Hi All,
I've built a parallel interface for my Futaba Skysport 4VF using the transistor scheme (1 transistor + 2 resistors). Firstly it didn't work, but I got some tips here and found out that i had to disable the sharing irq of my SB16 emulation (I got a SB Live). After then, my interface started working, but with an unsteady signal, in another words it seems that I'm flying in a very windy day. I have already tried to choose another irq for my parallel port, but things only got worse. Another interesting point is that the sound of the plane is awfull, tottaly "gapped" and unstable, just like the commands of the transmitter. I was wondering if building the serial interface would solve these problems, but I would like to hear some suggestions here before anything.
Second, is it possible to use this interface without spending my transmitter battery? Do I have to stick the full antenna not to damage the transmitter?
*Any* help appreciated!
Thx!
PS: I'm using Win98 and FMS 2.0 Beta 6.
