* Description:
* This Arduino program reads analog values from four analog input pins (A1, A2, A3, A4)

* GPIO pins and the program reads the voltage levels from these pins every 2 seconds.

* Pin Definitions:
* - A1: GPIO 7
* - A2: GPIO 6
* - A3: GPIO 5
* - A4: GPIO 4

  [arduino code examples for A32 Pro]-02 Read digital input ports state
Posted by: admin - 09-13-2024, 11:44 PM - Forum: KC868-A32/A32 Pro - No Replies

Code:
/*
  Made by KinCony IoT: https://www.kincony.com

  Program functionality:
  This program uses an ESP32-S3 to read inputs from two XL9535 I/O expander chips
  (with I2C addresses 0x24 and 0x25) and one PCF8574 I/O expander (with I2C address 0x23) via I2C.
  The XL9535 chips handle 1-32 channels, while the PCF8574 chip handles channels 33-40.
  The program reads the state of all these inputs and prints them in binary format to the serial monitor.

  Key points:
  - The I2C bus is initialized on GPIO pins 11 (SDA) and 10 (SCL) with a frequency of 40kHz.
  - The XL9535 chips read the state of input pins for channels 1-32.
  - The PCF8574 chip reads the state of input pins for channels 33-40.
  - The state of the inputs is printed to the serial monitor in binary format every second.

  communication with I2C sensor
Posted by: remiasz - 09-13-2024, 01:47 PM - Forum: KC868-A series and Uair Smart Controller - Replies (3)

Does the KCS firmware allow communication with sensors connected to the I2C port? 
How?

  Get PWM out, even by sacrificing other functionality
Posted by: tarajas - 09-12-2024, 09:50 PM - Forum: KC868-A4 - Replies (7)

Hi,

I have a 1.2.4 version A4 board and I was wondering if there are some quick and dirty adjustments to be made potentially even with some small amount of soldering to get a PWM output on the board maybe?

Like I could sacrifice the 433MHz related functionality for examle?

Is there maybe such a modification?

Thanks for the help in advance

  AIO board has failed
Posted by: telewizard13 - 09-12-2024, 09:06 PM - Forum: KC868-AIO - Replies (8)

My 3 month old KC868-AIO board has failed. It no longer communicates with my Home Assistant over ethernet, doesn't appear on WIFI.  Can't connect via USB and the ESP chip on the board is VERY hot. There is no activity on the ethernet connector. Not sure what failed or why, because it was working perfectly even earlier today. The power supply is fine and measures 12.45 volts and the power LEDs are lit, but it appears to be brain dead. I powered it down and disconnected all the I/O plugs and there was no change.

buen día , ya resolví lo del teclado wiegand, ahora el problema fue que al meter ese codigo como tengo la entrada digital 1 configurada para si la pongo a gnd se activa el rele 2 ahora se activa solo porque pasa eso ? Si antes no pasaba eso envío foto del teclado wiegand conectado y los cables amarillos son el botón simulado de la entrada P0

  KC868-A8 V1.5 PCF8574
Posted by: GVDC - 09-11-2024, 11:07 AM - Forum: KC868-A8 - No Replies

Hello, I am only a beginner and have problems with interrupt.
I have KC868-A8 V1.5 and use PCF8574. 
The program runs OK, but for the security of the project I need to watch that 1 parameter measured with an analog tool,  stops the whole sketch at avery moment when the parameter is to high.
Is it possible with my Kincony?
Can somebody help with the code? 
Which version on the IDE do I need? 

Kind regards
