Systick timer is a dedicated hardware-based timer which is built inside the ARM Cortex M4 CPU and can be used to generate an interrupt at a fixed interval of time. As shown in the figure below: The systick timer will generate interrupts after a specified time and time settings can be done using the Systick … See more TM4C123GH6PM provides a 24 bit timer. Therefore, the maximum value that can be loaded to the load register of system timer is 2^(24-1) which is . Hence, it starts decrement value by one from its initial set value and generates … See more For example, the frequency of the clock given to the systick timer is 10MHz. Therefore, the time period will be T = 1/f = 1/10MHz = 0.1us. That means, the value of the counter decrements after every 0.1us. By using this … See more Let’s make this calculator for TM4C123G microcontroller. As you know that TM4C123G has 16MHz of clock bus and we want to use a bus clock.

This is the correct way to do it for most Cortex-M based microcontrollers (do not use SysTick!): Set up a timer, which runs at the same speed as the CPU. Do not attach an interrupt to the timer. Poll the timer value by using a single LDR instruction before you start your measuring.
