Help Please, I want to drive a 180 nm stepper manualley

<< < (3/3)

HS93:
I would still like to Go with your idea Chris as the display and the way you can tell it to go so far and stop is ideal for the things I do when milling plasticks. if you have any pictures of the inside of your it would be handy,

thanks john I have read the manual now and it is a good back up, I have several driver boars with the corect rating for the steppers already.

I can put the code to a PIC for you but it isn`t the best - good enough for me but was never really intended to share.

Basically the circuit is so simple. There are a number of pins on the PIC. One of which is +5V (so you need to make some sort of voltage reg.), the other ground, then their are a number of buttons. Finally one pin is connected to the step of the driver and the other is sent to direction of the driver and that is it! The PIC does all the work. I`m not really into electronics so the only thing I found a little tricky was the arrangement of a few resistors (pull up or pull down, I forget) on the buttons.

My daughter has now stopped crying so I`m going back to bed!!!!!  ::)   I`ll let you know more tomorrow and take some pictures after work.

Sorry Peter, missed this post totally, hadn`t seen any replies!!

I`m not going to lie to you, it has been a while since I`ve had out my EasyPIC  board so it`ll take me a couple of days to blow the code over to the chip. I`ll send a PIC out to you early to mid next week if you can get me an address via pm. I`ll post some pics on here when I find time over the next few days but other than the button/resistor arrangement, it really is easy. You`ll need a standard LCD screen if you haven`t got one. I`ll send you a photocopy of the info for that. Again, that is just a series of connections to to various pins on the pic all of which I can label.

Hope this is OK?

Chris

raynerd:
pm sent your way.

HS93:
thank you for that,

Peter
