Pbs:
----
- Synchronization of the two boards:
* Don t care and communicate asyncronously
* Use IR (but crowding and reliability pbs)
- Reliability of IR for datastreaming:
* Send few discrete commands
* work hard on IR protocol (see also crowding)
- IR crowding:
* If both boards send IR signals, possible ambiguity at the receiver side
* If a board both send and receive, how to distinguis self and non
self message.
- Define good features from raw data:
* AAAA
* "good" filters and tresholds
* geometric models
Possible use:
-------------
- IR command:
* define various light patterns
* trigger patterns associated to IR remote commands
- Local rate control:
* get the accel amplitude averaged over axes (AAAA)
* define light patterns based on AAAA range or PWM based on AAAA
Environment control:
--------------------
- Control of music/sound (engine noise modulated by rotation speed)
- Control lightning
- Capture tragectories
photodiode
On IR protocols
---------------
- Digital protocol based on remote codes should be tested to assess reliability speed trade offs. SONY protocol is used to control servo in the IRlib example.
- Analog protocol is never used, is there good reason?
Things to do:
-------------
Define protocol IR
Use flextimer2
calibrate accel
Readings
--------
Protocol for IR remotes
