Binary or BCD inputs and outputs.
« on: November 14, 2008, 04:18:18 PM »
Can you increase the inputs and outputs by specifying some of the parallel port pins as Binary or BCD? How? 4 bits would be good.

Thanx

Hi:

  There is an experimental mode for 5 bit multiplexing using the charge pump output as a multiplexor level sensor, if the charge pump is low, the input of 5 input bits on port1 is read as port 1, if the charge pump is low they are read as port 8. This allows for 10 input bits in total on port 1. This can only be done from a plugin by setting a system varible to that mode.

Thanx but you said low twice, i assume you meant high for port 8. Where can I get more detail on this?

Thanx

Hi:

 sorry about that, I did indeed mean low.

 Basically, ther eis a simple variable setting in the plugin system to turn on that mode. Are you now to the stage where you have a plugin?

No...I have barely just read your manual, everything about Mach3 is new to me. I am sure I have a learning curve. I will have a 2 or 3 test systems going next week, stepper, servo(closed loop), and gecko w/dc motors.

Thanx

Hi Buddy:

  I suggest you get everythign running with the typical 5 inputs.. its a large pearnign curve, adding a plugin to the curve probably isnt
productive at this point. When all else is dealt with you can start to worry about a plugin to swap the program to MUX mode.
