WebApr 2, 2011 · Another way to do this is to build just one oscillator, or simpler BUY one oscillator, say 40MHz, and use logic devices such as binary counters to generate the other frequencies. With one counter you can get frequencies (in MHz) of 20,10,5, 2.5, and with an 8 bit counter even more than that. WebFosc = 20 MHz = 20000000 Hz Therefore, Timer frequency : Ftimer = Fosc / 4 = 20000000 / 4 = 5000000 Hz = 5 MHz If Prescaler =1:32, then Ftimer= 5000000 / 256 = 19531.25 Hz So, the TMRO register value = 256- ( (Delay * Fosc)/ (Prescalar 4)) = 256- ( (1ms * 20Mhz)/ (32*4)) = 256-156=100 The values are reloaded again to start timer for same delay.
