Hi,
Folks, out of sheer curiosity, I am trying to build a "robot" buggy and want
to write the code on the Miggy.
There are two ways to control the motors.
1) I send the data to a DAC via a latch and that gives an analogue signal
to a VCO that drives the motor/s.
2) I send the PWM waveform down the data lines. Yes a bit more brutal, but
more controlable.
So I am wanting to know how fast the Miggy can "slit data out the Parallel
port"?
If I go for the latter, I will need a fairly good speed.
All that aside I am also going to need help with building the "interface",
as I have no real blitz knowledge.
The code is a few days/weeks off yet.
Would anyone be interested in please helping me with it?
I am guessing that the first way could be done with AREXX even, but the
second MUST be in blitz.
The "gui" will be 2 sliders. One for each motor. Maybe a "speed" at the
top of them too. ("speed" aka frequency.)
There may also need to be a "trim" control, so if one motor is slightly
slower / faster than the other one, I can trim it so if both levers are at
the same position, the vechical goes straight(er) than it would if the trim
was not there.
Maybe 3 levers. 1 for each motor, and a "common" one too. So only when
turning I use the specific one for the motor.
Anyway; I don't want to go on about it. That is the basic idea (scuze the
pun) and I am just asking.
Anyone? :-)
Cya!
