Learn TINYGO with Real Code Examples

TinyGo allows Go developers to target microcontrollers and embedded devices.

Supports compiling Go code to WebAssembly for browser and server applications.

Optimized for small binary size and low memory usage.

Facilitates rapid development for IoT and embedded systems using familiar Go syntax.

Integrates with Arduino, Raspberry Pi, and other small boards for direct hardware control.

TinyGo compiler for Go code targeting embedded systems

Hardware-specific packages for GPIO, I2C, SPI, PWM, UART

Support for Go slices, maps, structs, interfaces (subset)

Cross-platform compilation for ARM, AVR, RISC-V, WebAssembly

Integration with standard Go tooling where compatible

Go syntax - used for writing TinyGo programs

Microcontroller board - target hardware for code

Peripherals - GPIO, I2C, SPI, PWM, UART components

WebAssembly - target format for web applications

Package - collection of Go code, often hardware-specific

Main Go source files (.go)

Hardware-specific packages (GPIO, I2C, SPI, etc.)

TinyGo configuration (target flags, options)

Optional WebAssembly build directory for WASM output

Documentation and README for project setup

Write Go code using supported TinyGo features

Import necessary hardware or standard packages

Compile code with TinyGo for target architecture

Flash or deploy compiled binary to the device

Test, debug, and iterate based on results

Beginner: simple LED blink programs

Intermediate: reading sensors and controlling actuators

Advanced: multiple peripherals and concurrent goroutines

Expert: WebAssembly applications interacting with hardware

Architect: full IoT systems with network, sensors, and cloud integration

TinyGo vs Go - TinyGo subset for microcontrollers and WASM

TinyGo vs Arduino C/C++ - easier Go syntax, smaller ecosystem

TinyGo vs CircuitPython - faster, compiled, Go concurrency support

TinyGo vs Rust embedded - Go easier for beginners, Rust more memory-safe

TinyGo vs standard Go - TinyGo optimized for constrained environments
