pcf8575 is a 16-bit expansion chip, available in the Arduino library, it can address up to 8 chips, which means a total of 8 * 16 128 pin control, which is an essential issue for ESP.
for example
M64P0.1
Set the 1st pin of the 0th IC in the I2C port to 1.
M65P0.1
Set the 1st pin of the 0th IC in the I2C port to 0.
example
M66P0.1
he. wait until pin 1 of the chip becomes 1

In this way, we have a total of 128 pins that can be used as input and output.
