Posted on October 04, 2013 at 22:58 Hi, i've been looking around for a solution to this for some days now, but nothing, maybe someone of you can help me. I have the following code: TIM_TimeBaseInitTypeDef TIM_TimeBase_InitStructure...
Posted on October 05, 2013 at 04:14 TIM6 Update event occurs each 37.5MHz/256 = 16.406 KHz the words in the DAC exemple. I want to know how to get the 37.5MHz ,how to calculate it out.Thank you for your help.
Posted on July 29, 2013 at 15:49help again, I work with a four-timer but it does not work the channels one, two and three. I initialize them but they do not give a PWM.CH4 working very good!My code:void init_pwm( void){ TIM_TimeBaseInitTypeDef TI...

Posted on October 04, 2013 at 11:13I have found working solution. But for me it look ugly.uint8_t command = 0x55; uint16_t u16Temp = 0; u16Temp = GPIO_ReadOutputData(GPIOA)&0xFF00; u16Temp |= command; GPIO_Write(GPIOA, u16Temp); Is there better way ...
Posted on October 02, 2013 at 11:24Hi all,I probably made a mistake in my first layout for STM32F103RE (LQFP64), with SDIO bus. My 400 KHz SDIO_CLK output is not consistent on oscillo : I see variations in the levels of the HIGH and LOW that vary wi...
Posted on July 18, 2012 at 19:59 Hi Friends from ST and dear fellows. I'm using STMStudio with yagarto toolchain and STLIB with the STM32F4Discovery. Up to release 2.2 of STMStudio I was able to import any global variable avaliable from inside...
