connect). 8-bit interface occupied IO than 16 interface occupied IO to 8 less, but more slowly, 16-bit interface occupied IO 8 more, but faster).

Pins Definition and Wiring

EDL

EDL 2.4 pins EDL 3.2 pins

◾ Extra VCC, GND, LEDA (LED back light) also need to connect
◾ LED_A Pins for the back light of the screen, max volt at 3.2V, connect 20ohm for 3.3V, and 500ohm for 5V, as a current limited purpose.

◾ All the pins must be connected, if not connect, it won't work (Athough not all the pins are defined in the arduino sketch).
◾ All the pins power/logic should be 3.3V, include LCD back light.
◾ LCD power supply can be 5V, on board LDO regulator
◾ 1.8 can use 5V for test, the rest can not do
