Hi Bruce and Hi to all,
new of this forum and new (less than new... just thinking about) of 2.4GHz!
I'm reading a lot about the subject and the most result is messing up all the news.
I use a MPX Royal EVO9, upgraded to PRO, but w/o PCM option and still with 2.62 sw. (35MHz)
I'm thinking to buy a FrSky Two Way system, as I'd like to have telemetry too, but the DIY hack module
hasn't that facility. Furthermore, I don't see any system that show data coming from the model, execpt, maybe, some alarms and led blinking on the two external modules for Futaba and JR radios.
Thus, reading about your project, I... saw again the LIGHT!
Nevertheless, need confirmation about the items I need: a two way FrSky receiver and a JR (or Futaba) external Tx?
I could also wait for FrSky DIY module with telemetry, but no one knows how long to wait for it.
Anyway, about telemetry I like your project and I'd use it for (in order of priority):
- rx voltage
- variometer
- GPS coordinates (...lost model find
)
- a second battery voltage or current sunk.
Your idea about a speech processor is absolutely good, as it is quite easy to loose your model watching somewhere else! (don't ask how I know it
)
Anyway, your choice about the lift and sink tones is unusual: low pitch and high pitch tone are usually heard for sink and lift respectively, both increasing frequency repetition according to their values. No tone for steady condition.
About GPS data, it would be nice to store them on a SD card while receiving and to show them on the display, only on demand (at least the last data received!)
A text only display with max four values displayed should be enough; if more than four variables are transmitted by the model, it should be possible to select which one must be shown on the display, but all stored on a card would be great!
Well, before giving any other suggestion, maybe it's better to understand more about the subject!
Thanks for your help, Piero.
