Sounds like a nice setup. I assume your board has to include some AtoD chip and the like. If I were to build one with a different Non Basic Micro platform, I would be tempted to use an Arduino Mega as It already has 16 analog channels as well as a ton of IO lines. But the current version with the Bap28 is serving me well!

Yes, I'm going to use a MCP3208 8ch 12bit ADC. As your probably aware the propeller doesn't have an onborad ADC.

Yes I noticed that when I ported the phoenix code over to a propeller. luckily the default phoenix does not have any required use for AtoD but it can always come in handy, for doing things like checking the voltage of the battery...

This sounds very similar to what Quantum (Paul) are working with:

Found some cheap Hitec Laser 4 radios. There trainer versions but the hardware should be the same. I picked up two and there's still 4 left.

You might be interested in this radio:
http://www.hobbyking.com/hobbyking/stor ... oduct=8991

It is a fairly good hardware, only the firmware is... crap.

Hence, some people made a new one:
http://code.google.com/p/er9x/

I did that, and ended up with:
16 channel (!) 2.4GHz all-purpose radio (you can link 2 8ch Rx at the same time, the 2nd one will then manage ch 9-16)
backlit screen
2-cell "protected" Li-ION battery - takes forever to discharge (20hrs or so)

and cheap, too.


BTW:
If you replace the original 2,4GHz system with the Jeti-Kit, you'll get the Jeti telemetry-return signals on the Tx display (no Jeti-Box required)

Hi all,
I did a little more research on the input to the Spektrum DSM2 Airmodule and found that the input is intended for an open collector signal. I do not know if this has been mentioned in this massive, but informative thread.
I intend to use the DSM2 Airmodule with an Endurance RC PCTx and was determining how to interface the PCTx output to the DSM2 Airmodule. To get the signal polarity right, it looks like I will have to have the PCTx drive a PNP transistor hooked to the DSM2's open collector input.
Just a thought.
Regards,
TCIII

Hi all,

Take a look at this joystick ppm encoder and Tx interface: http://www.ianjohnston.com/content/inde ... s&Itemid=8

Uses an Arduino Nano, but can use just about any Arduino processor board. Comes complete with schematic and code.

Regards,
TCIII

Hi,

I am hoping that someone might be able to help me here. I have all the parts to complete this project and have tested the code. I have been able to get the keypad working however when it came to moving servos with the joysticks I could move them so far and them nothing!!! It like the recever would not respond!!! I had no problem doing the bind between the TX & RX but i think it might be the different readings of the joysticks themselves. I got them from Lynxmotion (Part No: GIM-02) and when I did some A/D reading of the pots it got 0 - 1024 on the X & Y axes. So my question is has someone here used these joysticks????
Is it possible that you made be able to help me to get the correct readings so then I can adjust the code posted to get this thing working. Is there something I have misted!!!!


Code:
     1024                    1024
       |                       |
       |                       |
0------o------ 1024     0------o------1024
       |                       |
       |                       |
       0                       0


Any help would be great!!!!!
