I bought the uLCD-32PTU (https://www.sparkfun.com/products/11677?
) and it worked fine using it as a slave with Aduino uno R3 and mega 2560, but I have problems with the Arduino due. I explain: I first loaded the Serial Library for the Picaso (https://github.com/4dsystems/Picaso-Serial-Arduino-Library
) to Aduino's library folder then loaded this code to an arduino uno:
#define DisplaySerial Serial
Display.TimeLimit4D = 5000 ;
Display.putstr("Hello World\n") ;
Then connected power, ground RX and TX to the arduino uno, it worked fine (see pictures 1 and 2).
Then I connected and Arduino mega uploaded the same code and it worked fine.
Then I connected an Arduino due uploaded the same code, but there is problem, there are no serial communication on the Serial port and no display on the LCD screen. I am wondering if there is a problem bettween the Serial library for the Picaso and the Arduino due... (I hope I did not make a stupid mistake, pictures 3 and 4 might help).
Thank you in advance for your help.
