Pin Mapping for Arduino Timer-Independent Blocks

Simulink^® Support Package for Arduino^® Hardware supports these blocks whose operation is independent of the timer on the Arduino hardware board.

Digital Input	I2C Read	ThingSpeak Write
Digital Output	Serial Receive	WiFi TCP/IP Receive
Analog Input	Serial Transmit	WiFi TCP/IP Send
Analog Output	TCP/IP Receive	WiFi UDP Send
External Interrupt	TCP/IP Send	WiFi UDP Receive
SPI WriteRead	UDP Receive	CAN Transmit
I2C Write	UDP Send	CAN Receive

To view the pin mapping for these blocks, click View pin map in the Block Parameters dialog box. This opens the pin mapping table for Arduino boards and Arduino compatible boards. For example, to find which pins you can use in the ThingSpeak Write block for the Leonardo board, look for the ThingSpeak Write entry under the Blocks column vertically down and Leonardo board horizontally across. Pins 10-13 can be used for the Leonardo board.

For ESP32-WROOM and ESP32-WROVER Arduino compatible boards, use the following pin mapping table to enter the pin numbers for the timer independent blocks in the Simulink model.

For Teensy 4.0 and 4.1 Arduino compatible boards, use the following pin mapping table to enter the pin numbers for the timer independent blocks in the Simulink model.

For Raspberry Pi^® Pico and Pico W Arduino compatible boards, use the following pin mapping table to enter the pin numbers for the timer independent blocks in the Simulink model.

Use the following table to map between the digital and analog pins on an Arduino or Arduino compatible boards.
