OWOUT dynamic memory addresses

[scottl]

The memory is incremented by one each time a new datapoint is collected. I am looking at the samples counter to determine the mem_end location which depends on when the user does his rounds. If the user takes the reading early the next time it may be mem_end is 1045h so I will loop until: i = 0 to 45.

I will also add a loop from 0 to 90 and see what happens! So the OWOUT will send the data as hex without the "$"? I don't think I understand how the data is being sent via OWOUT.

mem_start = 0
mem_end = X  'Is dependant on the samples counter at time of reading

for i = 0 to mem_end
    OWOUT DQ, 1, [$CC, $F0, i, $10]
    OWIN DQ, 0, [TempRec]
    goto convert_temp
next i

Thanks,

Scott

Careful again... 45h does NOT equal "45" decimal.

It's being sent in binary. Use that Windows calculator, click on hex, enter 45 (or whatever) then click on binary. You can see the relationship this way.

mem_end = X  'Is dependant on the samples counter at time of reading

I just 'browsed' the datasheet. $CC command just skips the ROM. Data values are "N/A". I don't think you are going to get what you want with this code. Yet, I might be wrong because the last thing I need right now is 'learning' another datasheet.

Scott, I took a look at your posting history and something is becoming clear. You don't understand values (numbers, strings, etc.) and how the PIC (or any computer for that matter) deals with them. There are tons of good web sites that can help you understand how all these values interact and interchange with each other. I don't want to sound mean, but you have to get a better understanding of computer math, variable, etc..

{sigh}

I didn't learn these things when I was in school and I've paid for it all my life. I'm 46 years old and just now, it's starting to click.
