This is software for Palm- compatible hand held computers for use with AED's Rocket
Data- Acquisition System (R-DAS) flight
computer and desktop analysis software for Model and High- Powered Rocketry.
The current release (Version 0.0.4) is alpha, meaning
it is still under development but is functional enough to begin
testing, and soliciting comments from other users.
With your assistance and feedback we hope to
make this software the best it can be.

Version 0.0.4 alpha
|
|
This version adds help screens and cleans up some of the
communications code. There were several bugs fixed in the
configuration screens as well as the upload data screen.
|
Known Bugs
|
|
(All known bugs will be repaired in the next release.)
- Launch detect is zero
- Problem: Sets RDAS launch detect to 0g
- RDAS-Palm sometimes loses communication with the RDAS.
- Workaround: Restart the RDAS
- Uploading RDAS data from RDAS-Palm to the desktop AED-RDAS software
- Problem: Data may be incorrect
- Desktop HotSync RDAS Data Files are not readable by the AED-RDAS desktop software
- Workaround: use RDAS-Palm File--Upload to read data into the AED-RDAS desktop.

Version 0.0.3 pre- alpha
|
|
This is the initial release. It should be feature complete.
Some things might not work however, and there may
be debugging prompts and code still present for testing.

Requirements
|
|
- Palm- compatible handheld computer
- Palm
- Handspring
- Sony
- IBM
- Samsung
- Kyocera/Qualcomm Smartphone
- 425KB free memory
- (For Version 0.0.3/4: Serial type Palm Cradle)
The RDAS software for the Palm requires Palm OS 3.0 or later. The
program is only 42KB but the datafiles downloaded from the RDAS are
quite large, 384KB. You will need at least 425KB free and possibly
more to successfully install this software and download flight
data.

Features
|
|
The next release will have these features:
- Configure the RDAS flight settings (recovery options,
sampling, etc.)
- Download flight data and save it on the Palm
- Upload RDAS data directly to the desktop analysis software.
- Set calibration values for the pressure and
acceleration sensors.
- As soon as we can, we will support RDAS-Palm
connectivity via the infrared ports so a serial cradle
and cable will not be required.
Future versions may have these features:
- Flight analysis
- This will be implemented later
to allow you to see how high the rocket went, how fast it
went, when certain events happened etc.
- HotSynched RDAS Data Files
- Conversion of the
sampled data to the RDAS raw file format so the
datafiles, once HotSynced, can be read directly into the
desktop analysis software.
- RDAS Extensions
- Support for RDAS add-ons like
the igniter board and GPS module.
- Realtime Flight Telemetry
- Support for
integrating AED's realtime telemetry with the Palm.
- Kyocera Smartphone
- Support for sending realtime
telemetry to a web server for realtime web launches.

Cable
|
|
(Future versions will support the Palm's infraread "beam"
port communicating with the AED RDAS infrared module.)
An RDAS and a Palm don't mate directly as both the RDAS cable and
Palm Cradle (Serial, not USB) cable have 9pin female connectors. In
order to connect them you need a male-male 9 pin (M/M DB9) cable.
This adapter needs to be a "cross- over", or null
modem type cable. This means the serial transmit pin of one end must be
connected to the receive pin on the other and vice versa. Don't
forget the ground connection.

Documentation
|
|
The software should be pretty easy to understand if you have used
the desktop or CE software already. The menus contain the
following items.
- File
- Rename
- Rename a previously stored data file
- Delete
- Deletes the currently selected data file
- Download
- Download flight data from the RDAS
- Upload
- Emulate an RDAS so the desktop software can
download a selected data file.
- About
- Software authors' info.
- Configure
- Configure RDAS
- Similar to desktop software
config screen
- Calibration
- Calibration values for sensors.
Defaults should be fine.

Testing Status
|
|
- Version 0.0.4
- While we have done a good deal of testing, we haven't flown
the RDAS. (If we crash it we wouldn't be able finish the
software.) We can download and then upload data to the
desktop software but we can't verify it transfers correctly.
We would like testers to confirm that downloading data
to the Palm and then uploading it to the desktop software
is the same as downloading it directly from the RDAS.
