CircuitMess Wheelson

The repository for the core firmware that comes preloaded on every Wheelson.

Autonomous cars are the future and we’ll show you how it works.

This tiny wheeled robot has a camera and a microcomputer and can be programmed to autonomously navigate a small road while driving, just like an autonomous car would.

CircuitMess Wheelson is also a part of CircuitMess STEM Box - a series of fun electronic kits to help children and adults understand the basics of technologies everybody's talking about.

src/Apps contains different apps selectable in the main menu. To add a new entry to the menu, add it in the MainMenu constructor.

Buttons and other board-specific defines should be in src/Wheelson.h

Compiling

The firmware is based on the Wheelson Library. It is, along other required libraries, automatically installed when you install the CircuitMess ESP32 Arduino platform. More info on CircuitMess/Arduino-Packages.

Using Arduino IDE

Simply open Wheelson-Firmware.ino using Arduino IDE, set the board to Wheelson, and compile.

Using CMake

To compile and upload you need to have CMake and arduino-cli installed. You also need to have both of them registered in the PATH.

In the CMakeLists.txt file change the port to your desired COM port (default is /dev/ttyUSB0):

set(PORT /dev/ttyUSB0)

Then in the root directory of the repository type:

mkdir cmake
cd cmake
cmake ..
cmake --build . --target CMBuild

This will compile the binaries, and place the .bin and .elf files in the build/ directory located in the root of the repository.

To compile the binary, and upload it according to the port set in CMakeLists.txt, run

cmake --build . --target CMBuild

in the cmake directory.

To make effective use of the makefile, edit the ACLI and PORT variables accordingly. ACLI should point to the arduino-cli executable, and PORT is the board COM port.

Three targets are defined:

• build (default target) - builds the firmware in the build/ directory
• upload - builds if necessary and uploads to the board
• clean - removes the build/ directory

Usage (in the directory where the Makefile is):

make <target>

Will probably add PlatformIO support if the need arises. Hit us up with an issue if you'd like us to add a platformio config.
