# 🚐🖧 Raspberry Pi - Arduino Uno CANBUS Transceiver
✅ A guide for setting up and configuring a CANBUS communication system using Raspberry Pi and Arduino Uno.
## ⚙️ Setup and Configuration
### 1️⃣ Enabling the SPI Interface
```sh
sudo raspi-config
```
- **Interface Options** -> **Enable SPI**
- 
### 2️⃣ Updating `config.txt`
```sh
sudo nano /boot/firmware/config.txt
```
Add the following lines at the end of the file:
```sh
dtparam=spi=on
dtoverlay=mcp2515-can0, oscillator=12000000, interrupt=25, spimaxfrequency=20000000
dtoverlay=spi-bcm2835-overlay
```
### 3️⃣ Restarting the System
```sh
sudo reboot
```
### 4️⃣ Installing Required Tools
```sh
sudo apt-get install can-utils
```
### 5️⃣ Restarting the System Again
```sh
sudo reboot
```
### 6️⃣ Enabling the CANBUS Interface
```sh
sudo ip link set can0 up type can bitrate 500000
```
- `ifconfig`
### 7️⃣ Installing the Python CAN Library
```sh
sudo apt update
sudo apt install python3-can
```
### 8️⃣ Running the Python Code
```sh
python3 raspberry-pi-canbus-transmitter.py
```
## 🔄 Setting Up Systemd for Auto-Starting CANBUS
### 1️⃣ Creating the `can0.service` File
```sh
sudo nano /etc/systemd/system/can0.service
```
The content should be as follows:
```ini
[Unit]
Description=CAN0 Interface Up
After=network.target
[Service]
Type=oneshot
ExecStart=/sbin/ip link set can0 up type can bitrate 500000
RemainAfterExit=yes
[Install]
WantedBy=multi-user.target
```
### 2️⃣ Loading and Enabling the Systemd Service
```sh
sudo systemctl daemon-reload
sudo systemctl enable can0.service
sudo systemctl start can0.service
```
### 3️⃣ Final Checks and Restarting
```sh
sudo reboot
```
