PinValues calculator
Since I had to switch to windows for some other projects I was working on, I threw together a quick pin value calculator in VisualBasic (hadn’t used that in forever!). It’s fairly simple and works on a 8-bit port - the right hand checkbox is pin 0 while the left hand checkbox is pin 7; a checked state is a value of 1 / on and unchecked is a value of 0 / off. You check the appropriate pins and click calc to get the hex value, or type in a hex number and click pins to see which pins are selected.
