1.4 Setup for Testing

Before setting up the application, it is best to test out the display. This is easily done with a PC.

The following is a list of requirements for testing;

5. Windows will give a prompt for drivers for a USB ⇔ Serial Device.

6. Select “Specify location”, and navigate to the directory the ﬁle was uncompressed to.
