Function Specifications 3.1 Adjusting the Display Contrast A Variable-Resistor must be connected to the LCD module for providing a reference to V0. Adjusting the VR will result the change of LCD display contrast. The recommended value of VR is 25k to 50k 3.2 Resetting the LCD module The LCD module should be initialized by using /RST terminal. While turning on the VDD and VSS power supply, maintain /RST terminal at LOW level. After the power supply stabilized, release the reset terminal (/RST=HIGH) 3.3 Display Pixel Map 1,1 (D7) 2,1 (D6) 3,1 (D5) 4,1 (D4) 5,1 (D3) - - - - - - 156,1 (D4) 157,1 (D3) 158,1 (D2) 159,1 (D1) 160,1 (D0) 1,2 (D7) 2,2 (D6) 3,2 (D5) 4,2 (D4) 5,2 (D3) - - - - - - 156,2 (D4) 157,2 (D3) 158,2 (D2) 159,2 (D1) 160,2 (D0) 1,3 (D7) 2,3 (D6) 3,3 (D5) 4,3 (D4) 5,3 (D3) - - - - - - 156,3 (D4) 157,3 (D3) 158,3 (D2) 159,3 (D1) 160,3 (D0) : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : 1,78 (D7) 2,78 (D6) 3,78 (D5) 4,78 (D4) 5,78 (D3) - - - - - - 156,78 (D4) 157,78 (D3) 158,78 (D2) 159,78 (D1) 160,78 (D0) 1,79 (D7) 2,79 (D6) 3,79 (D5) 4,79 (D4) 5,79 (D3) - - - - - - 156,79 (D4) 157,79 (D3) 158,79 (D2) 159,79 (D1) 160,79 (D0) 1,80 (D7) 2,80 (D6) 3,80 (D5) 4,80 (D4) 5,80 (D3) - - - - - - 156,80 (D4) 157,80 (D3) 158,80 (D2) 159,80 (D1) 160,80 (D0) Pixel mapping (Top View) Based on the top view of the LCD module, the 1, 1 (x, y) pixel is the upper-left pixel; the 160, 80 (x, y) pixel is the lower-right pixel. Note: *1. For the details of memory mapping please refer to RA8803 datasheet. LCD module VDD V0 VOUT |
