CheckForChanges

CheckForChanges
Polling function to check changes Returns 1 for chaged, 0 for no change, 255 for error 
- BYTE Return


Disable

Disable
Disables the use of the quad encoder Once this ist called, the read functions will return zeros until the next Enable() call 
- VOID Return


Enable

Enable
Enables the use of the quad encoder If this is not called, the read functions will return zeros 
- VOID Return


ReadCounter

ReadCounter
Reads the current dial counter This is a counter from -32768 to 32767 
- INT Return


ReadCounter32

ReadCounter32
Reads the current dial counter as a 32-bit value This is a counter from -2147483648 to 2147483647 
- LONG Return

Property reference

Properties
Count Variable
Variable Type
Selects the size of the encoder count variable depending on the number of encoder counts required to be stored. The 16 bit variable counter is accessed via the ReadCounter and WriteCounter functions. The 32 bit variable counter is accessed via the ReadCounter32 and WriteCounter32 functions. 
Encoder Resolution
Post Scaler
Encoders with a mechanical click will often have 4 transitions per click. 1:1 would provide the maximum output resolution. 1:4 would provide the encoder click count. 
Edges Per Revolution
Number of signal transitions per revolution. E.g. for a 360 degree encoder you would likely get 360 x 4 = 1440 transitions and an accuracy of 0.25 degrees. 
Resolution
The resolution of the encoder in degrees 
Connections
A
Input pin A 
B
Input Pin B  
Simulation
Repeat Rate
Simulated repeat rate when clicking and rotating the encoder
