Yes, I pulled both TSX0108 chips OE to ground( but not through a pull down ). I've also tied the DB25 gnds to the Arduino in 2 places and tied those grounds to the ground of the 5V supply. Everything should know where/what ground is. Charles, explained it being the design of the part which does not provide pull down capabilities. I was about to order a few 74HCT245 parts. Still might just to have onhand. I ordered one of Jeff's boards. -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
