PDA Controlling A Steeper Motor

[ceaser]

Hi Michael

I know that I can control the stepper motors through the RS232 port, as I have a program called Mach 3 and that can control the stepper motors from my laptop using the RS232 port. On my PDA (Recon) I have a USB and serial port. I have looked at the G-Codes, but they don't work for me!! I am doing something wrong. By the way the settings for the port should be "4800,N,8,2".

This is what I want to do:

On the PDA is a watered down version of my Land Surveying program. In the program I can define any alignment (ie. center line of a road, railway line, etc). The alignment consists of straight lines defined by coordinates called PI's (point of intersection). At each Pi is also a radius.

What I do next is to set up my base station (GPS) and connect the Rover to the PDA, which in turn is connected to the rover. This all sits inside a small Quad bike (which I stripped!). As the "car" moves along the centerline of the road the rover continously gets coordinates from the base station. Using these coordinates the program can calculate how far away from the centerline the "car" is and apply the corrections to the stepper motors to bring it back on track.

Please help

Thanks
Michael

Hi Ceaser, it would be useful if you could attach the pdf manual for the controller etc to your next post. If you dont have a manual then take photos of any face with connectors, writing or model numbers and attach them. Need more data before we can help in a specific way.Then we can have a look at whats inside the thing and maybe get you up and running. Your application sounds like fun, perhaps when its all working you could post a couple of pics of the thing in action. Jim
