* 1. Cut the tab off the LCD connector so it can be plugged into the "EXP1" connector the other way. |
|
|
|
* 2. Swap the LCD's +5V (Pin2) and GND (Pin1) wires. (This is the critical part!) |
|
|
|
* 3. Rewire the CLK Signal (LCD Pin9) to LCD Pin7. (LCD Pin9 remains open because this pin is open drain.) |
|
|
|
* 4. A wire is needed to connect the Reset switch at J3 (LCD Pin7) to EXP2 (Pin3) on the board. |
