Posted on May 17, 2011 at 13:12 I solved the problem :-] using a function to devide the tim clock, for 655535. Now the frequency step is around 0.016Hz. I'm able to measure the 40 Hz. TIM_PrescalerConfig(TIM2, 0x1987, TIM_PSCReloadMode_Immediate); T...
Posted on May 17, 2011 at 13:12 The PSC is used select the numbers of envents to capture, I wanna only one envent(the period to measure the frequency). Quote:On 25-05-2009 at 14:36, Anonymous wrote: Try this: Code: <BR><BR>TIM2->PSC=(u16)iPrescaler...
Posted on May 17, 2011 at 13:12 I`m using the st code example ''PWM_Input''. It's working perfect, but the problem is the minimum frequency to measure is 1100Hz. I wanna to measure frequency starts with 10Hz. How can I modified this example to meas...
