Microchip Technology MCP2221 I2C 演示板

Microchip Technology MCP2221 I²C演示板是探索MCP2221 USB转I2C/UART/SMBus协议转换器功能的完美起点。MCP2221 I²C 演示板允许开发人员使用 MCP2221 器件作为 USB 转 I²C 主转换器（桥）通过 PC 应用程序与 I²C 主器件进行通信。此外，用户可以使用相同的 MCP2221 板创建 USB 转 RS-232 (UART) 桥。

The Microchip Technology MCP2221 I2C Demonstration Board (ADM00678) features a pre-installed MCP2221 in a TSSOP-14 package, along with a PIC16F1509 Microcontroller, and additional support components.

特性

Real-time monitoring and logging:
- Current and power consumption of a USB device, using the PAC1710 current, voltage, and power sensor
- Ambient temperature, using the MCP9808 temperature sensor
- Voltage level recorded by the MCP3221 12-bit analog-to-digital converter
Performs measurements for resistors or capacitors using the MCP2221’s analog-to-digital converter and general purpose input/output pins
Configuration and control of up to 8 GPIOs, available from the MCP23008 I/O expander, as well as continuously monitoring the state of the pins

PIC16F1509 configuration to issue multiple warnings, through an RGB LED, when any of the featured readings are outside user-set conditions
Configuration and other data stored in on-board 24LC128 128-Kbit EEPROM
Output voltage level control of the MCP4726 digital-to-analog converter
Allows creation of USB-to-RS232 bridge
Allows creation of USB-to-UART bridge
