside the function, the return value of HAL_GetTick() is zero. What can be wrong? Thanks in advance.EDIT : oops, when I set a break point at line A below, I see tickstart is always...
Posted on December 04, 2015 at 11:14Hi i am using coocox ide .i have configured for Stop mode by using some examples and it wakes up by using the rtc wakeup interrupt. The mcu wakes up and goes to the rtc_wakep handlar. the problem is, it is not con...
