[Arduino IDE demo source code for KC868-A16]--#10-KC868-A16_RS485_send and receive

  KC868-A16-RS485.zip (Size: 571.74 KB / Downloads: 1278)
   

I am trying to use this example code

[Arduino IDE demo source code for KC868-A8S]--#08-KC868-A8S_WS2812-RGB_LED_code

but WS2812 is alway off.
PIN 12 is LOW.

I'm wrong, but I can not understand why.

I  test output, input (digital and analog), GSM, and RF433 using my code, everything works fine.

I can't get it to work (tried different code and library) is the RBG WS2812 led on the board only.

I tested my code on RBG WS2812 ring using a ESP32-Wrover-E and it works.

Can someone help me,  please?

Can someone tell me how I can download a demo firmware, when I turn on the board  the first time,  the led changed color.
I want to test the RBG WS2812 LED, so if I have broken it, I'll change with a new one.

Thank, best regards.

Hi~I'm big fan of KINCONY.

I want to communicate with other devices through RS485 of KC868-A16.

I tried various things for this using ESPHOME, but the signal does not come out from the RS485 port of KC868-A16 and the signal is not received either.

Can you give me a simple example of sending and receiving signals via RS485 in KC868-A16?

please please~~~~~!!

The KC868-A32 is used as controller of  light and water leak powered by Esphome.[/url]

Identified deficiencies of the device:
1. Inconvenient connectors for connecting the load, the wires should go parallel to the board.
2. The connector for the signal wires is not removable and it is not convenient. There is no way to quickly dismantle the device without disconnecting the signal wires.
