This is a special Feature for rotary Selector Switches. Instead of loosing one Pin per Selection you can turn your Switch in a Potentiometer by soldering 10K resistors between the Pins and connecting the Selector Pin to an Analog Input.
|
||||
The Software will divide the Measured Value and create Hal Pins from it. This way you can have Selector Switches with many positions while only needing one Pin for it.
|
||||
|

# 1 binary encoded Selector Switch input / absolute encoder
|
||||
# 1 binary encoded Selector Switch input
|
||||
Some rotary Selector Switches work with Binary Encoded Positions. The Software Supports Encoders with 32 Positions. (this could be more if requested)
|
||||
For each Bit one Pin is needed. So for all 32 Positions 5 Pins are needed = 1,2,4,8,16
|
||||
If this feature is enabled, 32 Hal Pins will be created in LinuxCNC.
