Firmata, Processing & delayMicroseconds

Hi! :slight_smile:

Here’s my model :
Flash <—> Processing <—> Arduino

Everything works fine, I can turn my led on from a flash button and I can read in flash when I push a button on the arduino board.

I wanted to add a piezo on the board,
arduino.digitalWrite works fine but there’s no arduino.delayMicroseconds function in the Firmata library, therefor I can not play any melody!

If someone already had this problem, or know another library or whatever : Thanks for your help ;D
