Hi! Can anyone tell me about the difference between TimerPrescaleSet() and TimerPrescaleMatchSet()? When do we have to call them? In what order? After which function? I am having trouble using them. I appreciate any help! Here is the example, I want to use it to extend my PWM signal period 2 times. *******.............******....... TimerConfigure(WTIMER0_BASE, TIMER_CFG_SPLIT_PAIR|TIMER_CFG_B_PWM); // 0x0001 - value according to datasheet // TimerPrecaleSet(WTIMER0_BASE, TIMER_B, 0x0001); *******............********...... I know, Ther program doesn't have much sense, but I want to
Hello, I am trying to read a pulse that is 1-2ms wide and has a PRI of 20ms. This code is producing a value of ~30000 (1.5mS). No matter what I change the prescale value to, the count is always the same. My understanding from the data sheet is that the prescaler only works when the timer is in half width mode, which I assume it is due to configuring it as a split pair. Is this assumption correct? #include <stdint.h> #include <stdio.h> #include <stdbool.h> #include <math.h> #include <string.h> #include "inc/hw_memmap.h" #include "inc/hw_types.h" #include "inc/h
