MW 2.2, no arm/disarm with Turnigy ER9X

[Blue_Lion]

I installed WM2.2 on a formerly with MW2.1 fully working Quadrocopter, same settings.
Use Turnigy ER9X, mode2, HK_MultiWii_328P

1.) No arm/disarm possible, although all ranges for THR, PIT, ROL, YAW are between 980 and 1960
Enabled #define ALLOW_ARM_DISARM_VIA_TX_YAW, #define ALLOW_ARM_DISARM_VIA_TX_ROLL

2.) There is a lag in the THR, if I reduce from full to zero, it stops occasionally in the range from 1100 to 1400,
returns below 1000 only when stick is reduced very slowly!
There seems to be some faulty code in MultiWii.ino line line 936ff!?

Reinstalled MW2.1 again, works again.
Please help to find error!
I like the Multowii project very much!

I don't have that problem with MW2.2 and Open9x running on a Turnigy.
The behaviour of throttle and the other channels is as it should be.
The neutral position of the throttle is at 1502, the copter immediatly arms and disarms, when the outer ranges (less than 1000 or more than 1850) have been reached. I do not observe a lag. Are you sure that the configuration of the transmitter is correct?

[Blue_Lion]

Since it worked properly with the former code, I didn't consider any problems with the TX.
Arm/Disarm with sticks is not working any longer.

Working for me too. Tested on a 9x and 9xr with open9x.

It's working for me to. MWii 2.2. turnigy 9x with er9x.

[ardufriki]

Working ok with Turnigy 9x

Don't set low endpoint bellow 1000us !. Best set to about 1030us.

Same issue here with Multiplex PRO.

2.1 OK. With 2.2 no arm/disarm with stick.

Back to 2.1.

[copterrichie]

Just curious, would a total EEPROM erase help?

[scrat]

If it works with 2.1 them it must work with 2.2 the same way. I think no one change this code for arming/disarming. Set endpoints form 1000 to 2000 and it must work.

It looks like the bug i had when switching from 2.1-dev to 2.2-pre on my Crius AIOP board.

Motors where spinning around full throttle only.

I did eeprom erase then uploading the 2.2 release, and then it worked back again like it allways had to be.

Hope that will help

bonjour,
j'ai le meme probleme, en 2.2 probleme d'armement/desarmement...Il faut mettre le trim au minimum à 30 pour avoir quelque chose et de plus c'est aleatoire... Merci d'avance??

I have the same problem, problem in 2.2 Arm / disarmament ... We need to trim at least 30 to have something more and this is random ...?? Thank you

Look at the values the controller generates.

You can change thresholds here:

Multiwii.ino

(Because my controller generates cannel-values ​​in the range from 1055 to 1886)

// ******************
// rc functions
// ******************
#define MINCHECK 1100
#define MAXCHECK 1800

After some further trial I figured out that #define FAILSAFE is hindering ARM/DISARM.
Without FAILSAFE everything works fine.

Obviouly the TX9 is sending pulses below the set limit of 985µs.
Does anybody know where to set this parameter in MW2? Best would be to parametrize this in config.h

[copterrichie]

It would possibly work better by adjusting the end points in the transmitter.

Same problem here ..... no arm/disarm after updating to 2.2. I need to calibrate the ACC again, then it works .....

Like copterrichie said...just adjust endpoints in your Tx. I have TG9X with er9x FW. In MIX screen i have all channels set to 100%. But for endpoints all channels are from -97 to +97.

Just experienced the same problem. It's the failsafe kicking in when PPM level on thottle is too low from the receiver. It makes the multiwii have a hickup and you see angle-modes goes active, like you'd expect when failsafe kicks in. Thanks, great help everyone.

You must set endpoints. Channel must not go below 985us. It is better to have channels from 1005us to 1995us and you're good.
