| − | ===Zigbee===
| + | |
| − | A zigbee solution is foreseen for the wireless communication.<br>
| + | |
| − | A presentation concerning Zigbee can be found here: [http://www.armadeus.com/downloads/assos/zigbee_slides.pdf].<br>
| + | |
| − | This has to be evaluated.<br>
| + | |
| − | In order to be able to benefit from the complete Zigbee services, two Microchip ICs will be used (PIC18Fxx and the MRF) as the Zigbee stack is provided for free [http://www.armadeus.com/downloads/assos/domos_zigbee_stack.pdf].<br>

| − | | + | |
| − | <strong>Next steps:</strong>
| + | |
| − | * 2 zigbee prototype boards with a PIC and the MRF. One will be used for the endpoint and the other will be connected to the APF through the RS232 (TTL) interface. | + | |
| − | * Specification of the communication protocol between the APF and the endpoint (datagram based ?). Evalution of the actual solutions.
| + | |
| − | * Developpment of a small application on the APF side to communicate with the zigbee board by using the communication protocol previously defined.
| + | |
| − | * test of the Zigbee stack provided by Microchip. A simple program has to be written. Default Microchip environment has to be used.
| + | |
| − | | + | |
| − | ===RS485===
| + | |
| − | Wirelless communication is the best way to connect Endpoints and controler. But sometimes wired connexion will be need for direct or faster access. We could considerate RS485 connexion.
| + | |
| − | With RS485 nom we can connect up to 32 controllers on one bus.
| + | |
| − | | + | |
| − | <strong>Next steps:</strong>
| + | |
| − | * APF with RS485 transceiver with a PIC and the same transceiver.
| + | |
| − | * Needs to connect APF to a RS485 bus : Linux driver developement? UART driver ?
| + | |
| − | * Schematics for connecting a pic to RS485 bus
| + | |
| − | * Specification of the communication protocol between APF and endpoint. Application protocol can be share with Zigbee high level protocol or, must we developped new protocol ?
| + | |
| − | * Developpment of a small application on the APF and on the PIC to test communication.
| + | |
| − | | + | |
| − | ===Endpoint prototype board===
| + | |
| − | In order to develop and test endpoint protocols, a prototype board is under-developement. This board must allow connections between boards, PC to proto-board and APF to proto-board.
| + | |
