I can't externally latch the pins on the parallel port (from a 5 volt source). Does anyone know why this could be??
I am using visual basic to interface w/ the parallel port through Inpout32.dll. I have no problem outputting a high or low from visual basic but when I try to latch the pins externally (5 volt source) they won't change state let alone latch to the state I set them to. Any help would be greatly appreciated.
thank you.
