737NGX OFFSETS FOR REVERSE THRUST.

[mounty 13]

Hi,

 

I am having trouble with assigning offsets for reverse thrust using FSUIPC.  I enter the custome control number (70312 for #1 and 70313 for # 2) and have tried using the 0 and 1 to set the parameter but it doesn't have any effect on the 737 thrust reversers - no movement.  Any ideas where I may be going wrong?

 

Many Thanks

Hi,

 

Try with 16384 and 8192

This is how I set up the reverse button on my Saitek throttle:

 

 

The Parameter of 20000000 is the value for a left mouse click.

Thanks LRW, works fine now.  Didn't know it was 20000000 for a button press - will remember for future offsets.

One odd thing about the 20000000 value I gave you.  It's actually supposed to be the hex value x20000000.  From the PMDG_NGX_SDK.h:

 

#define MOUSE_FLAG_LEFTSINGLE    0x20000000

 

which is the same as a decimal value of 536870912.  I forgot to include the 'x' prefix in FSUIPC (not '0x' because FSUIPC will only store the '0'), which means that it's sending a decimal 20000000, but it still works.  With logging turned on in FSUIPC I can see it sending two different values depending on whether I include the 'x' or not, but I get reverse thrust either way.

The mouse flags in the header file appear to be standard mask values and it looks to me like the decimal 20000000 should not work because it does not include the bit that is set by the correct x20000000.  Maybe someone more knowledgeable with FSUIPC or the SDK can explain it.
