Arduino Internal Pull Up Mode in Simulink

Is there a way to set the pin mode to pull up in Simulink? I see there is a method in MATLAB:

a = arduino('COM4','Uno');
configurePin(a,'D3','pullup');

How would I set this for my Simulink model? Thanks!

I will find someone to help you with this. What are you building?

Hi Hans, Thanks. I am using the Sparkfun CAN BUS shield. The joystick requires pullups. Prior to configuring pins for pull up, you would configure them in Arduino IDE as

pinMode(A1,INPUT);
digitalWrite(A1, HIGH);

This is not an option since you cannot read and write to the same pin at the same time in Simulink.

I created a custom device driver to solve my problem. The block can be found here: Arduino Pinmode Input Pull Up

Excellent. Thank you for sharing!
