KCS DI/DO not working - LTDU - 03-20-2024
Dear team,
the KCS 2.2.2 is not working for me.
- DI are at random and not changing when making a connection with GND.
- DO can't be switched either.
- Note this is only with the KCS firmware, my own code works fine.
- Maybe it is to be noted that the I2C addresses do not match the standard for my board, as stated here: https://www.kincony.com/forum/showthread.php?tid=2128&pid=6767#pid6767
Please advise.

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

Yes, I am using a KC868-A16 board.

can you try to test with this firmware, this i2c address changed.

Can try i a few days, will come back!
RE: KCS DI/DO not working - admin - 03-22-2024
ok

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

PCF8574 pcf8574_input1(0x3B,4,5); //channel 1-8 old hardware rev: 0x22 hardware rev >1.5: 0x3A
PCF8574 pcf8574_input2(0x39,4,5); //channel 9-16 old hardware rev: 0x21 hardware rev >1.5: 0x39
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?

RE: KCS DI/DO not working - admin - 04-17-2024
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:
