Post by thread:[PIC]: RS232 to Stepping motors

Hi! I'm just new to PIC and I have to work on a proyect for reading text output from a RS232 and drive two stepping motors from the values in text strings. Will you, please, tell me just the starting point? First I think in PIC16F84 but reading I think there are some others better for reading RS232 Is there any developer kit with 2 stepping motor control that let me start doing tests? Thanks in advanced :-) ________________________________ _______Jose Angel Navarro_______ _____welcome.to(ba/rra)janc_____ ___janc(arroba)altavista.net____ ________________________________ -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.

Hi, the PIC16F84 does not provide you with any internal support for reading RS-232. You might want to consider the use of an 16F8XX with a MAX232 chip. This is pretty easy. The stepping motor part should be pretty easy, you can find information about that on the piclist.

What about Dan's new botboard, it has 40pin PIC, serial chip, and motor driver chips for the stepper motors and many other goodies already! -Roman -- http://www.piclist.com hint: The PICList is archived three different ways.

To keep it simple, use a PIC with a UART. There are quite a few of these, see the line card. The cheapest is probably the 16C63A. If this is a one off or cost is not a big deal, I would use a 16F876. That gives you room for creaping features. ******************************************************************** Olin Lathrop, embedded systems consultant in Littleton Massachusetts (978) 742-9014, @spam@olinKILLspamembedinc.com, http://www.embedinc.com -- http://www.piclist.com hint: The PICList is archived three different ways.

Jose Angel, I have just finished the first phase of a rover where two stepper motors are controlled each one with a 16F84, and both 16F84s are coordinated by a third 16F84 which gets commands from a dip switch and communicates serially with the motors' 16F84s. This is similar to what you are trying to do. I am trying to find time to post the programs and drawings in my web page : http://www.ilari.org. Up to now, only the TRX routine has been posted but as soon as I finish my income tax return :-( I will post the remaining information I have about the project.
