  1. Advanced Software Writing Lab 5 Introduction This material exempt per Department of Commerce license exception TSU

  2. Introduction • This lab guides you through the process of writing an Interrupt Service Routine that utilizes timers and an interrupt controller. • You will add a timer and interrupt controller and connect them up to the system • You will assign an interrupt handler in the Software Platform Settings • You will also develop an interrupt handler routine in the Software Developer’s Kit (SDK), and generate the executable • You will create a new Software Project in XPS that points to the executable • You will update the bitstream • You will download and test operation on the XUP board

  3. Objectives After completing this module, you will be able to: • Utilize the OPB timer • Assign an interrupt handler to the OPB timer • Develop an interrupt handler function
