The micropython sdk contains two main modules - modules.display and modules.input. Import them at the top of your file with:
import modules.display as display
import modules.input as inputDisplay
General shape
To make changes to the display, call the following functions to update the frame buffer in RAM. Then call display.update() to send the data to the screen.
All colours are in RGB565 format.
display.pixel
Arguments: x, y, colour.
Draws a single pixel to the screen
display.rect
Arguments: x, y (top left corner), width, height, colour.
Draws a rectangle to the screen
display.text
Arguments: text, x, y, colour
Draws text to the screen at top left coords of x and y. A single character is size 8x8.
display.draw_image
Arguments: image_name, x, y, image_width, image_height
Draws an image stored in /img in the device’s flash to the screen. As of now, the logic cannot infer the image width and height, so you must explicitly pass them. This my change in future.
When you upload an image from the web editor, it is automatically placed in this directory.
display.update
No arguments.
Flushes data to the display.
Input
The input module deals with button presses.
General shape
Call input.update to check all the buttons, and update state (this includes moving the store of current button presses to last button presses). Call this before you do any input handling in your main game loop
Key names are strings, and are “A”, “B”, “UP”, “DOWN”, “LEFT” and “RIGHT”
input.is_pressed
Argument: key name
Returns a boolean on whether it is currently pressed
input.was_just_pressed
Argument: key name
Returns true if the key is pressed this frame but was not last frame.
input.was_just_released
Argument: key name
Returns true if the key was pressed last frame but was not this frame.
