ZaurParser

ZaurParser is a simple script parser for Arduino UNO R4 WiFi with support for a Waveshare 2.8" TFT touchscreen (recommended, but any other ST7789-compatible display can be used) and SD card. It allows you to execute graphical commands, handle variables, perform conditional jumps, and display BMP images.

Features

• Display text and graphics on the TFT screen
• Touch and variable support
• Conditional jumps (jump, jumpif)
• Loading and displaying BMP images from SD card
• Simple color support (names and RGB565)

Requirements

• Arduino UNO R4 WiFi or Minima
• 2.8" TFT screen (Waveshare) compatible with Arduino_GFX
• SD card reader
• Libraries: Arduino_GFX_Library, XPT2046_Touchscreen, SD

Getting Started

1. Upload the code to your Arduino.
2. Place the main.zs file on the SD card.
3. On startup, the parser will automatically execute commands from the file.
4. All done! Create your own scripts and OS!

Example main.zs file

echo "Start!"
disp.fill "white"
disp.textcolor "red"
disp.textsize "2"
disp.cursor "10,10"
disp.print "Touch the screen!"
disp.drawrect "20,60,200,100,blue"
os.delay "2000"
disp.textcolor "green"
disp.cursor "10,120"
disp.print "X=$touch_x Y=$touch_y Z=$touch_z"
disp.cursor "10,150"
disp.print "Touch: $touch_detected"
disp.render "/images/logo.bmp"
os.delay "3000"
echo "End!"
