I"m a bit new to number manipulation with max.

For a project I work on I need to send 16 bit numbers to the miscorcontroller I"m working with via the serial port. Yet the microcontroller I work with (a very basic one) can recieve through its hardware serial input only bytes (8 bit). So I need to split the 16 bit numbers into 2 halves - for instance - if I want to send the number 500 - or in binary -

Can anyone suggest a way of doing it with max ?

i think this is what you're looking for, not sure :)

yet I"m very new to prgramming with max and dont really know what do to with this block of text that you sent me - do I need to compile it somehow ?

Thanks for that...

just copy all of it, including the "-----begin" etc..., to "-----end", with all the dashes, then in Max 5, choose New From Clipboard. voila! :)

Is there any chance that it will owrk on Max 4.5 ?

Thanks so much...

The patch seejayjames gave you is Max 5 only.

Since it is only a few objects I quickly redid it in Max 4 for you. Exact same patch, just different format. Good luck.

Though this patch works, I'd actually use bitwise operations in this 

case: replace the [/ 256] with [>> 8] and the [% 256] with [& 255]. Both 

are magnitudes faster than / and %. Though this probably doesn't matter 

at all with the speed of recent processors, it is closer to the bitwise
