(C programming) After completing the lab, students will be able to use the GPIO peripheral for both in-

puts (switches) and outputs (LEDs). Second, the lab

explicitly requires the students to find some additional

software needed and incorporate that into the project. Third, this lab will expose students to the SysTick pe- ripheral and how to use polling to create time delays.
