At this stage in the project, we have created the basic drivers that will control all the low-level hardware devices in our project. We have drivers that allow us to generate PWM signals to drive RGB LEDs and a driver to access the I/O expander chip to write and read its status. At this point, we would normally develop a test harness that could fully test the drivers. This would allow us to discover issues we might have with functionality or boundary conditions. Since developing a test harness is an entire project in itself, we will save the test harness discussion for the next chapter. For now, we will jump ahead and create a test application that meets our project requirements and develop a few simple test cases to make sure that the high-level system meets those requirements.
