  [arduino code examples for N30]-05 collect N30 all data demo
Posted by: admin - 08-03-2025, 03:27 AM - Forum: N30 - No Replies

Code:
/*
* Made by KinCony IoT: https://www.kincony.com
*
* Demo Program for Reading Data from KinCony N60 Energy Meter (60-channel version)
* via RS485 Modbus using ESP32 and NonBlockingModbusMaster library.
*
* This example:
* - Initializes RS485 Modbus communication
* - Reads current, power, energy, voltage, frequency, temperature, power factor from 6 chips
* - Prints all data to Serial Monitor
* - Uses TaskScheduler to run periodic tasks

  [arduino code examples for N30]-04 Print TEXT on SSD1306 OLED displayer

/*
* Made by KinCony IoT: https://www.kincony.com
*
* This Arduino program demonstrates how to display text on an SSD1306 128x64 OLED display using the U8g2 library.
* The program draws two lines of text on the display:
* - The first line is "KINCONY" in a larger font.
* - The second line is "www.kincony.com" in a smaller font.
*
* The display is connected via I2C (software implementation) with:
* - SCL (clock) on pin IO17
* - SDA (data) on pin IO18
*
* The display's I2C address is set to 0x3C.
