Simulink Arduino The following Arduino pins are used with the Arduino IDE. All pins do not use the same pin space. There can be more than one connector for each pin, but this is to avoid conflicting in certain Arduino pins as well (for example, on the I2C and SPI pins). Please remember to use one of the following 3 pins: GPIO +1, GPIO –1, and I2C +2, with one or more other pins in the same direction. Use a digital pin for pin 1 to make the data transfer even when the pin is separated. Set up a SPM port. The SPM port has no need to be connected to the Arduino core (you can switch with a 4mm pin as long as the CPU is running on a VGA interface).
