Please tell me how to view the MWC info with arduino IDE 'serial monitor' ?

Hi, everyonw :P I really want add "Serial.println(..." in multiwiicopter codes. But mwc had own "Serial", so you can't use "Serial.println". Now i download mwc2.2 and found some comment, looks just open "#define LCD_TTY" then you can use arduino IDE's serial monitor to view the info. But, i try it and haven't any info display on serial monitor! =( please check clips from config.h:

* If you are without a DISPLAYD then You may enable LCD_TTY and
     * use arduino IDE's serial monitor to view the info.
 #define LCD_TTY         // SERIAL LCD: useful to tweak parameters over cable with arduino IDE 'serial monitor'

please tell me why serial monitor isn't work, i just print info on 'serial monitor. :astonished: thank you XD

Post ALL your code. What you posted doesn't show you writing to the serial monitor. We're not mind readers.

Is the MWC connected to pins 1 and 0 on the Arduino?

If so, why aren't you using SoftwareSerial on some other pins to talk to the MWC?
