For now it allows to +to get data from acceleration, gyroscope and electronic compass. + +## General Scheme + +As soon as a client subscribes to the agl-service-iiodevices binding, +the binding gets values from sensors and send it to subscribers as events. +Subscribers can choose their frequency and indicates what values they wants at +subscription. For now, subscribers have also to indicates an uid in order to +create differents events, if arguments differ between clients. ## Verbs | Name | Description | JSON Parameters | -|:-------------------|:-------------------- -----------------------|:--------------------------------------------------------------- | -| subscribe | subscribe to accelero events | *Request:* {"event": "accel"} {"event": "magn"} {"event":anglvel"}| -| unsubscribe | unsubscribe to accelero events | *Request:* {"event": "accel"} {"event": "magn"} {"event":anglvel"}| +|:-------------------|:--------------------------------------------|:--------------------------------------------------------------- | +| subscribe | subscribe to 9 axis events | *Request:* {"event": "accel", "uid": "X", "args":"xy", "frequency": "10" }| +| unsubscribe | unsubscribe to accelero events | *Request:* {"event": "accel", "uid": "X"} | ## Events -There are 3 different events matching with the different sensor available. +For now, there are 3 different events matching with the different available sensors. * "accel": is for acceleration data * "magn": is for gyroscope data -* "anglvel": is for data - -### frequency Event JSON Response - -JSON response has a single field **frequency** which is the currently tuned frequency. - -### station_found Event JSON Response - -JSON response has a single field **value** of the frequency of the discovered radio station. - -# AGL Radio Tuner Binding - -## FM Band Plan Selection - -The FM band plan may be selected by adding: -``` -fmbandplan=X -``` -to the [radio] section in /etc/xdg/AGL.conf, where X is one of the -following strings: - -US = United States / Canada -JP = Japan -EU = European Union -ITU-1 -ITU-2 - -Example: -``` -[radio] -fmbandplan=JP -``` - -## Implementation Specific Confguration - -### USB RTL-SDR adapter - -The scanning sensitivity can be tweaked by adding: -``` -scan_squelch_level=X -``` -to the [radio] section in /etc/xdg/AGL.conf, where X is an integer.
