Posted on December 04, 2015 at 00:15Hi, I'm new to using both STM32Cube and the FreeRTOS it provides support for, and I am trying to follow the tutorials and the FreeRTOS manuals online to create 2 separate tasks to manage the two I2C busses on our...
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 .
