Still no working LVARS more than a byte

[MarkStallen]

Probably doing someting wrong

In ini : 13=A32NX_HYD_BRAKE_ALTN_ACC_PRESS=SD66D5

If I list the LVAR with FSUIPC value=1576.3274

If I look at the LVAR (offset 66D5) in the monitor I get with SIF32 : 0.01953125 with S32 : 5

I tried several diferent assignements aswell in the ini file as in the monitor. I can't find the right couple.

If writing as SD (signed Double), you need to read as a FLT32.
Alternatively, skip the size:
    13=A32NX_HYD_BRAKE_ALTN_ACC_PRESS=0x66D5
and read as a FLT64.

S32 is a signed 4 byte value and will be an int, SIF32 is a 16bit/2byte integer + the fractional part in 16bits/2bytes.

(see P13 and P43 of Advanced User Guide)

If I use SD and FLT32 or 0x and FLT64 then they both give 0.0000000

If I list the Lvars with FSUIPC then the value = 1576.3274

I really don't understand because all my other lvars are working, but as soon as it's more than one byte it doesn't. in my ini :

[LvarOffsets]
0=A32NX_BRAKES_HOT=UB66C1
1=A32NX_AUTOBRAKES_DECEL_LIGHT=UB66C2
2=A32NX_AUTOBRAKES_ARMED_MODE=UB66C3
3=A32NX_MASTER_WARNING=UB66C4
4=A32NX_MASTER_CAUTION=UB66C5
5=A32NX_PARK_BRAKE_LEVER_POS=UB66C6
6=A32NX_ECAM_SD_CURRENT_PAGE_INDEX=UB66C8
7=XMLVAR_Baro1_Mode=UB66C9
8=LANDING_2_Retracted=UB66D0
9=LANDING_3_Retracted=UB66D1
10=LIGHTING_LANDING_1=UB66D2
11=LIGHTING_LANDING_2=UB66D3
12=LIGHTING_LANDING_3=UB66D4
13=A32NX_HYD_BRAKE_ALTN_ACC_PRESS=0x66D5

Ah...if using 8 bytes, then the offset needs to be aligned on an 8-byte boundary, e.g. last digit must be 0 or 8. Similarly, if its 4 bytes, ir must be aligned on a 4-byte boundary, eg last digit 0, 4, 8, or C, and similarly for 2 bytes (last digit 0,2,4,6,8,A,C,E). I will add this to the Advanced User guide.

Try the following:

0=A32NX_BRAKES_HOT=UB66C0
1=A32NX_AUTOBRAKES_DECEL_LIGHT=UB66C1
2=A32NX_AUTOBRAKES_ARMED_MODE=UB66C2
3=A32NX_MASTER_WARNING=UB66C3
4=A32NX_MASTER_CAUTION=UB66C4
5=A32NX_PARK_BRAKE_LEVER_POS=UB66C5
6=A32NX_ECAM_SD_CURRENT_PAGE_INDEX=UB66C6
7=XMLVAR_Baro1_Mode=UB66C7
8=LANDING_2_Retracted=UB66C8
9=LANDING_3_Retracted=UB66C9
10=LIGHTING_LANDING_1=UB66CA
11=LIGHTING_LANDING_2=UB66CB
12=LIGHTING_LANDING_3=UB66CC
13=A32NX_HYD_BRAKE_ALTN_ACC_PRESS=0x66D0

Then monitor 0x66D0 as a FLT64.

Thank you, that works.
