hello
i am now testing my home built fmc for 747 (from opencockpits)
when i try to write a value at offset 5428, only the first time and only once a caracter is displayed in the magenta cdu
by example if i write 65 at this offset a "A" is displayed in cdu but if i write 66 or 8 or another caracter, nothing happens !!!
i have tried to toggle some bits in the same time (of hight byte) but i am always the same trouble.
where can i find some examples or help to do this interface working?
Thank you
Patrick
