This Arduino MCP23017 Interrupt Example code shows you exactly how to use and connect an external interrupt pin and make interrupts work correctly. As you saw in the previous example - you can not just use the Arduino template code because there is a subtle problem involved. This example expla...
Arduino nano ESP32 as board: Thank you! Here are the compilation results using ESP32 S3 Dev Module and Arduino nano ESP32 as board. I used the example code Adafruit MCP23017 Arduino Library (mcp23xxx)blink). ESP32 S3 Dev Module as board: (compilation OK) ...

Unlike most Arduino library, no default instance is created when the library is included. It's up to you to create one using the appropriate I2C address based on MCP23017A0,A1andA2pins wirings. Available addresses go from0x20to0x27, allowing up to 8 MCP23017 on the same I2C bus. ...
Adafruit even has an Arduino library with example code written which will set pin state, read and write from individual pins, and set the pullups. Item SpecificsThis board/chip uses I2C 7-bit address between 0x20-0x27, selectable with jumpers Add another 16 pins to your microcontroll...

Copy Code pin0.value = True # GPIO0 / GPIOA0 to high logic level pin0.value = False # GPIO0 / GPIOA0 to low logic level You can also set a pin as an input, again using the same functions and properties as the DigitalInOut class. For example here's how to create GPIO1 / ...
I used the example code Adafruit MCP23017 Arduino Library (mcp23xxx)blink). ESP32 S3 Dev Module as board: (compilation OK) Sketch uses 287321 bytes (21%) of program storage space. Maximum is 1310720 bytes. Global variables use 20304 bytes (6%) of dynamic memory, leaving 307376 bytes for...
To install, use the Arduino IDE Library Manager. Pin Addressing When using single pin operations such aspinMode(pinId, dir)ordigitalRead(pinId)ordigitalWrite(pinId, val)then the pins are addressed using the ID's below. For example, for set the mode ofGPB0then usepinMode(8, ...).NOTE...
The rationale is that the programming environment of the Arduino ESP32 S3 board uses a remapping by means of the include file io_pin_remap.h. This file remaps the pins of several core Arduino functions. The remapping is implemented by #define macros and these implement "hard" text ...
