Control onboard led RGB esp32s3 with micros-ROS and ROS2 environment

## Prerequisites 

- Install [ROS2 Humble](https://docs.ros.org/en/humble/index.html)

## Install

```bash

sudo apt install python3-vcstool python3-colcon-common-extensions git wget

```

#### 1. Create a workspace folder

```bash

mkdir -p ~/uros_ws

```

#### 2. Install micro-ROS-AGENT

```bash

cd ~/uros_ws

git clone -b humble --recursive https://github.com/micro-ROS/micro-ROS-Agent.git

rosdep install --rosdistro $ROS_DISTRO --from-paths micro-ROS-AGENT -i -r -y

cd ~/uros_ws/micro-ROS-AGENT

colcon build --symlink-install --cmake-args -DCMAKE_BUILD_TYPE=Release

```

#### 3. Clone repository

```bash

cd ~/uros_ws

git clone --recursive https://github.com/moralessP/micro-ROS-esp32s3-led-RGB.git

cd ~/uros_ws/micros-ROS-esp32s3-led-RGB

```

Set IP address and communication port (8888). Also SSID and password 

```bash

idf.py set-target esp32s3

idf.py menuconfig

idf.py build   

```

#### 4. Run

Flash firmware

```bash

idf.py -p PORT flash

```

Open a terminal  

```bash

source ~/uros_ws/micro-ROS-AGENT/install/setup.bash

ros2 run micro_ros_agent micro_ros_agent udp4 --port 8888

```

#### 5. Usage 

Open a new terminal  

```bash

ros2 topic pub --once /led_rgb std_msgs/msg/UInt8MultiArray "{data: [255, 255, 255]}" # send R=255 G=255 B=255 to led_rgb topic 

```
