The Module Sim a7680c can be easily programmed using an Arduino UNO. Below is an example code snippet to simulate a simple analog signal:

// Include necessary libraries
#include <Wire.h>  // For I2C communication
#include <SPI.h>   // For SPI communication

// Define pin connections
#define ANALOG_IN A0  // Analog input pin
#define DIGITAL_IO 7  // Digital I/O pin

void setup() {
  // Initialize serial communication for debugging
  Serial.begin(9600);

  // Configure pins
  pinMode(ANALOG_IN, INPUT);  // Set analog pin as input
  pinMode(DIGITAL_IO, OUTPUT); // Set digital pin as output

  // Print initialization message
  Serial.println("Module Sim a7680c Initialized");
}

void loop() {
  // Read analog value from the input pin
  int analogValue = analogRead(ANALOG_IN);

  // Print the analog value to the serial monitor
  Serial.print("Analog Value: ");
  Serial.println(analogValue);

  // Simulate a digital output based on the analog value
  if (analogValue > 512) {
    digitalWrite(DIGITAL_IO, HIGH);  // Set digital pin HIGH
  } else {
    digitalWrite(DIGITAL_IO, LOW);   // Set digital pin LOW
  }

  // Add a small delay for stability
  delay(100);
}
