Yes a small 10 inch laptop could do the work, predict would be used and

I'm looking at using a mini2440 board for just such a thing - ARM9 CPU,
masses of GPIO, a couple of serial lines, USB host *and* slave

Assembler is the right choice
Sounds nice.
One thing I have to keep an eye on is power being drawn from the USB if I am
to use any sort of relays

I use this board for many project excellent kit and also excellent

I am re-visting a rotator controller.
I am curious, should I push the processing of the compare and make a
decision
onto the PIC, or pull that function back into the PC ?
PC is LINUX
I/O is serial
I built a homebrew rotator controller, inspired by WB4APR 'Radio Shack' rotor
Thank you

Wouldn't you like flashing the pic with the G6LVB tracker firmware and make
the circuit?
Hi Andrew,
I have a PIC based solution currently in the prototype stage. It uses a
PIC18F4455 and drives a Yeasu AZ/EL rotor without the Yeasy control box.
The PC sends information to the PIC (RequestedAZ,RequestedEL) and the PIC
sends back status information to the PC
Hi Andrew,
Let's take azimuth as an example. The PC sends a string containing the ascii
value of the required azimuth. That value is converted to a binary value.
That binary value (0-360) is converted to an expected 10-bit ADC value
(theoretically 0-1024) for that angle.
The range I get from my
instead of
A/D etc
My 2 cents Alan

I'd like to suggest that such systems should have a compass

have such a rotator strapped in the back of my truck, and be
able to have it track
