3.4 Uploading the Controller Component

The controller software must be uploaded to the micro-controller board. To do this, connect the micro-controller (normally via its USB port) to your PC and type ‘make flash’. With some systems it is necessary to wait a few seconds between connecting the controller and issuing the command.

The exact response that you will see on the screen is dependent upon the micro-controller however it should finish with something like this:
