Introduction
evive library for TFT Screen in Arduino IDE includes certain functions that allows you to draw lines and different shapes such as:
- Rectangle
- Circle
- Triangle
Functions
Below is the list of the functions present in the library:
| Function | Description |
|---|---|
| drawLine(int16_t x0, int16_t y0, int16_t x1, int16_t y1, uint16_t color) | Draw a line using two points |
| drawFastVLine(int16_t x, int16_t y, int16_t h, uint16_t color) | Draw a vertical line |
| drawFastHLine(int16_t x, int16_t y, int16_t w, uint16_t color) | Draw a horizontal line |
| drawRect(int16_t x, int16_t y, int16_t w, int16_t h, uint16_t color) | Draw a rectangle using one point coordinate, width and height |
| fillRect(int16_t x, int16_t y, int16_t w, int16_t h, uint16_t color) | Draw a filled rectangle using one point coordinate, width and height |
| drawCircle(int16_t x0, int16_t y0, int16_t r, uint16_t color) | Draw a circle using center point coordinate and radius of the circle |
| fillCircle(int16_t x0, int16_t y0, int16_t r, uint16_t color) | Draw a filled circle using center point coordinate and radius of the circle |
| drawTriangle(int16_t x0, int16_t y0, int16_t x1, int16_t y1, int16_t x2, int16_t y2, uint16_t color) | Draw a triangle using three points coordinate |
| fillTriangle(int16_t x0, int16_t y0, int16_t x1, int16_t y1, int16_t x2, int16_t y2, uint16_t color) | Draw a filled triangle using three points coordinate |
| drawRoundRect(int16_t x0, int16_t y0, int16_t w, int16_t h, int16_t radius, uint16_t color) | Draw a round rectangle using one point coordinate, width, height and radius |
| fillRoundRect(int16_t x0, int16_t y0, int16_t w, int16_t h, int16_t radius, uint16_t color) | Draw a filled round rectangle using one point coordinate, width, height and radius |
