Hi All
I'm back from a RELOCATION in taiwan and from now on,
I'll try to log in every day (As usual)...
and ask & reply questions... and doing some of my
personal projects.

So lets start with question
A Very hard issue for me...

I Need to make a Multi Voltage Junction, controlled by
89c55 (8051) This junction should support the following
voltage levels: 0V 3V 5V 12V, and supply up to 100mA
Also Need to be with minimum componments
(less than 4 transistors), And I Need also to sample the
Junction voltage level with the 8955.
I Can use any or all kind of supply voltage (up to 12v)
Unlimited resistors, and 3 transistors.
I Have Left only 3 IO Pins from port2 to do this task.
Thanx
OK
