LCDWIKI KBV lib Manual 1.Introduction The LCDWIKI KBV lib is the hardware level lib of the lcd modules with parallel port,it need be paired with the GUI lib for each display modules. The LCDWIKI KBV lib have the derived class from LCDWIKI GUI lib.if you want to call functions of LCDWIKI GUI lib,you only need to use the LCDWIKI KBV class and you have to do this. The LCDWIKI KBV lib support 8bits and 16bits display.you can open the file of lcd_mode.h to modify. 2.FUNCTIONS DECLARATION definiens LCDWIKI_KBV(uint16_t model,uint8_t cs, uint8_t cd, uint8_t wr, uint8_t rd, uint8_t reset) function The main class constructor when using 8bit or 16bit display modules parameters model : the model of display modules cs : the chip selection pin in Development board cd : the command/data pin in Development board wr : the write control pin in Development board rd : the read control pin in Development board reset : the reset pin in Development board returned value notes None if modules is unreadable or you don't know the width and height of modules,you can use this constructor definiens LCDWIKI_KBV(int16_t wid,int16_t heg,uint8_t cs, uint8_t cd, uint8_t wr, uint8_t rd, uint8_t reset) function The main class constructor when using 8bit or 16bit display modules parameters wid : the width of display modules heg : the height of display modules cs : the chip selection pin in Development board cd : the command/data pin in Development board wr : the write control pin in Development board rd : the read control pin in Development board reset : the reset pin in Development board returned value None notes if modules is readable or you know the width and height of modules,you can use this constructor definiens function void Init_LCD(void) Initialize the LCD modules parameters None returned value None notes None definiens function void reset(void) Reset the LCD modules parameters None returned value None notes None definiens function parameters void

function parameters void init_table8(const void *table, int16_t size) Write a series of 8bit command and data to the lcd modules table : the array of command and data to point size : the size of the array of command and data returned value None notes None definiens function parameters void init_table16(const void *table, int16_t size) Write a series of 16bit command and data to the lcd modules table : the array of command and data to point size : the size of the array of command and data returned value None notes None definiens function void Push_Command(uint16_t cmd, uint8_t *block, int8_t N) Set a command and a series of 8bit data to the lcd modules at a time parameters cmd : the 16bits command value block : the array of 8bit data to point N : the size of the array of 8bit data returned value None notes None definiens function parameters uint16_t Color_To_565(uint8_t r, uint8_t g, uint8_t b) Pass three 8bits colour value and get the 16bits colour value r : the 8bits red
