Stepper Drive Object

KenBash

I noticed that the Propeller·product·page mentions stepper motors.

I have an application currently running in Spin that has step, direction, speed and positioning for a single axis. It doesn't have·speed ramping yet, but the application doesn't really need it.

·I managed to stuff a 4 axis 24 bit·linear interpolative drive· into an SX-48, and suspect I can do the same better and easier with the Propeller, however it would be a shame to invest the time only to find out it was already done.

Is there a stepper drive·positioning function already out there?

heres a basic one that i wrote, and am using with a td62083 to raise and lower my linear transducer while its on the bench.. some modifications required

dan

ps stepper_linear_trans is the one i modified the other should run fine to test your stepper setup

Thanks Dan,

I'll try it out.

I managed to get a simple ramping function going this morning in conjunction with an assembly program, but I'm going to need something a bit better if I'm going to control multi-axis CNC and Robotic arms with it. I suspect I'm going to wind up coding it all in assembly from what I saw this morning.
