will it run?

[snelweg]

Have bought me a couple of these boards, KinCony KC868-A16:

There is documentation:

https://www.arduino.cc/reference/en/libraries/kc868-arduino-library/
https://www.kincony.com/forum/showthread.php?tid=1666

Question is will it work?

Dang, those are cool! Like Mesa esp32 boards! Alex can comment on compatibility- but these will be supported in the future if they aren’t already

They are cheap too, the board cost me less then if I just bought all the connectors!

looks simple, will try in a few hours.

void setup() {

  Serial.begin(115200);

  delay(3000);

  kc868.begin(115200);//open the kc868  first

  kc868.setReadMode(0);//mode, 0 :default, Query directly; 1: Query all switch state every 2s 

  kc868.setSwitchChangeHook(SwitchUpdate);//set switch change hook

  kc868.setSensorChangeHook(SensorUpdate);//set sensor change hook

  Serial.println("Write Switch 1 on.");
  kc868.writeSwitch(1,1);

  int ret = kc868.readSwitch(1);
  Serial.printf("The state of Switch 1 is %d .\n",ret);

  Serial.println("Delay 1 second.");
  delay(1000);

  Serial.println("Write Switch 1 off.");
  kc868.writeSwitch(1,0);

  ret = kc868.readSwitch(1);
  Serial.printf("The state of Switch 1 is %d .\n",ret);
  

}

oh wow they are cool indeed.

I guess once we know which Pin is which IO we could flash the Arduino firmware onto it easily.

It's not that easy.
The board uses pc8574's to get the large number of in and outputs. So we have to use the kc868.begin(115200);//open the kc868 first driver. But that will work with an edit of your source code.

Or we could do it like this: https://www.kincony.com/forum/showthread.php?tid=1620

There is an API for the board if you use KC868 Arduino library:
