Stepper motor controlled by small Pic 12Fxxx ?

[zorgloub]

Hello,

I would like to order a stepper motor with a small DIL8 Pic (12F 683-675-629) followed by an L293D Dual H Bridge.

The sequences to be output are (in decimal): 9,5,6,10.

This Nibble must appear on ports GP0-GP1-GP2 and... GP4.

Not on GP3, which is only an input and reads the voltage from a potentiometer!

What "simple command" can I use to output my nibble on the 4 output ports mentioned above (GP0-1-2-4) without interfering with the GP3 input port?

With a Pic that had 4 contiguous outputs (which is not the case here), we would simply have written something like PORT A = 5 ...

Thanks for your help.

Same here. If pin is input, writing to GPIO does nothing for that pin.
So just make binary combination that is disired, and write to GPIO.

Thanks for your quick reply Pedga089.
OK, thanks, I note that writing to the GPIO register will not affect the GP3 input.
So the command in Basic is as easy as I was declining in my request. Great ;))
Have a nice day

Salut à toi machiavélique AceTronics ;)
Je vois que tu connais tes Classiques :))
Je vais aller revoir ton lien très intéressant.
Les codes sont cependant en C me semble t-il...
Bonne journée à toi.
