to connect an I2s display 20x4) and show DS16B20 sensors on the 
display but I can't do it.

  Serial Monitoring
Posted by: joe.sfeir@gmail.com - 04-30-2025, 03:03 AM - Forum: T16M - No Replies

Hi,

I am using Serial.begin() and Serial.println() but I see nothing in my Serial Monitor (Platformio). What could the problem be?

I am using 115200 as monitoring speed (configured in platformio.ini) and my Serial monitor is configured with the same rate.

I am using the demo code below:

Code:
/*
* Made by KinCony IoT: https://www.kincony.com
*
* This program reads 16 input states from a PCF8575 I/O expander and
* controls a corresponding 16-channel relay module. When an input pin
* is LOW, the corresponding relay is turned ON (LOW means ON for the relay).
* When the input pin is HIGH, the corresponding relay is turned OFF.
*
* Pin Definitions:
* - SDA: GPIO 11
* - SCL: GPIO 12
* - Input I2C Address: 0x24
* - Relay I2C Address: 0x25
*/

#include <Wire.h>        // I2C communication
#include <PCF8575.h>     // Library to control the PCF8575 I/O expander

// Define I2C pins
#define SDA 11           // SDA pin
#define SCL 12           // SCL pin

// I2C addresses
#define INPUT_I2C_ADDRESS 0x24   // I2C address for the input PCF8575 module
#define RELAY_I2C_ADDRESS 0x25   // I2C address for the relay PCF8575 module

PCF8575 pcf8575_IN(INPUT_I2C_ADDRESS);    // Create an object for the input PCF8575
PCF8575 pcf8575_RL(RELAY_I2C_ADDRESS);    // Create an object for the relay PCF8575

void setup() {
  // Initialize I2C communication
  Wire.begin(SDA, SCL);

  // Initialize serial communication
  Serial.begin(115200);

  // Initialize input and relay modules
  pcf8575_IN.begin();
  pcf8575_RL.begin();

  // Turn off all relays at the start
  for (int i = 0; i < 16; i++) {
    pcf8575_RL.write(i, LOW);  // Assuming relays are LOW when OFF, setting all relays to OFF initially
  }

  Serial.println("System started: Input state controlling 16 relays");
}

void loop() {
  uint16_t inputState = 0;

  // Read the state of 16 inputs
  for (int i = 0; i < 16; i++) {
    if (pcf8575_IN.read(i)) {
      inputState |= (1 << i);  // If input is HIGH, set the corresponding bit
    } else {
      inputState &= ~(1 << i); // Otherwise, clear the corresponding bit
    }
  }

  Serial.println("Test Point...");

  // Control the relays based on the input state
  for (int i = 0; i < 16; i++) {
    if (inputState & (1 << i)) {
      pcf8575_RL.write(i, HIGH);  // If input is HIGH, turn the relay OFF
    } else {
      pcf8575_RL.write(i, LOW);   // If input is LOW, turn the relay ON
    }
  }

  // Delay for 500 milliseconds
  delay(500);
}


Thanks

  RF with KCS-firmware
Posted by: jve91 - 04-29-2025, 05:57 PM - Forum: F16 - Replies (1)

Tried to copy some RF-remotes i had laying around.
I go the RF-page and hit the "learn" button. all i got is a timeout.

Is there anything that needs to be done first to receive the RF-signals?
I tried this running v3.9.1.

  Does the KC868-A6 V1.4 board provide a 5V output for DS18B20 sensors?
Posted by: GetBK - 04-29-2025, 12:04 PM - Forum: KC868-A6 - Replies (1)

Hi everyone,
I'm using the Kincony KC868-A6 V1.4 board and planning to connect several DS18B20 temperature sensors. I know these sensors can work with 3.3V, but they tend to be more stable with a 5V power supply—especially when using longer cables.
Does this board provide a dedicated 5V output pin that I can use to power the DS18B20 sensors? If so, where exactly can I find it on the board?
Any help or insights would be greatly appreciated!
Thanks in advance!

  PlatformIO Programming
Posted by: joe.sfeir@gmail.com - 04-29-2025, 10:25 AM - Forum: T16M - Replies (1)

Hi, NooB Here.

Trying to program the ESP32 in PlatformIO:

1. Which ESP32 S3 chip should I configure when creating the project in PlatformIO?

2. How do I make it connect to upload? Do I need to hold a button before uploading? I tried holding the DL button but it didn't connect. Same for the RST button.

Thanks

  Relay type - Can I use DC?
Posted by: polarkreis - 04-28-2025, 05:41 PM - Forum: KC868-A32/A32 Pro - Replies (1)

Can I use 24V DC instead of 230V AC on relays?

I would like to use them to activate my 24VDC activated contactor (and then contactor would let 230V AC to pass through).
