v1.7 - possible mod for free telemetry over BT with LCD

[Hamburger]

Hi,

since we already know how to setup a working BT connection between the LCD display and the arduino, we already have everything needed to utilize this as a telemetry service. No additional cost, no extra hardware needed.
For now this works with the TEXTSTAR LCD, because that has 4 buttons which I use to request one of 4 possible telemetry pages.
A - cycle time
B - Battery voltage and powermeter values
C - angles
D - nothing yet - maybe for future easy debugging inflight purposes.

For now user has to press button again to request update - this could be changed.
If you think this might come in handy tell me what values from the GUI (or from within the code) you would like to see in the telemetry pages.

In order to implement this I had to redefine the command letters Alex uses in Arduino and GUI code- hope that is okay.
Here's some photos -- no, limit is 256K here, too lazy to scale down photos, will post in RCG main thread.

I will upload code to Alex' google repository if someone is interested later.

Awesome, count me in.

wow, really nice.
So currently we have just to connect the Textstar LCD with 4 wires( VCC,TX,RX,GND) with the arduino and define it in the code and it works?

So i just need to buy that Textstar LCD?

+Bluetooth hardware for wireless

exactly.
If you buy BT modules make sure you can configure one module to act as master and autoconnect to the other module.
Also, both must run at 115200 serial speed.

sources are up here: http://code.google.com/p/multiwii/sourc ... rger/v1.7/

you will need both the arduino code and the modified GUI code.
In arduino code the command characters are altered to avoid conflict with Textstar telemetry codes
The GUI ist modified to accept altered command characters again.

ok, some news:
now the LCD buttons act as start/stop for continuously sending the telemetry data.
Besides, page A now has cycleTime and maximum cycleTime. Again, this can be disabled via a #define.

Works via bluetooth, which changes the flying/setup/checking/monitoring experience.
Just get the copter close enough to your BT telemetry box and use it. See, no cables neccessary.

Updated code is in google repository.
