Cheap Idea for a DRO

[1113562]

Ah Sorry, I must have missed theat out of the installer script. (the inpout.dll is only required to handle the touch switch input on my panel-pc)

No not your fault :) I added the 'demo' option while testing the ADJ function, so I've only added X&Y to the menu. It will happily display four (or more) scales.

Each PIC has the same code, on power up each one detects the status of its pin5, then assigns itself as X,Y,Z or W. When the PIC detects a scale it informs the VB app, which then adds a display panel)

I use 1.5-2m screened cables (soldered to the scale). It would be wise to route them away from strong noise sources.


[edit] found a 600mm scale on ebay:

Hi Bill,
I have managed to program 4 off 12F675 PICS but for a quick demo breadboard can I just install 1 or 2 Vernier PICs into the RS232 interface driver rather than all 4. If so do I need to install X then Y then Z etc in that order. I'm getting to understand your assembly code but i've not quite figured out the TxSyn operation yet on GP4 in relation to channel time slots.

Cheers, John
