- | RS485 will be used as the principal bus. | ||

- | ==== Software ==== | ||
- | |||
- | In order to communicate between the nodes, the MODBUS RTU protocol will probably be used. | ||
- | |||
- | === Addressing === | ||
- | |||
- | If possible, the addresses could be dinamically addressed using some discovery protocol. | ||
- | This seems really to realize on modbus and thus, some DIP switch could allow the user to set nodes addresses. | ||
- | Since the modbus adressing can go up to 255, a 8 input DIP switch will use 8 GPIOs. |
