SYSTICK TASKS
- We used Software delay in our blinky, read_sw1, and read_sw2 programs. Replace Software Delay with SysTick Timer Delay.
- If we are sure the execution speed of our function is less than (224 bus cycles), we can use this timer to collect timing information with only a modest amount of intrusiveness. Use the SysTick timer to measure the Software Delay functions we used in the earlier programs.
- If we activate the PLL and change the bus clock to 50 MHz (20ns), what is the longest elapsed time we could measure?
