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. ...
Example: mcp.begin_SPI(10, &SPI, 0b101); HW Address recognition must be enabled by enableAddrPins() function.NOTECalling enableAddrPins() will enable IOCON.HAEN bit for all active (CS low) devices on SPI bus.NOTEThere is hardware bug in the MCP23S17 chip, see "MCP23S17 Rev. A Silic...
