Sending strings from render.cpp to pd (libpd)

howlinthurston3

Hi,

I'm trying to send sensor values from an MPR121 to pd with a custom render.cpp file.

I used to do this using heavy but I would like to check out the performance with libpd.

My message with heavy looked like this:
hv_vscheduleMessageForReceiver(gHeavyContext, "sensorValues", 0, "fff", (float)0, (float)i, (float)sensorValue);

where the first float is the board number (for reading 4 boards at a time), the second float is the electrode number and the third float is the actual value.

By using:
libpd_float("sensorValue", (float)sensorValue);

I get 12 lines with a line for every electrode.

My question is: Is there a way to send a string made up of three floats to pd?

Thanks

I found my solution:

	libpd_start_message(3);
	libpd_add_float(0);
	libpd_add_float(i);
	libpd_add_float(sensorValue[i]);
	libpd_finish_list("sensorValue");

Correct, here for more!
