Hi Luca. Check documents from
http://www.eutelsat.com/en/support/technical-support/diseqc.html
Maybe you find there what you want.
Thank you. I read those documents so many times but I managed to not see
the table on page 12 of the "Positioner application notes" one.
Duh
Bye

Hello,
In cDiseqcPositioner the last nibble (corresponding to the first
decimal) of the angle is calculated as
a % 10 * 16 / 10
With, e.g. angle -123 (-12.3) the resulting diseqc command would be
6e e0 c4
(i.e. the last nibble is 4 to represent 0.3).
OTOH the enigma2 implementation uses a lookup table for the decimal
digit:
.0 -> 0x00
.1 -> 0x02
.2 -> 0x03
.3 -> 0x05
.4 -> 0x06
.5 -> 0x08
.6 -> 0x0A
.7 -> 0x0B
.8 -> 0x0D
.9 -> 0x0E
https://github.com/OpenViX/enigma2/blob/master/lib/dvb/sec.cpp#L526
so for the same angle -12.3 it would send
6e e0 c5
(at least looking at the code, I don't have an enigma 2 receiver).
Since I'm implementing the receiving side and the only "reliable"
documentation is either the enigma2 code or vdr, I wonder which one is
correct.
