示例1: begin

# 或者: from Adafruit_GPIO.I2C import require_repeated_start [as 别名]

Can specify a custom I2C address for the device using the address
parameter (defaults to 0x5A). Optional i2c parameter allows specifying a
custom I2C bus source (defaults to platform's I2C bus).
Returns True if communication with the MPR121 was established, otherwise
