How do I calculate the CAN arbitration ID right?

Hello Again!
From my partner firm I got a scheme to calculate the extended arbitration ID. The bits are devided like this:
- 6 bit 5bit 1bit 3bit 4bit 5bit 5bit
The values got to be in decimal:
- 32-31-0-1-0-0-1
I figured out the following arbit.ID in Hex, but it seems to be wrong:
107C4001
This happend with the attached ID.
Whts wrong?

I tried to analyze your trace, but I don't see how it can be correct. Here is what I would expect to see (now, I could be wrong, but this is based on my calculations)
With your original ArbID of : 107C4001
SOF              29-bit ARB ID
0    1 0000 0111 1100 0100 0000 0000 0001
But, the 29-bit protocol states that you send the 1st 11-bits followed by SRR and IDE (both recessive)
SOF 1st 11-bits    SRR IDE   Remaining 18-bits
0    100 0001 1111   1 1 00 0100 0000 0000 0001
But, we need to account for bitstuffing (5 consecutive identical values results in an additional bit, deliniated with a ^ under it in my image),
so I would expect to see the following on a scope:
SOF 1st 11-bits      SRR IDE   Remaining 18-bits
0    100 00011 11101   1   1    00 0100 00010 0000 10001
            ^     ^                        ^       ^
What you saw was:
1011 1110 0000 1000 1101 1111 0111 1101 1111 0011 0111 0001 0101 0010 0001
<< Remove Bitstuffing >>
1011 111 0000 000 1101 1111 111 11 1 1111 011 0111 0001 0101 0010 0001
<< Compress, Assume you skipped the SOF and sent a 29-bit arb id >>
101 1111 0000    0   0   0 1101 1111 111 11 1 1111 011 0111 0001 0101 0010 0001
1st 11 bits    SRR IDE
SRR and IDE are both dominate, which violates the CAN spec for a 29-bit id. This could be an 11-bit ID, which would have SRR and IDE both dominate to send a data frame. However, afterwards you have r0 and DLC which should be recessive and <=8 respectively, which are really dominate and 13.
<< Compress, Assume you skipped the SOF and sent a 29-bit arb id >>
101 1111 0000    0   0   0 1101 1111 111 11 1 1111 011 0111 0001 0101 0010 0001
1st 11 bits    SRR IDE r0 DLC
So, I think you have either misinterpreted the scope or did not capture the entire transfer.

How do i calculate the average of runs that have variable number of samples?

Hi
I am trying to calculate the average trajectory from lets say 4 runs, with varying sample size.
That is, if the the 4 runs have 78,74,73,55 samples respectively, How do I calculate the average of (78+74+73+55)/4 , (78+74+73)/3 and (78+74)/2 and 78/1 ?
Thank you

I'm not sure you gave a sufficient information. Assuming that you just want to calculate a linear average of the data collected in consecutive runs, you have two simple methods :
1/ concatenate the data before calculating the mean.
Simple, but can occupy a huhe amount of space since all the data have to be stored in memory
2/ store only the means Mi and the corresponding number of data points ni and calculate a balanced mean : M = sum (ni x Mi) / sum (ni) )
The attached vi illustrate both methods.

How do I calculate the total size of selected folders?

Hello
My question is:
How do I calculate the total size of selected folders?
Thank you

It does show the aggregate size.
Command-Option-I opens the Inspector window. (Or open the File menu and hold the Option key. Get Info turns into Show Inspector.) The Inspector is similar to the Get Info window but it shows aggregate info for multiple selections. It is also dynamic — if you change the selection while the Inspector is open, the info changes to reflect the current selection.

I wanted to know how do you calculate the number of days between two dates

i wanted to know how do you calculate the number of days between two dates in java ? i get both the dates from the database. i guess there are many issues like leap year and Febuary having diff no of months ..etc.

thanks..
I solve my problem as
public class MyExample {
    public static void main(String a[]) {
        String stdate = "2009-03-01";
        java.sql.Date currentDate = new java.sql.Date(System.currentTimeMillis());
        java.sql.Date preDate = java.sql.Date.valueOf(stdate);
        System.out.println(currentDate);
        System.out.println(preDate);
//        int dateCom = preDate.compareTo(currentDate);
//        System.out.println(dateCom);
        long diff = currentDate.getTime() - preDate.getTime();
        int days = (int) Math.floor(diff / (24 * 60 * 60 * 1000));
         System.out.println(days);
}

How do I calculate the Out_flags number for the PIPL?

Hey everyone!
I'm kinda new to After Effects programming, so I hope I'm not asking a too obvious question.
I've searched the web and this forum but just couldn't find a working solution for this problem.
Compiling my plug-in works properly, but as soon as I select it from the effects menu I'm presented with a mismatch error.
My question (as already asked in the title): How do I calculate the correct number for the pipl global_out_flags?
Thanks in advance,
Markus

You will probably get a faster answer here: After Effects SDK

How do i calculate the scrollpane value

hi all, how do i calculate the scrollpane value dynamically?
thanks a lot

hi sorry for the lousy information, because i was in the hurry.
hm... should be describe in this way, in VB i know how to get the value of scrollbar when the scrollbar being scroll, but i do not know how to done it in JAVA.
i have my sample code as following:
        sp.addComponentListener(new ComponentAdapter() {
            public void scrolled(ComponentEvent evt) {
                width = getWidth();
                height = getHeight();
        });any idea? izzit correct? it just show nothing while i use to print at console

How do you calculate the count in before a cue start?

Here's what I can't figure out.
I have a quicktime loaded and I need to start a cue at, let's say, 1:05:07:10. I want the tempo to be, oh, 120. I arbitrarily say - this will be measure 41 but it doesn't really matter, I just need my downbeat at that TC and the tempo to be correct.
So far so good. I have no problem doing this with Tempo operations. I lock the time code, assign it a measure (in this case 41) and have logic calculate a single tempo from 1:00:00:00 (measure 1) to the desired start.
Now here's my real question. How do I calculate 4 or 8 beats before 1:05:07:10 so I can have a count it at the correct tempo (120)?
So I'm wonder how some of y'all handle this situation.
Thanks

As long as you are in the Fetch call, all other calls to the Scope
driver will block until Fetch exits. That's why the Abort doesn't
do anything. You have two options:
1) Use a finite timeout. Obviously, you are running into
cases in which the trigger does not arrive, and want to exit
cleanly. This is exactly what the timeout is for.
2) Determine the acquisition state before calling fetch.
If this is a finite, single-record acquisition, poll on acquisition
status and do not call fetch until the status is 1 (acquisition
complete). If you're doing a finite, multi-record acquisition,
poll on the Fetch>>Records Done property and only fetch the
records that have completed. If you're doing a continuous
acquisition, poll on the Fetch>>Points Done or Fetch>>Fetch
Backlog property and only fetch the number of points that have been
acquired.
There's no clean way to break the infinite timeout fetch without forcing LabVIEW to close.

How do I calculate the average of ONLY the populated fields?

I'm working on an Adobe form to streamline the process of summarizing course evaluations. To protect the anonymity of the students, instructors with 10 or fewer students are given a typed summary of the evaluation results. On the first half of the evaluation, the students are asked to rate a series of statements from 1-5. Three of these are highlighted on the summary form with the average response.
I've already set up the form with 10 unique boxes for each question and an 11th box which calculates the average. Each field is named according to the question number and the student's "number" (I arbitrarily gave each student a number so that each field would be unique):
i.e. #1. Questionquestionquestion. Q1S1 Q1S2 Q1S3 Q1S4 Q1S5 Q1S6 Q1S7 Q1S8 Q1S9 Q1S10 1AVG
The problem, of course, is that no matter how many students were actually in the class, the AVG field will always be calculated based on a group of 10...which isn't accurate or fair to the instructor. I thought about just changing the form and removing the unused fields from the equation each time I make up a new summary, but the point of creating a form was to make it as quick and easy as possible to bang these things out... Plus, some of my coworkers might be using the form from time to time and I'd have to explain what they have to do and if they don't have Adobe Acrobat then they can't actually make the changes and blah blah blah...it just gets ridiculous really quickly!
So anyway, I tried reading some other posts for similar questions in an attempt to figure out a custom calculation script for myself, but I just couldn't focus on it.
I was hoping someone could explain how to write a custom calculation script that will omit any fields which are left blank... Or, even better...is anyone willing to write it for me? At least just an example of the first guy, cause I could probably figure out how to get all the other ones from there.
Thanks.

In formcalc the function Avg will calculate the average of only the fields with a value in them. So you would would put in the calcuate event of the average field:
$ = Avg(Q1S1,Q1S2,Q1S3,Q1S4, etc)

How do I calculate the difference between two times?

I am so embarrassed by the fact that I can't figure this out.
Cell B2- 8:00 am
Cell C2- 10:50 am
Cell D2- (How do I get this cell to calculate the difference and say 2:50?)
I know this is probably one of the most basic operations, but for the life of me I can't figure it out. Cells B2 & C2 are formatted for 24 hour clock. But if I tell the system to just subtract the two, I get "0.118". Everything I find on the forum search goes beyond what I need. Can anyone help me?
Thank you.

How do i calculate the dates in this scenario

I have a situation here and i am not able to think through it
there are 4 date columns in a table and i need to do something like below
First Record start date is the start date, and end date is the next start date -1
Next start date is next start date, and end date is the first end date of the record set of the end dates
Next start date pervious end date + 1 and end date is the current end date
Next start date is the current date and next end date is the current end date
for example lets say we have a table like below
CustomerID CustomerType CustomerEffDt   CustomerTrmDt CustNationalBgnDt CustNationalEndDt
1                  National           2013-08-05        9999-12-31
2010-11-08            2011-11-02
Now my question is, we would have to calculate the customer effective start and begin dates and national begin and end dates based on the above criteria
we would have to create 4 rows based on the above scenario

After load .dbc file to the MAX, How to get activate the CAN signals?

Actually, i am new to labview and have some basic concepts. I am working on the CAN signals. I want to get activate the necessary signals alone. I know how to load the .dbc file to MAX. But after loading the .DBC file to MAX, i dont know how to activate the wanted CAN signals alone. For example, if i need to activate and control the speed CAN signal alone. i am not able to activate it.
