MCP23X17评估板主要用于接口，GPIO 扩展器。主要属性有16 位 GPIO 扩展器，I2C 和 SPI。Devices Supported: MCP23017, MCP23S17Summary Description:The MCP23X17 16-bit GPIO Expander Evaluation Board demonstrates simple input/output functionality of the MCP23017 (I2C interface) and the MCP23S17 (SPI interface). The system demonstrates the simplicity of monitoring four pins configured as inputs and applying a predetermined pattern on LEDs connected to the remaining 12 pins configured as outputs.Features:
Demonstrates the MCP23X17 devices in a simple I/O application
ICSP header for the PICmicro allows users to customize firmware to further evaluate the MCP23X17
Jumpers and headers allow the MCP23X17 to connect directly to custom applications for prototype work
Can be powered from a 3.0V to 5V DC power source (connected to the +5V and GND test points)
