Developing Lift Monitoring and Snow-Making Control for the MediaEngine
This section details the MediaEngine interface hardware design. After the engineers find space in the memory map for the I/O circuit, they configure the CPU registers and test the circuit by using the helloworldbit program. They then develop the MediaEngine liftmon_snowcon device driver, which enables the MediaEngine target board to monitor lifts and control snow-making equipment.
Designing the External Interface Hardware for the MediaEngine
In order for the MediaEngine to monitor lifts and control snow making, it needs to read six inputs and control four outputs. In this design, an output latch and an input buffer connect directly to the MediaEngine's CPU bus. The MediaEngine ...
