Dear Sirs and Madams.
I am relatively new to electronics in that I can follow instructions but not design too well. I am trying to build a stepper motor system controlled via 4 pins on the parallel port say D0-D3 (I am a software developer by nature).
Well, you see, it takes someone really smart to develop this kind of electronics stuff, us coders hack and still get it wrong.
Anyhoo
I have a stepper motor in mind which /* should */ have most of the required bit already in place. the SYiNTSD232#2 at Zapp Automation
The problem with these hybrid stepper motors, as fancy as they are, I have no idea what to put between the parallel port pin and the input of the motor. The documentation specified the input is 3.3-5V at between 5mA to 20mA. From research I understand that a given data pin can produce 0.5mA.
So how do I rectify this (I've put 2 lines in to represent broken circuit - error)
Any help would greatly be appreciated.
