Hi,
I was wondering if i can use part of this code to calculate the most frequently occuring data, but not knowing what the data output is?
Or another wat to accomplish that?
So lets say i want to know the most frequently ocurring data samples from a windsensor (in m/s) from 60 one second samples.
'WS600Msmt is the variable that holds the result from the sensor Public WS600Msmt Public Mode(4) Public DestMaxSpa(2) Public WS600Mode 'count the occurrences of each mode and put the counts into 'an array If WS600Msmt = 0 then Mode(1) = Mode(1) + 1 If WS600Msmt = 40 then Mode(2) = Mode(2) + 1 If WS600Msmt = 60 then Mode(3) = Mode(3) + 1 If WS600Msmt = 70 then Mode(4) = Mode(4) + 1 'use MaxSpa to find the maximum of the Mode array 'the second destination variable is the Location 'within the array where the Max occurs MaxSpa (DestMaxSpa, 4, Mode(1)) 'Return a mode, based on which index in Mode() holds the max If DestMaxSpa(2)= 1 Then WS600Mode = 0 If DestMaxSpa(2)= 2 Then WS600Mode = 40 If DestMaxSpa(2)= 3 Then WS600Mode = 60 If DestMaxSpa(2)= 4 Then WS600Mode = 70
Look at the Histogram instruction.
Hi JDavis,
Thanks for your reply regarding the histogram function.
Ive looked at the histogram function some time ago, and found out it is a bit beyond my capabillities crbasic wise:(
But i will try it again:)
With the kindest regards,

Hi,
I found this example from the crbasic help.
Am i right in thinking that when i replace the 'public Tblock' with my precipitation type 'public Precipitation' code and change the LoLim and UpLim , it will woŕk ok?
With the kindest regards,
Mark
Public Tblock(2),BattV, PTemp DataTable( ACCEL, 1, 10000 ) 'Trigger, buffer of ,10000 Records DataInterval( 0, 1, Sec, 100 ) 'Synchronous, 100 lapses '-------------------- Thermocouple Blocks -------------------- Sample ( 1, Tblock(), FP2 ) 'Reps,Source,Type 'Histogram (src,type,disable,numbins,form,1,lolim,hilim) Histogram( Tblock(), FP2, 0, 2, 001, 100,10,30) EndTable BeginProg Scan (1,Sec,3,0) Battery (BattV) PanelTemp (PTemp,60) TCDiff (Tblock(),2,mV200C,1,TypeT,PTemp,True ,0,60,1.0,0) CallTable ACCEL NextScan EndProg
I believe ive got it working so far.
10 = rain
20 = snow
30 = sleet
40 = freezing rain
50 = hail
Ive set the LoLim to -5 and the UpLim to 55 with 6 bins.
But when the precipitation type is 10, it is visible in the hst(2) field instead of hst(1)...
With the kindest regards,
Mark
The histogram is working fine now:)
DataTable( Histogram_Precip, 1, 10000 ) 'Trigger, buffer of ,10000 Records DataInterval( 0, 1,Sec, 100 ) 'Synchronous, 100 lapses Sample ( 1, Precepitation_type(), FP2 ) 'Reps,Source,Type Histogram( Precepitation_type(),IEEE4, 0, 5,001,Precepitation_type(),0,55.5) EndTable
The next step is how to correct data, when my precipitation type sensor sees insects as precipitation.
With the kindest regards.
