R1BBIT · EMBEDDED LANGUAGE

R1BBIT Script

A compact, BASIC-style language purpose-built for IoT. Control hardware, draw graphics, read sensors, and build interactive UI — in a few lines of code.

Full Documentation Quick Start

Why R1BBIT Script

Built around a single idea: make embedded programming feel effortless.

⚡

Instant to learn

BASIC-inspired syntax. If you've ever written a few lines of code, you're already productive.

🔌

Hardware-first

Built-in commands for ADC, PWM, DAC, I2C, RTC, WS2812 — no libraries, no boilerplate.

🎨

Graphics engine

Native support for ST7735, ILI9341, ILI9488, ST7796, ST7789, SSD1306 with shapes, text, bitmaps and sprites.

📡

Sensor ready

DHT, BMP280, SHT21, CCS811, VL53L0X, HX711, DS18B20, MAX30102 — all one-liners.

🎛️

Interactive widgets

Buttons, sliders, gauges, graphs and progress bars with real-time variable binding and touch.

☁️

Cloud by default

Push variables to R1BBIT Cloud over Wi-Fi with a single call. Dashboards from your phone, anywhere.

🧠

Signal processing

128-bin FFT at 16 kHz with asymmetric EMA smoothing — responsive spectrum visualizations out of the box.

🧩

2D arrays & matrices

32 KB memory pool, range-based init, linear addressing, copy operations — real data structures, not toys.

See it in action

A few snippets that show the language's character.

VAR A, B, C               // variable declaration
A = 10                    // assignment
B = A * 2 + 5             // arithmetic: + - * / %

IF A > 5 THEN             // conditions: = == <> < > <= >= AND OR
    C = 1
ELSE
    C = 0
ENDIF

FOR I = 0 TO 9 STEP 1     // FOR / NEXT loop
    PRINT I
NEXT

WHILE A < 100             // WHILE / WEND loop
    A = A + 1
WEND

PAUSE 1000                // delay in milliseconds
PRINT A.h                 // formatted output (.h hex, .b binary, .Nz zero-pad)

DISPLAY_INIT ILI9341, SPI, ROT_0

VAR COLOR
COLOR = RGB565(255, 140, 0)          // orange

DISPLAY_CLEAR RGB565(0, 0, 0)
DISPLAY_RECT_FILL 10, 10, 220, 60, COLOR
DISPLAY_TEXT 20, 25, "HELLO R1BBIT", 2, COLOR
DISPLAY_CIRCLE 120, 160, 40, RGB565(0, 200, 255)

VAR POLY[6] = {50,200, 120,260, 190,200, 50,200}
DISPLAY_POLYGON POLY, RGB565(100, 255, 100)

VAR TEMP, HUM

BMP280_INIT
DHT_INIT PIN_5

WHILE 1
    DHT_READ TEMP, HUM               // temperature + humidity
    PRINT "T=", TEMP, "  H=", HUM

    VARS_SEND(TEMP, HUM)             // push to R1BBIT Cloud over Wi-Fi
    PAUSE 5000
WEND

VAR VOLUME = 50

SLIDER_INIT 20, 100, 200, 30, 0, 100, VOLUME
GAUGE_INIT 160, 200, 60, 0, 100, VOLUME, "VOLUME"
BUTTON_INIT 20, 260, 100, 40, "MUTE", TOGGLE, ON_MUTE

WHILE 1
    PAUSE 20                         // widgets update automatically
WEND

ON_MUTE:
    VOLUME = 0
RETURN

Under the hood

Everything that ships with the interpreter.
