Instant coding
Write and run BASIC programs straight from the serial terminal. No compile loop — just type and execute.
BASIC IS BACK ON BOARD
A BASIC interpreter firmware for ESP32.
No compiler. No IDE. No complicated setup.
Flash Basic32, open a serial terminal, and start coding like in the 80s — on real ESP32 hardware with modern connectivity.
Open the left menu to install Basic32, access tools, and download resources.
10 PRINT "HELLO BASIC32"
20 GOTO 10
RUNSupport Basic32
If you enjoy using Basic32 and want to support development, you can buy me a coffee ☕
Your support helps keep the project alive and growing.
What it can do
Storage & files
Save and load your code on SPIFFS or SD card. List, rename, delete files and keep projects organized.
Hardware control
Digital/analog I/O, PWM, servos, sensors: a friendly BASIC layer to prototype faster.
Graphics
Draw shapes and text with Adafruit GFX style commands. OLED, TFT, LCD — even touch panels.
Networking
Wi-Fi, HTTP, MQTT, ESP-NOW and nRF24 to connect projects and share data wirelessly.
Retro workflow
The “home computer” feeling — but on real hardware you can plug into LEDs, displays and sensors.
