EDL LCDs

  • All LCDs are 16bit parallel data
Size / resolution / color Driver
2.4 - 320*240 - 65K ILI9341 <- ILI9325 (New V2.1) <- S6D1121 (Old V1.2)

  • Module the user through the back of the PCB J3 pad set 8/16 bit interface, shorting J3 pad module in 16-bit mode, not less then work in 8-bit mode, module shipments default OPEN, which is shippedThe default is 8-bit interface, 8-bit mode, only 8 (DB8-DB15, DB0-DB7 ground or to unsettled to 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).

EDL

  • 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.
