SYNOPSIS
loadrt mux16 [count=N|names=name1[,name2…]]
FUNCTIONS
- mux16.N (requires a floating-point thread)
-
PINS
- mux16.N.use-graycode bit in
-
This signifies the input will use Gray code instead of binary. Gray code is a good choice when using physical switches because for each increment only one select input changes at a time.
- mux16.N.suppress-no-input bit in
-
This suppresses changing the output if all select lines are false. This stops unwanted jumps in output between transitions of input. but make in00 unavailable.
- mux16.N.debounce-time float in
-
sets debounce time in seconds. eg. .10 = a tenth of a second input must be stable this long before outputs changes. This helps to ignore noisy switches.
- mux16.N.selM bit in (M=0..3)
-
Together, these determine which inN value is copied to out.
- mux16.N.out-f float out
-
- mux16.N.out-s s32 out
-
Follows the value of one of the inN values according to the four sel values and whether use-graycode is active. The s32 value will be trunuated and limited to the max and min values of signed values.
