-4096 in Offset 0x088C

[carlosheviad@gmail.com]

Good morning Pete
If I send a value of -4096 to activate the reversals to offset 0x088C, I see that the value it actually receives is positive 61441, what am I doing wrong?
thank you very much

How are you setting this value? What FS and version of FSUIPC are you using?

And how are you reading the value? The maximum value of a 2byte signed integer is 32767 it looks like you are reading it wrong, maybe as an unsigned integer? The maximum value held in this offset should be +16384 (as described in the documentation).

Thanks Pete for the quick reply
I am programming my cocpit for Prepard 3D V5 with FSuipc 6 with Sioc scripts, the positive values are correctly received, from 0 to 16384, but when passing the negative sign, (if I send -1 it receives 0), (if I send -2 it receives 65535 positives), (- 3 = 65532)
Thanks Pete

As I said, how are you reading these values? Offset 088C is a 2 byte signed integer, and can therefore only hold values from -32768 to +32767. If you are seeing numbers larger than this, you are reading it as an unsigned 2 byte integer which has a range of 0-65535. You can verify this by logging the offset as both an S16 and an U16 using FSUIPC's offset logging.

Thanks again John, I was so anxious with the answer that I did not pay attention to who answered me, sorry, now I understand perfectly what is happening and I will try to remedy it
Thank you

Indeed John, read with Fsuipc an S16 the value is correct, an U16 is not
Thank you
