casioplot is a preinstalled micropython module on casio graphing calculators that support MicroPython. Such as the Casio fx-CG50

Functions

get_pixel(x, y)

Parameters

  • x : integer, x coordinate on screen
  • y : integer, y coordinate on screen

Returns

  • Returns a tuple with the colour of the specified pixel, if value is off screen it returns None

Gets a pixel on the screen using (x, y) coordinates

Usage

import casioplot

#Valid input

pixel_colour = casioplot.get_pixel(5, 10)
print(pixel_colour)

(255, 255, 255)

#Invalid input

pixel_colour = casioplot.get_pixel(2000, 2000)
print(pixel_colour)

None

set_pixel(x, y, rgb=(0, 0, 0))

Parameters

  • x : integer, x coordinate on screen
  • y : integer, y coordinate on screen
  • rgb : tuple, colour of pixel in RGB format

Returns

  • None

Set a pixel in VRAM using (x, y) coordinates and RGB

Usage

import casioplot

casioplot.set_pixel(20, 20, (255, 0, 0)) #sets the pixel at (20, 20) to red
casioplot.show_screen() #displays VRAM

Set_Pixel_Example

draw_string(x, y, string, rgb=(0, 0, 0), text_size='medium')

Parameters

  • x : integer, x coordinate on screen (starting from upper left corner)
  • y : integer, y coordinate on screen (starting from upper left corner)
  • string : string, string to be displayed on the scrren
  • rgb : tuple, colour of pixel in RGB format
  • text_size : string, size of text, can be small, medium or large

Returns

  • None

Draws a string into VRAM

Usage

import casioplot

casioplot.draw_string(20, 20, "test_string", (255, 0, 0), "large") #draws a large red string starting at (20,20)
casioplot.show_screen() #displays VRAM

Draw_String_Example

show_screen()

Parameters

  • None

Returns

  • None

Displays the VRAM

Usage

import casioplot

casioplot.set_pixel(20, 20, (255, 0, 0)) #sets the pixel at (20, 20) to red
casioplot.show_screen() #displays VRAM

clear_screen()

Parameters

  • None

Returns

  • None

Clears the VRAM

Usage

import casioplot

casioplot.set_pixel(20, 20, (255, 0, 0)) #sets the pixel at (20, 20) to red
casioplot.show_screen() #displays VRAM
casioplot.clear_screen() #clears VRAM
casioplot.set_pixel(20, 30, (0, 255, 0)) #sets the pixel at (20,30) to green
