About

What is emgo?

Emgo is an open-source project that provides a compiler and a set of packages for running Go programs on small 32-bit microcontrollers. It functions by generating C as an intermediate code, which is then compiled by a C compiler to produce loadable binaries. While the main development has shifted to Embedded Go for higher hardware compatibility, Emgo remains valuable for smaller MCUs. It supports ARM Cortex-M based MCUs and requires the Go compiler and ARM embedded toolchain for setup. The project includes examples and helper scripts for building, loading, and debugging programs on development boards like STM32 Nucleo.

Best used for

Ideal for developers who need to program small 32-bit microcontrollers using the Go language, compile Go code for embedded systems, and debug bare-metal applications. Especially valuable for those working with ARM Cortex-M based MCUs and seeking an open-source solution.

FAQs

What kind of microcontrollers does Emgo support?

Emgo primarily supports ARM Cortex-M based microcontrollers. To build code for these architectures, you will need to install an ARM embedded toolchain, such as the GNU ARM Embedded Toolchain, and configure the necessary environment variables.

How does Emgo compile Go programs for embedded systems?

Emgo uses a two-step compilation process. It first compiles Go code into C as an intermediate language. Then, it utilizes a standard C compiler to produce the final loadable binaries suitable for the target microcontroller.

Are there examples available to help me get started with Emgo?

Yes, Emgo includes example directories for various microcontrollers, such as STM32 and nRF5. These examples come with build and debug scripts to simplify the process of compiling, loading, and debugging your programs on development boards.
