Hi Guys
Remembering I'm a novice and a bit of an old fart .. ... .
I'm having a play with stepper motors at the moment - I want to get some experience of how they work etc .. . I've got some steppers I saved from some old printers etc and I've identified them to type and found datasheets, so far so good.
I found a schematic to drive a stepper with a PIC 16f877A which I've now part built but the narrative says there is a 'switch' on the 16f877a which at logic high will drive in one direction and logic low the opposite direction. I've looked at the schematic and studied the datasheet but I cannot identify which pin is this switch - I find some of the abbreviations to pin labels a bit odd - .. .. ..
Can someone help me please .. .
Thanks S
