reading ASCII coded Hexadecimal data from serial port
Hi,
I'm trying to get (and numerical manipulate) hexadecimals from my serial object. Everything is working fine, but I can't manipulate the hex symbols after I've used the itoa object.
I'm getting -> error: number: doesn't understand "0x001E"
Seems like it's interpreted as a characrter
Any ideas?
First, it looks offhand like you've got a right-to-left order problem between the serial and gate objects. You may need to reread the relevant tutorial and look at the trigger object.
Second, 0x001E is not a number in Max, it's a symbol (cf the thread on 'minor confusion'). Number boxes don't grok symbols (that's tutorial, what?... 3? 4?).
Just connect serial's output (or match's output) to a number box. If you want the numbox to display in hex, use the inspector.
I think it's a bit easy to react this way. It's not about displaying the hex code, but manipulating the data. From the serial object I receive ASCII. I want to translate that to hex numbers to make calculations with.

Go to maxobjects.com, search for hex, and pick up one of the external
listed here. For example, Llong (from Peter Elsea) seems to achieve
what you want.

Thanks

It is a common misconception to think that ASCII and Hex numbers and Decimal numbers are different.
They are not.
They are different visual representations of the *same thing*, used for some presumed human convenience. But a number is a number is a number is a number.
ASCII is just numbers.

Combining two threads. The discussion of midi input from an Arduino device
is just numbers until you attach it to something else. Pitch bend can be
used as a panner if you send the numbers to a panning object.
I once reversed the sense of a sustain pedal in max [ !- 127 ] and jammed it
between the door knob and the frame to make a burglar alarm. I was on tour
when someone stole the key card to my hotel room while I was moving in. I
hooked up all my gear and programmed max to make a very loud noise if the
door was opened while I slept. The pedal would drop and send an pedal down
message to ctlin. Attached that to the switch on a metro. I was very
disappointed when no one came to rob me.
PS. What about Roland octal?

'it's just numbers' is the mantra of my parsons class. i think i
probably say it 30 times a semester.

Double true. It never ceases to amaze me how different the
life of a beginning Max user is if one STARTS with that
and one learns what numbers and symbols and lists and
messages are and then builds from there.
That's probably why someone put those discussions in the "Fundamentals" manual. As the Oblique Strategies say,
Always first steps
