Ok, following your advice I am creating an account on Git, and soon as possible I’ll share my little program.
I think is important to understand that my big problem was the little but costant movement of Radar ( or HSD ) cursor towards lateral sides, thas united with cursor bumping feature, behaved that in a little time the radar or hsd range was at maximum. I cannot solve this problem using standard bms parameters, so I introduced a little hysteresis that seems to solve this annoying effect.
Ciao.
