NAME

mux16 - Select from one of sixteen input values

SYNOPSIS

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.
sel3=FALSE, sel2=FALSE, sel1=FALSE, sel0=FALSE

out follows in0

sel3=FALSE, sel2=FALSE, sel1=FALSE, sel0=TRUE

out follows in1

mux16.N.inMM float in (MM=00..15)

array of selectable outputs

PARAMETERS

mux16.N.elapsed float r

Current value of the internal debounce timer
for debugging.

mux16.N.selected s32 r

Current value of the internal selection variable after conversion
for debugging
