daisy::Mcp23017Transport Class Reference

Detailed Description

Barebones driver for MCP23017 I2C 16-Bit I/O Expander For now it supports only polling approach.

Usage: Mcp23017 mcp; mcp.Init(); mcp.PortMode(MCP23017Port::A, 0xFF); // Inputs mcp.PortMode(MCP23017Port::B, 0xFF); mcp.Read(); mcp.GetPin(2);
