Use IO I I2C bus timing simulation of the way, the digital signal sent to the chip, through the DA conversion chip, according to the reference voltage, outputs a voltage. The result of DA conversion and then loop through the input pin to connect to AD through I2C read operation, you can read the value of AD conversion.
