The biggest advantage of the logic analyzer, compared with the oscilloprobe, is signal decoding. In short, the signal decoding refers to a series of digital signals of 0 and 1 being interpreted into a convenient data format. But is that all? Zeroplus logic analyzer provide a stronger decoding tool! After decoding the protocol, the edition may be implemented by making reference to bits of the data contents to directly change the digital signal into the human language and accordingly implement automatic adaption in accordance with the user’s requirements.
PCF8574 is the I/0 extension module based on I2C interface. Eight I/0s may be extended with two I/0s, and the circuit diagram is shown below:
