Posted on October 11, 2017 at 23:35Hello,I am having some difficulties wrapping my head around what's happening with my TIM3 interrupt. I am creating a timer class for my application. It needs a 1 microsecond resolution. For some reason I can onl...

Posted on October 17, 2017 at 22:35Thank you to you both, Clive and Joerg. Clive provided exactly the solution I am seeking:500 KHz 1us width, Prescaler = 0, Period = 215, Pulse = 108 (50/50 Duty), PWM Mode
Posted on October 17, 2017 at 19:02Hi Joerg,Thank you for providing the report. I too was able to get a 2us pulse width, originally. My desire is to get a 1us resolution (ie pulse width). If this is not possible then is there an explanation for t...
Posted on October 16, 2017 at 19:58Hello,Thank you both for the analysis. I took the existing example for TIM3 from the STM32CubeF7 example project and verified the clock source for TIM3. In this case TIM3CLK = PCLK1*2 where PCLK1=HCLK/4. Using t...
