/* Telemetry uses four tasks. Two are created for the main telemetry
* stream called "TelTx" and "TelRx". Two are created to handle the OPLink
* radio connection, called "RadioTx" and "RadioRx", the latter being
* overridden by USB if connected.
*
* The following code uses a "local" prefix to refer to the telemetry channel
* associated with a port on the FC and a "radio" prefix to refer to the
* telemetry channel associated with the OPLink/USB.
*
* The "local" telemetry port to use is defined by PIOS_COM_TELEM_RF in
* PIOS_Board_Init().
*
* A UAVTalk connection instance, telemUavTalkCon, is associated with the
* "local" channel and another, radioUavTalkCon, with the "radio" channel.
* Associated with each instance is a transmit routine which will send data
* to the appropriate port.
*
* Data is passed on the telemetry channels using queues. If
* PIOS_TELEM_PRIORITY_QUEUE is defined then two queues are created, one normal
* priority and the other high priority.
*
* The "Tx" tasks read events first from the priority queue and then from
* the normal queue, passing each event to processObjEvent() which ultimately
* passes each event to the UAVTalk library which results in the appropriate
* transmit routine being called to send the data back to the recipient on
* the "local" or "radio" link.
