1.Description:
What can MCP2221 chip do? This chip is similar to a USB to serial converter chip, but also adds GPIO and I2C interfaces. The analog/digital GPIO pin can serve as a 10 bit analog input (ADC), and even a 5-bit DAC output. The I2C interface is very suitable for communicating with OLEDs, sensors, and PWM drivers, and it is the most popular interface for small devices. You can use GPIO to perform operations such as LED flashing, reading switches or buttons, etc
