microstepping with l297
Hi,
If you have found a little development board that does motor control from the PC then great - sounds just the thing for you to really start learning with.
You don't say if you are programming in C, Basic or Assembler etc ?
As for USB, well perhaps I have not been able to explain it clearly, partly because I have not been able to try it becuase of my lack of knowledge of the program language C18.
To take one of the several Pic18F chips that have the USB hardware, you need a mass of complex C18 programming to establish a link with the PC, and only then can you start to program your code to send and receive data into your main program.
Don't think anyone would care to disagree that doing your own USB is for an experienced C programmer only...... anyone... ??
I don't want to discourage you from learning all about PIcs in any way, its a great interest and learing curve but think USB is a step too far for now.
Attached is a picture of a little board I made to teach myself about motors - its just driven from my 18F pic dev board controlled by switches and an lcd.
Bought the motors in a sale from a local model shop for just a few pounds/ dollars and they are driven by the L298 from the 18F
