Picofuse Examples

This repository contains example applications demonstrating the use of the Picofuse library for event-driven embedded hardware programming in Objective-C. You'll need the compiled Picofuse library installed on your system to build these examples, and a compatible compiler toolchain, plus CMake and pkg-config.

Building for Darwin (macOS) or Linux

To build the examples on macOS or Linux, ensure you have the Picofuse library installed (e.g., in /opt/picofuse). If building for macOS, you'll need a gcc compiler toolchain (for example, gcc version 15 installed via Homebrew). Then, you can build the examples using the following command:

TOOLCHAIN_PATH=/opt/homebrew CC=gcc-15 RELEASE=1 make

You can adjust the TOOLCHAIN_PATH and CC variables as needed for your setup. The RELEASE=1 flag builds the examples in release mode; omit it for debug mode. You can also specify the location of the picofuse installation with the PKG_CONFIG_PATH variable if it's not in the default location (/opt/picofuse/lib/pkgconfig). The output binaries will be located in the build/Application directory.

On Linux, any gcc or clang toolchain should work, and you can set the CC variable accordingly.

Building for Pico (Raspberry Pi Pico)

To build the examples for the Raspberry Pi Pico, you'll need to have the Picofuse library compiled for the Pico architecture and a suitable cross-compilation toolchain installed. You can then build the examples using:

TOOLCHAIN_PATH=/opt/LLVM-ET-Arm-19.1.5-Darwin-universal CC=clang RELEASE=1 PICO_BOARD=pico make

You can see which boards are supported by looking at the list of directories in /opt/picofuse/lib/pico. Adjust the TOOLCHAIN_PATH and CC variables as needed for your setup. The output binaries will be located in the build/Application directory, with a .uf2 extension, and you can flash them to your Pico using picotool in the /opt/picofuse/bin directory.
