I have the "152" on my Due.
The TFT touch controller is the STMPE610 which has horrible documentation and I can't find anything to let me know. Adafruit sends you to one of their 2.8TFT screens for info on the Touch controller and in there it states there are 10K resistors on the SDA/SCL so I'm guessing it is there on the breakout of the STMPE610 that I'm using.
I have tried to use the internal pullups on the Due SDA/SCL by calling pinMode(20, INPUT_PULLUP) and the corresponding call for PIN 21 also but it didn't help.
