I guess I don't understand how he used select8 > and wsums. So that I could use a single-deck switch, I used a diode matrix to encode the axis selector into binary code. Zero is not implemented, so that an enable switch has to be pushed to select an axis (or whatever) to jog. A schematic is linked to on the bottom of this page : http://pico-systems.com/pendant.html
This ends up creating 3 bits for up to 7 active selections (0 being reserved for nothing selected). So, the 3 bits are then sent into 3 inputs of a weighted sum, which then produces an integer from zero to 5 in the case I had set up. This is then sent to a select 8 as the sel input. The outputs of the select8 are then sent to enable jogging and feedrate overrides. Actually, putting all these things into one HAL component is more efficient. My code used about a dozen, I think.
