KCS firmware only use for KinCony's ESP32 board, not for every other PCB.

The outputs are working now with the modified version, but the inputs (all shown OFF) are not recognized.
With my code in contrast everything works (but I want to use KCS!):
//Set i2c INPUT address
PCF8574 pcf8574_input1(0x3B,4,5); //channel 1-8 old hardware rev: 0x22 hardware rev >1.5: 0x3A <---- IS DIFFERENT!!!
PCF8574 pcf8574_input2(0x39,4,5); //channel 9-16 old hardware rev: 0x21 hardware rev >1.5: 0x39
//Set i2c OUTPUT address
PCF8574 pcf8574_output1(0x3C,4,5); //channel 1-8 old hardware rev: 0x24 hardware rev >1.5: 0x3C
PCF8574 pcf8574_output2(0x3D,4,5); //channel 9-16 old hardware rev: 0x25 hardware rev >1.5: 0x3D

address 0x3A and 0x39 for INPUT ports can work well , right?

list all your correct i2c address of OUTPUT and INPUT:
PCF8574 pcf8574_input1(xxxx,4,5); //channel 1-8 old hardware rev: 0x22 hardware rev >1.5:
PCF8574 pcf8574_input2(xxxx,4,5); //channel 9-16 old hardware rev: 0x21 hardware rev >1.5:
PCF8574 pcf8574_output1(xxxx,4,5); //channel 1-8 old hardware rev: 0x24 hardware rev >1.5:
PCF8574 pcf8574_output2(xxxx,4,5); //channel 9-16 old hardware rev: 0x25 hardware rev >1.5:
