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 nbinsavailablebins.

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
