Hi,  
How can I send a buffer to arduino by the serial port and then transcribe it to a screen? 
Thank you in advance,

[peek~] allows you to get each sample value from a buffer. 

The rest is Arduino stuff I guess, you should look to some Arduino example code probably included in your screen's Arduino library.

Indeed I already use [peek~] but it's the connection with arduino that is the problem...

How can i get a clean list from [peek~] which i can then transcribe to a screen?

Thank you for your reply !

Hi,
Is there a way to retrieve the list from the buffer?


post your problems in some max patch - arduino code etc form

sure it is possible to have a list with buffer contents,

but the size of the buffer would be important factor

Thank you, i will do that. Can you still guide me for the way to have this list please?

check zlmaxsize attribute for zl group as it defaults to 256 max.

if that is less than sample count, then you need something else.

it depends what you want to do with the list.

collect peek~  output into list.
uzing zl.group for example.

maximum is 32767.

Ok thank you ! Now I manage to send the wave to my screen however the serial object on mac OSX is limited to 1024 bytes while on windows it can go up to 4096. Do you know why I can't exceed 1024 on MACOSX?
