I finally got it. the baudrate and parity were both wrong. So that's
working well enough to read the vfd's status bits with an
hy_comm-ok=true.
Now, to transfer controls to hy_vfd. And that is a mine field with this
man page. I gives a list of pins, but its a WAG what each does.
Fur instance, what the heck is bracking? If its misspelled braking for dc
braking there would be 3 values, 0 for coasting tops, 1 for resistor
stops (which I've not yet hooked up), and 2 for dc stops.
And this is confuzin
<name>.spindle-forward
(bit, in)
<name>.spindle-reverse
(bin, in)
<name>.spindle-on
(bin, in)
What the heck is a (bin, in) ??
And that isn't the end, that man page needs help. I don't like netting
$tuff ju$t to $ee where the expen$ive $moke comes out.
So first is adding a 10 second timer to run the hy_vfd.enable line 10
seconds after powerup. No use trying to talk to it until its booted
which seems to take about 8 seconds.
Thanks Andy.
Cheers, Gene Heskett
