Title: Hex to Decimal Conversion Post by: Rodger on April 15, 2011, 12:53:23 PM Hello
I'm using Advanced Serail data Logger and I'm parsing my data so I get a 5 digit ascii string in hex format: 03C4A6 03BC40 03E094 03F462 040952 03FBB0 03CC9E 039648 0357A0 033B44 032514 I would like to convert this to a decimal no. and then divide by 1000. I've tried the Expression plugin but can't see any functions that would do hex to dec part of this. I've tried various of the conversion functions but they talk about arrays and my data is a string not an array. Is it possible to do this within the logger and if so a solution would be much appreciated. Thankyou. Title: Re: Hex to Decimal Conversion Post by: Arthur Grasin on April 15, 2011, 03:42:51 PM Did you configure the ASCII Data Parser plugin to extract a single value? If yes, then please, download the update for the Expressions plugin and use the following expression:
Code: VALUE2=HEXSTRTODEC(VALUE)/1000 http://www.aggsoft.com/download/expressions.exe Title: Re: Hex to Decimal Conversion Post by: Rodger on April 15, 2011, 08:01:50 PM I found the function, thanks. However I can't get the variable I declare in the expression plugin to show in the DDE output. I've tried different expressions and none show up so I must be doing something fundamentally wrong.
I've attached a jpg showing how I've configured all the relevant screens. I hope you can help. Title: Re: Hex to Decimal Conversion Post by: Arthur Grasin on April 15, 2011, 10:02:57 PM This is a bug in your version. Therefore, I've suggested to update the plugin.
Title: Re: Hex to Decimal Conversion Post by: Rodger on April 15, 2011, 10:15:14 PM I've updated the logger as suggested, checked I'm on the latest version of the plugin and it still doesn't work.

Title: Re: Hex to Decimal Conversion Post by: Rodger on April 15, 2011, 10:39:04 PM OK
I've now got the expression appearing in the DDE :), I had to stop and start the logger before the changes worked. VAR1=HEXSTRTODEC(PDRDATA) works fine. However, VAR1=HEXSTRTODEC(PDRDATA)/1000 VAR1=(HEXSTRTODEC(PDRDATA))/1000 don't work. Title: Re: Hex to Decimal Conversion Post by: Arthur Grasin on April 16, 2011, 10:31:34 AM It works in my case :)
Title: Re: Hex to Decimal Conversion Post by: Rodger on April 16, 2011, 06:20:02 PM Fixed it here too.
Under the DDE settings tab the Number format was selected and set at 990.00, this was translating to the DDE number output for the Expression. |
