If the payload uses a PSAS CAN node, then most of the software is handled for you. The data from the CAN node will automatically be logged on the FC and can be sent down the telemetry channel if you want. Node that there's not a ton of bandwidth on the channel, so try to keep the kbps small... sorry we don't have hard numbers yet: that's what the September launch if for ;)
On the ground, the CAN packets are distributed via a WAP using UDP... so if you have a laptop with an 802.11b card sitting near launch control, you'll be able to grab your packets as they come down the telemetry channel live.
If you'd like to integrate your data into RocketView, just let us know.
