I’m using a Raspberry Pi 3 as the CPU in custom burn-in carts for cycling our Android tablets. It is hard to beat the 7” touch display using a Flask front end for quick development. The carts often have power connected and disconnected when moved around. We are also using a network inside of the carts for talking with tablets under test and need to bring this up each time we move carts and cycle power.
Before I get to deeply into specific functionality and operation of our charging carts, I thought it would be good to take a detour into drivers for custom hardware. In addition I’ll cover mocking hardware devices to allow testing of your drivers and operating your system in a simulation with no hardware present. This allows you to flush out your hardware design with software before fabricating PCBs. (A PCB takes a long time to “compile”.
