Serial not working in max from arduino

Dear all, i am working with Arduino and trying to send serial to max, which works with the Arduino uno.
If i load the same program onto the daisy seed, max seems to have trouble receiving the serial.
I am using a MPR 121 sensor in combination with the board.

Although the right port (serial b 9600) is connected, it somehow does not work.
I would very much appreaciate your help!
Thanks in advance,


This is a library for the MPR121 12-channel Capacitive touch sensor

Designed specifically to work with the MPR121 Breakout in the Adafruit shop

These sensors use I2C communicate, at least 2 pins are required
to interface
