E-Ink
Before using the E-Ink screen operation function, you need to create an instance and pass in the screen driver address. Call M5.M5Ink.isInit() and initialize with M5.M5Ink.clear();.
#include "M5CoreInk.h"
Ink_Sprite InkPageSprite(&M5.M5Ink);
void setup()
{
M5.begin();
digitalWrite(LED_EXT_PIN,LOW);
if( !M5.M5Ink.isInit())
{
Serial.printf("Ink Init faild");
while (1) delay(100);
}
M5.M5Ink.clear();
}
creatSprite
Syntax:
int creatSprite(uint16_t posX, uint16_t posY, uint16_t width = 200, uint16_t height = 200, bool copyFromMem = true);
Description: create image area, configure whether to get image data buff from screen driver (default is to save true).
The x coordinate of the >create image area must be an integer multiple of 8. (eg: 0 , 8 , 16...) Otherwise, the display will not work properly.
Example:
if( InkPageSprite.creatSprite(0,0,200,200,true) != 0 )
{
Serial.printf"Ink Sprite creat faild");
}
Serial.printf("Ink Sprite creat successful");
clear
Syntax:
void clear( int cleanFlag = CLEAR_DRAWBUFF );
Description: Clear the content of the image area, CLEAR_DRAWBUFF (clear the image data that has not yet been pushed) CLEAR_LASTBUFF (clear the cache area of the image data refreshed last time, and refresh the screen completely when it is pushed again)
Example:
InkPageSprite.clear();
deleteSprite
Syntax:
int deleteSprite();
Description: Release the created image area
Example:
InkPageSprite.deleteSprite();
pushSprite
Syntax:
int pushSprite();
Description: Push the edited image data to the image area (after using the drawing API to operate, you need to push to refresh the screen)
Example:
InkPageSprite.drawString(10,50,"Hello World!",&AsciiFont8x16);
InkPageSprite.pushSprite();
drawPix
Syntax:
void drawPix(uint16_t posX,uint16_t posY,uint8_t pixBit);
Description: draw a single pixel(the parameter pixBit is black when 0 is passed in, and white when 1 is passed in)
Example:
InkPageSprite.drawPix(100,100,0);
InkPageSprite.pushSprite();
FillRect
Syntax:
void FillRect(uint16_t posX, uint16_t posY, uint16_t width, uint16_t height, uint8_t pixBit);
Description: draw a rectangle (the parameter pixBit is black when 0 is passed in, and white when 1 is passed in)
Example:
InkPageSprite.FillRect(0,0,100,100,0);
InkPageSprite.pushSprite();
drawFullBuff
Syntax:
void drawFullBuff(uint8_t* buff, bool bitMode = true);
void drawBuff(uint16_t posX, uint16_t posY, uint16_t width, uint16_t height, uint8_t* imageDataptr);
Description: To draw the entire page, you need to pass in the complete page Buff
drawChar
Syntax:
void drawChar(uint16_t posX,uint16_t posY,char charData,Ink_eSPI_font_t* fontPtr);
Description: draw characters
Example:
InkPageSprite.drawChar(35,50,'M');
InkPageSprite.pushSprite();
drawString
Syntax:
void drawString(uint16_t posX,uint16_t posY,const char* charData,Ink_eSPI_font_t* fontPtr = &AsciiFont8x16);
Description: draw string
Example:
InkPageSprite.drawString(35,50,"Hello World!");
InkPageSprite.pushSprite();
getSpritePtr
Syntax:
Description: Get image buff data
uint8_t* getSpritePtr(){ return _spriteBuff;}
Description: Get image width coordinate data
uint16_t width(){ return _width;}
Description: Get image height coordinate data
uint16_t height(){ return _height;}
Description: Get image X coordinate data
uint16_t posX(){ return _posX;}
Description: Get Y coordinate data of image area
uint16_t posY(){ return _posY;}
