Dispcolor Component

Common LCD functions

Add as submodule:

git submodule add https://github.com/liyanboy74/dispcolor.git components/dispcolor

Select LCD Type:

Edit #define DISPCOLOR_type in dispcolor.h file , or Define DISPCOLOR_type=1 or 2 or ...

Adapt to ESP-IDF

Example for GC9a01 LCD:

Clone GC9A01 Component

Edit CMakeLists.txt file and edit patch of header gc9a01.h as below example:

set(LCD_Header_Dir "../gc9a01")

Example Test:

#include <stdio.h>
#include <string.h>
#include "freertos/FreeRTOS.h"
#include "freertos/task.h"
#include "driver/gpio.h"
#include "sdkconfig.h"

#include "dispcolor.h"

#define STACK_SIZE              2048

void LCD(void * arg)
{
    dispcolor_Init(240,240);

    dispcolor_FillCircleWu(120,120,100,YELLOW);
    dispcolor_Update();

    for(;;)
    {
    }
}

void app_main(void)
{
    TaskHandle_t LCDHandle;

    xTaskCreate(LCD,"Test LCD",STACK_SIZE,NULL,tskIDLE_PRIORITY,&LCDHandle);
    configASSERT(LCDHandle);
}

Simulate LCD

Clone SIMLCD Component

Edit CMakeLists.txt file and edit patch of header simlcd.h as below example:

set(LCD_Header_Dir "../simlcd")

Adapt to other LCD

You may need to edit the following functions :

void dispcolor_Init(uint16_t Width, uint16_t Height);
void dispcolor_Update();
void dispcolor_DrawPixel(int16_t x, int16_t y, uint16_t color);
void dispcolor_FillRect(int16_t x, int16_t y, int16_t w, int16_t h,uint16_t color);
