// Example code to interface MSPM0G3507 with Arduino UNO via I2C

#include <Wire.h>

#define MSPM0G3507_ADDRESS 0x48 // I2C address of MSPM0G3507

void setup() {
  Wire.begin(); // Initialize I2C communication
  Serial.begin(9600); // Initialize serial communication
}

void loop() {
  Wire.beginTransmission(MSPM0G3507_ADDRESS); // Start I2C transmission
  Wire.write(0x00); // Send command to read data
  Wire.endTransmission(); // End I2C transmission

  Wire.requestFrom(MSPM0G3507_ADDRESS, 2); // Request 2 bytes from MSPM0G3507

  if (Wire.available() == 2) { // If 2 bytes are received
    int data = Wire.read() << 8 | Wire.read(); // Combine the two bytes
    Serial.println(data); // Print the received data
  }

  delay(1000); // Wait for 1 second
}

1. Microcontroller Not Powering Up:

   • Solution: Check the power supply voltage and ensure it is within the specified range (1.8V to 3.6V). Verify all power and ground connections.

2. GPIO Pins Not Responding:

   • Solution: Ensure the GPIO pins are correctly configured as input or output in the firmware. Check for any short circuits or incorrect connections.

3. ADC Not Reading Correct Values:

   • Solution: Verify the analog signal connections and ensure the ADC settings in the firmware are correct. Use proper filtering and shielding for the analog signals.

4. Communication Interface Not Working:

   • Solution: Check the connections for I2C, SPI, or UART interfaces. Ensure the correct settings (baud rate, clock speed, etc.) are configured in the firmware.

• Use Debugging Tools: Utilize debugging tools such as oscilloscopes and logic analyzers to monitor signals and diagnose issues.
• Check Firmware: Ensure the firmware is correctly written and uploaded to the microcontroller. Use TI's development tools for efficient debugging.
• Consult Datasheet: Refer to the MSPM0G3507 datasheet for detailed information on pin configurations, electrical characteristics, and usage guidelines.
