Fix for #47 MCP23S17, bug in enable interrupt handling. Pre 0.8.0 versions are obsolete.0.6.0 Breaking changeThe version 0.6.0 has breaking changes in the interface. The rationale is that the programming environment of the Arduino ESP32 S3 board uses a remapping by means of the include ...

A minimal example that shows catching missed interrupts: PCF8574_interrupt_advanced.ino 0.4.0 Breaking change Version 0.4.0 introduced a breaking change. You cannot set the pins inbegin()any more. This reduces the dependency of processor dependent Wire implementations. The user has to callWire.be...

The test program is virtually identical to the MCP23017 I2C example: You need to load the SPI kernel modules before you can use SPI devices. Use the gpio command: gpio load spi The MCP23s08 and MCP23s17 only have internal pull-up resistors, not pull-down. ...
