hex to dec conversion
Archiver
Posts: 46,084
Hi all,
Once again, not paying attention in math class bites me...
I am reciving the Julian date in BCD format from an Ultralink clock. I am
having problems converting it to dec format. I looked at Tracy's site, and
still couldn't get it to work. My code is like this:
rawYear var word
main:
serin 7,17405,10,No_Data, [noparse][[/noparse]wait("B"), hex3 rawDays
goto main
Now, if I add a debug which says:
debug hex3 rawDays, cr
Of course I get the right number. I just can't seem to switch it to DEC
format.
Thanks!
Jonathan

Euyear=(rawyear>>8)*100+((rawyear&$F0)>>4)*10 + (rawyear&$F)
I think that will work. You could make it easier by reading the bytes
separate:
serin 7,17405,10,No_Data, [noparse][[/noparse]wait("B"), a,b,c
year=(a-"0")*100+(b-"0")*10+(c-"0")
or maybe:
serin 7,17405,10,No_Data, [noparse][[/noparse]wait("B"), dec1 a, dec1 b, dec1 c
year=a*100+(b*10)+c
Something like that?

Substituting "days" for "years" in your code I get the same results I get
from code I made using Tracy's site. The current day (Julian) is 310, but
your code returns 011. I am doing days, not years, is that it?
Thanks for the help,
Jonathan

Hi Jonathan,
The calculation goes as follows:
decdays = rawdays.nib2 * 10 + rawdays.nib1 * 10 + rawdays.nib0
DEBUG DEC decdays, CR
That is the ordinal day of the year. The clock also gives a flag
that tells if the current year is a leap year or not. The code here
http://www.emesystems.com/BS2math4.htm#JulianDate
describes how to change the ordinal date into YY:MM[noparse]:D[/noparse]D format.
Which model clock are you using? <http://www.ulio.com> I have the
older OEM model that Parallax used to sell, now seemingly
discontinued. But the string you have, "wait("B"), hex3 rawDays"
does not match what I was familiar with. The old OEM model had a
choice of packed BCD or ascii BCD responses. I was quite hip to it
at the time, because I was beta testing the interface.

$33 $31 $30 (ASCII)?
Your original code says:
serin 7,17405,10,No_Data, [noparse][[/noparse]wait("B"), hex3 rawDays
The hex3 makes me think you are getting $33 $31 $30, right? Otherwise, that
might be your problem right there.

The code you gave, of course, works. I just made a little program to watch
all the math happen, and I think I get it. Maybe. Why wasn't I given the
math gene?
On your page it gives the formula:
DD = DD.nib1 * 10 + DD.nib0 ' BCD to binary conversion of day
Looking through the example code, I thought that would apply to me. Why
doesn't it?
I am using the old OEM module, the 325B, I think it is. The WAIT("B") is
because the Stamp is actually receiving the data from a 433mHz receiver. I
have the WWVB module hooked up to a 433mHz transmitter so that any of my
projects that need the time can get it using a cheap receiver, with no need
to include I/O or code for setting the time and date. It's a great system, I
have three projects using it so far and more to come. All I need is to get
the date going, (one of the projects finally needs more than the time) and
with your and Al's help, I think I have it licked.
Doh! I shouldn't have said that! Now I'll need to ask a question for sure!

It is BASICally the same. Except your example had three nibbles
instead of two:
serin 7,17405,10,No_Data, [noparse][[/noparse]wait("B"), hex3 rawDays]
That is because the day of the month only goes to a maximum of 31,
while the number of days in a year can go up to 365.
so you have to process three digits, the 100s, the 10s and the 1s.
decdays = rawdays.nib2 * 10 + rawdays.nib1 * 10 + rawdays.nib0
The formula assumes you are comfortable with the BASIC Stamp's left
to right way of doing its math, which in most math books you would
have to write with parens as follows:
decdays = (rawdays.nib2 * 10 + rawdays.nib1) * 10 + rawdays.nib0
so rawdays.nib2 ends up getting multiplied times 10*10. By the way,
the Stamp produces the same code with and without the parentheses.
Alan suggested a formula that sets it up a little differently, but
gets exactly the same result:
DecDays = (rawdays.Nib2 * 100) + (rawdays.Nib1 * 10) + rawdays.Nib0
In this it is plain to see the place value of each nib as 100s, 10s and 1s.

That's a neat idea. The original app we had for these was for a
study out at Point Reyes Nat Park after the Mt. Vision fire, to time
the incidence of runoff from the high slopes, to see how long it
would take to build up a flash flood in the lower reaches near the
bay. The data loggers at the high and low locations would have to
have very accurately synchronized clocks. But the WWVB reception in
the Canyons was impossible. Your idea of a "relay station" at the
top might be workable for that kind of situation.
-- Tracy
0x08, 0x09, then 0x10, 0x11
Note this skips the values 0x0A..0x0F.
Binary (and Hex) goes as:
0x08, 0x09, 0x0A, 0x0B, ...
So a BCD coded 'byte' can go from 0..99,
while a 'true' binary number can go from
00..FF, aka 0..256. Thus the conversion
is needed. If you're talking about number
of days per year, that's more than 256, so
you need a third nibble for top 0,1, or 2.
