 1 | # CanHacker (lawicel) CAN adapter on Arduino + MCP2515
 2 | 
 3 | Testes with Arduino Nano.
 4 | On Arduino Uno have problem with too long boot period and losing first command when work with CanHacker application
 5 | 
 6 | ## Installation
 7 | 
 8 | 1. Install [MCP2515 Library](https://github.com/autowp/arduino-mcp2515)
 9 | 2. Install [CanHacker Library](https://github.com/autowp/arduino-canhacker)
10 | 3. Configure sketch: MCP2515 CS pin, SoftwareSerial pins if required, change baudrates
11 | 4. Use with [CanHacker](http://www.mictronics.de/projects/usb-can-bus/) or CANreader (soon)
