ASCII converter Web page?

Question

Has anyone come across a simple web-page based utility to convert text into ASCII codes?

It's always been a bit annoying to stop and look up all the codes from a table when coding, surely someone has made this easier for me.... What I mean is, if I am creating a series of messages that my embedded device will send over serial to either an LCD, or to a serial port, I take a message like "Hello" and create a block of text:

hello_data: .db 0x48 ;'H' .db 0x65 ;'e' .db 0x6c ;'l' .db 0x6c ;'l' .db 0x6f ;'o'

It would be nice if i could just type in the characters, and get something cut and pasteable into my work. I did arrange something in Excel once, but now I try and run it and I need an add-in that won't load - the hex2dec() function won't work properly, blah blah blah.

Any URL suggestions appreciated.

Cheers,

Ross.

Most assemblers I've used will accept things like.db "(C) 2005 Spehro Pefhany"All I've used will accept statements along the lines of: .db 'H'Best regards, Spehro Pefhany-- "it's the network..."

Sure. It's called an assembler.Good grief, where did you find an assembler that does'tunderstand ASCII character and string constants?  You need toask for your money back!I've been doing assemly stuff for 25 years, and have never seenan assembler that couldn't do this:  hello_data:  .ascii 'Hello'The syntax varies a bit from one to the next...  [Well I wouldn't bet that the CDC-6600 assmebler did ASCII, butit did know whatever 6-bit text encoding the system peripheralsused.]-- Grant Edwards                   grante             Yow!  ...

No need to look it up on a web-site. I use my Forth develoipment environment to do things like that for me. Compile the embedded strings from the plain text source and shove them into the memory array that you wish to allocate for it (often with a character count as well).This is the sort of thing you should be able to get your IDE to do with ease.-- ********************************************************************Paul E.

Ahh, a little perl is a beautiful thing. It's a very efficient language, but I'm afraid I've never used it enough to retain it any time I've learned it. Thanks for that, it works very nicely in Unix (Mac OS X) , I will use it often, as I am happy in the unix environment.

Thanks also to the others who posted suggestions & URL's.

Unfortunately my AVR assembler (MacAVRpa) doesn't take the direct text and convert it during assembly. (But it's free, so I won't ask for my money back.)

That sounds extremely primitive.  I'd swith to the Gnuassembler if I were you.  It's also free, but it's aprofessional-strength assembler.-- Grant Edwards                   grante             Yow!
