Demonstration Board for MCP2221 I2C
Manufactured By:Microchip
Part Number:ADM00678
The MCP2221 I2C Demo Board creates a USB-to-I2C/UART/RS232 communication bridge between the PC and different devices. With its PC application, it can be used to monitor power consumption of USB devices, ambient temperature variation and external voltage, as well as to measure values for through-hole resistors and capacitors. It also includes an EEPROM, a GPIO expander and a PIC16F1509 pre-programmed microcontroller which can be configured to alert the user in case of specific event types, such as temperature exceeding a certain value.
Features
- Real-time monitoring and logging of the current and power consumptions of a USB device, using the PAC1710 current, voltage and power sensor
- Real-time monitoring and logging of the ambient temperature, using the MCP9808 temperature sensor
- Real-time monitoring and logging of the voltage level recorded by the MCP3221 12-bit analog-to-digital converter
- Performing 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 (when used as digital inputs)
- PIC16F1509 configuration to issue multiple warnings, through an RGB LED, when any of the featured readings are outside user-set conditions (such as “measured USB current is above 50 mA”)
- Storing the above mentioned configuration as well as other, random data in a 24LC128 128-Kbit EEPROM
- Output voltage level control of the MCP4726 digital-to-analog converter
- Creating a USB-to-RS232 bridge; alternately, a USB-to-UART bridge connected to the PIC16F1509 microcontroller.
