SmartLadder is a firmware for Arduino microcontrollers that facilitates the programming of programmable logic controllers (PLCs) using ladder diagrams. It allows users to create ladder programs through a web interface, which generates a string of instructions stored in the microcontroller's memory and continuously read to execute the programmed tasks.

• first: v1.0.0
• v1.0.1
• v1.0.2
• current: v1.0.3

1. Clone this repository or download the ZIP file and extract it to your Arduino libraries folder:

   git clone https://github.com/lucweb/SmartLadderFirmware.git

2. Open the Arduino IDE and go to Sketch -> Include Library -> Add .ZIP Library... and select the SmartLadderFirmware folder.

3. Include the library in your sketch:

   #include <SmartLadderArduino.h>

Here is a basic example of how to use the SmartLadderFirmware library in an Arduino sketch:

#include <SmartLadderArduino.h>

SmartLadderArduino smartLadder;

void setup() {
    smartLadder.setup();
}

void loop() {
    smartLadder.loop();
}

Here is a basic example of how to use the SmartLadderFirmware library in an Arduino sketch:

#include <SmartLadderEsp32.h>

SmartLadderEsp32 smartLadder;

void setup() {
  smartLadder.setup();
}

void loop() {}

By default, Wi-Fi are enabled in the firmware esp32. If you need to modify these settings, or if you want to enable/disable Ethernet (LAN8720) support and I2C, you must configure the config.h file accordingly.

• USE_WIFI: Set to 1 to enable Wi-Fi support, or 0 to disable it.
• USE_I2C: Set to 1 to enable I2C support, or 0 to disable it.
• USE_ETH8720: Set to 1 to enable Ethernet support (LAN8720), or 0 to disable it.

The configuration file config.h should be located in the same directory as your sketch or within the library's directory structure.

Example path:
../documents/Arduino/libraries/SmartLadderFirmware/config.h

Make sure to adjust these definitions to match your hardware setup and project requirements.
