How to get it up <strong>and</strong> runningConnect the display <strong>and</strong> provide a voltage of 5 up to 20 Volts to the pads Vcc <strong>and</strong> GND.The display should be mounted like shown at the following pictures:1) Place the display on the table infront of you. Now place the module ina way, that module <strong>and</strong> <strong>and</strong> displayconnector will face each other.2) Hold the connector PCB of the displaywith two fingers <strong>and</strong> push theconnector gently to towards the connectoron the main PCB.Always make sure that you will notmistakenly connect the display wrong –it might become destroyed when youpower up the module.3) ReadyThis connector gives you the possibility to remove the display if you want <strong>and</strong> to mount it indistance from the main PCB. Then, the cable should not be too long. 20-30 cm (10 inch)were tested by us <strong>and</strong> should work.If you want to connect or disconnect the display, always switch off power before.We already pre-programmed the controller so you will see a program showing you thestatus of each single port. The ports F4 to F7 show „0“ as they are prepared for the JTAGinterface <strong>and</strong> are not usable otherwise until JTAG is disabled (see last page on details).Programming interfaceYou need a separate ISP-programmer to be able to reprogram this board. This programmeris connected to the D072 board <strong>and</strong> your PC.page 7 Manual D072, ATMega128 board – V1.2© Peter Küsters - www.display3000.com
