SYNOPSIS
loadrt histobins [count=N|names=name1[,name2…]]
DESCRIPTION
Read availablebins pin for the number of bins available. Set the minvalue, binsize, and nbins pins and ensure nbins ≤ availablebins.
For nbins = N, the bins are numbered: 0 … N-1
Iterate:
-
Set index pin to a bin number: 0 ≤ index < nbins.
-
Read check pin and verify that check pin == index pin.
-
Read outputs: binvalue, pextra, nextra pins.
(binvalue is count for the indexed bin)
(pextra is count for all inputs > maxvalue)
(nextra is count for all bins < minvalue)
If index is out of range (index < 0 or index > maxbinnumber then binvalue == -1. The input-error pin is set when input rules are violated and updates cease. The reset pin may be used to restart.
The input used is selected based on pintype:
| pintype | inputpin |
|---|---|
0 |
input |
1 |
input-s32 |
2 |
input-u32 |
3 |
input-bit |
Additional output statistics pins:
-
input-min
-
input-max
-
nsamples
-
variance
-
mean
The method input pin selects an alternate variance calculation.
Maintainers note: hardcoded for MAXBINNUMBER==200
