With the PCB placed to the right side of the screen, connect the other side of
the ribbon cable to HRD2 on the PCB, ensuring the bump on the ribbon cable
connector aligns with the HRD2 label on the PCB. Ensure all the connector
wholes are properly aligned with all the connector pins. The red side of the
ribbon cable should be closest to the prototyping area.
E)
You’re now ready to power the screen up for testing! Although the buttons
are not yet attached for setting the time or switching the animations, once you
plug the power supply into the board and plug the supply into the wall, the display
should show a simple time animation with hours and minutes. The DOTKLOK
may take a few seconds to start up, this is normal.
A note about the power
supply: only use a 5V supply as included with your kit, input voltages greater than
5V WILL DAMAGE the board!
