AiP31068L (LCD ) Slave Address : 0X7C. PCA9633DP2 (RGB) Slave Address: 0XC0. 9. FUNCTION SPECIFICATIONS 9.1. Basic Setting To drive the LCD module corretly and provide normally display, please use the following setting: 一 N=1, 2-line display 一 F=0, 5×8 dots font 一 D=1, display on Note: 一 These setting/commands should issue to the LCD module while start up. 一 See the Display Commands section for details. 9.2.
一 一 一 一 一 一 一 NOTE: 一 DL=1, 8-bit interface F=0, 5×8 dot character font D=0, Display off C=0, Cursor off B=0, Blinking off I/D=1, Increment by 1 S=0, No shift Reset routine could not generate the Basic Setting 9.3. Display Memory Map There are two main memory-areas in the LCD module for display. 一 Character Generator RAM(CGRAM) 一 Display Data RAM(DDRAM) 9.3.1. Character Generator RAM(CGRAM) Character Generator RAM is for storing the User-defined Characters(5×8 dots font).
9.3.2. Character code ROM Please refer to AiP31068L datasheet. http：//www.DFRobot.
.4. Display Commands NOTE: 一 Do not use any other commands not listed, or the system malfunction may result. 一 For the details of rte display commands, please refer to AiP31068L datasheet. 10.DESIGN AND HANDING PRECAUTION 10.1. The LCD panel is made by glass. Any mechanical shock (eg. Dropping form high place) will damage the LCD module.Do not add excessive force on the surface of the display, which may cause the Display color change abnormally. 10.2. The polarizer on the LCD is easily get scratched.
.5. When mounting the LCD module, make sure that it is free form twisting, warping and distortion. 10.6. Ensure to provide enough space(with cushion) between case and LCD panel to prevent external force adding on it, or it may cause damage to the LCD or degrade the display result 10.7. Only hold the LCD module by its side. Never hold LCD module by add force on the heat seal or TAB. 10.8. Never add force to component of the LCD module. It may cause invisible damage or degrade of the reliability. 10.9.
