i would like to see the display screens more like my old stile with double character hight and 10 screens. easier to read at a glance.

just no gps info. baud must be 38kb cause that is whay my xbees do.
earl

went back to gv9x109dump and all is ok.
btw...i did not notice a baud rate selection
earl

Screen 1 INFOS is correct so 38kb is working. I see the APM2 boot up properly and get the heartbeat indication
Screen 2 does not display any data. all fields are 0
Screen 3 is getting proper data.
Earl

Any thought with displaying MavLink data from an Xbee module ?
Earl

power output is variable by the menu. you can select +20 dbm(100mw)
Earl

No, other side just ground plane. No uC. 8s must control cypres chip via spi. But that can be a plus for us ! I did find in the manual the power is adjustable from -5dbm to +20dbm via software. It also reads all kinds of telemetry. We could even have this module do the spectrum stuff ! Heck, with th...

The shiel came off easy. Just do one end at a time. Just 4 blobs , one at each corner. I am getting close to powering it up. I'll try 3.3v then 5v and then 9v and 12 while measuring the voltage regulator output. I am pretty sure it is a 3.3vdc reg. I hope it's just serial data on mosi and msio pins....

I found mosi, msio, sck, and ss on the 2x5 header.

2x5 connector

MISO ?
MOSI ?
GND GND
SCK ?
SS +Vcc

This is my best GUESS. i have not hooked it up yet.
Just checked with ohm meter

Earl

Anyone got the pinouts for this board and the command structure? Is the telem RX on this board ?
Earl

3-1-12 It's here. Looks good. Small
Earl

The one problem I have is the initial bind process. Takes several minuets sometimes with turning the tx on/off holding training sw several seconds. No splash or warning screens turned on.
Any help here ?
Load rev 736 Blade mQX Quad. (flys great with 9x)

Earl

Yes it is high power, but the 5vdc in the er9x has a lot to spare, thus 5 > 3.3 is ok. You can use the battery voltage if your not sure.
I use a 2c lipo so I have ~8 vdc on battery side.
Earl

C12 and C14 are the input and output caps. Can also be reused. + is 5vdc or so input and 3,3 is the regulated 3.3 vdc output. the - is the ground side of the regulator. The diagram is good.
Earl

see my post about sending me a SASE and I will send you one free. I have a bunch here. I would never use them all.

You need a separate 3.3v regulator. Run it from the 5v line in the TX. I have a bunch of 1.5A 3.3v regulators. That is what I used. Sens me a SASE and I'll send you one along with 2 10uf caps you will need.

I think I will get one to experiment with....
Yea ! I ordered one...$13.85 delivered ! Let's see what we get.
Earl

was shipped today 2/20/12 via Hong Kong air mail! let's see how long to get here.

Here is some pics for the how to...

Boy is it fun to fly my Blade quad with the er9x ! One thing I noticed is the THR and ALE switch doesn't work, then I realized I didn't do the hardware mod of moving the 2 wires on this er9x. I have 3 of these things now so it's hard to keep track of what I have done ! Flying the quad with the er9x ...

Pat here is the eprom file.
I hope this helps get to the bottom of the results.
Earl

Not sure...I will look into it after I have a little fun first.
Earl

YEA !!!! using - on the mixes for YAW and ALE changed direction to correct orientation ! The INV do NOT do it.
Thanks PAT.
Earl

Thats what I thought also Pat but the inv does not seem to do a thing on the quad in the X configuration. I will try to put it into the + configuration and see if it helps. Also the YAW is reversed.
Earl

Still have the left/right reversal problem...

DSM2 broke in rev 701. as soon as you set the dsm2 mode in a model, it keeps resetting...

***** reloaded software fixed problem ******

Still have the right/left direction reversed...
Earl

Thats because Arabic reads right to left.....ha...ha..
Earl

I will try reversing the control on power up and see what happens.
Earl

Well things are working ALMOST...left and right on the quad are reversed. I have tried INV on ALE and ELV and it seems to have no effect. I haven't tried the rudder control yet. It should be the YAW. But overall, flying my mini quad with the er9x is GREAT. I bet the boys at the hobby store will be i...

FANTISTAC !!! it works...Thanks
Earl with Blade quad

ok it binds now but no throttle. Do I need to change order from reta to something else. I am trying to flt a blade quad Qsm
