Hi all,
i was wondering how you control a stepper motor...
in that way that you can control is speed...
i was thinking of a variable resistor...
conected to a PIC...
who measures the voltage etc...
but i don't know yet how to control the rpm of a stepper motor..
i also was searching for L297 examples
and should a pic 20Mhx (16F877a) be enough or should i go for a 18FXXX
then my last question...
is it easy for the pic.. to manage a serial eprom to be able to buffer data..
because large cnc progs maybe don't fit in the pic..
or should i give the pic his data realtime..????
TKS
