This project demonstrates the implementation of Arm® TrustZone® technology on the PIC32CK SG01 MCU using the MPLAB® Harmony v3 software framework. TrustZone technology enables secure and non-secure code to run on a single MCU, ensuring security isolation between trusted and non-trusted resources while maintaining system performance.

Developed on the PIC32CK SG01 Curiosity Ultra Development Board with the I/O1 Xplained Pro Extension Kit, the application consists of Secure and Non-secure modes that work together to manage LED control and temperature monitoring while ensuring secure data handling through Non-Secure Callables (NSC).

Key Features:
Secure mode application: Manages LED toggling, reads temperature data, writes/reads EEPROM, and handles security-sensitive operations.

Non-secure mode application: Requests temperature data, retrieves stored values from EEPROM, and prints outputs on a serial console.

Switch-controlled functionalities:

SW0: Changes LED toggling or temperature sampling rates.

SW1: Toggles between Basic and Extended functionalities.

Functionality:
🔹 Basic Mode: Secure mode toggles LED0 at predefined intervals and shares the toggling rate with the Non-secure mode via NSC.
🔹 Extended Mode: Secure mode reads temperature data every 500ms and stores it in EEPROM. The Non-secure mode requests and displays this data on a serial console.
🔹 Users can retrieve the last five stored temperature values from EEPROM upon request.
🔹 LED indicators: Green LED (LED0) toggles on temperature display requests, while Red LED (LED1) toggles when temperature values are read from EEPROM.

🔹Peripherals & Tools Used:
Secure Mode: Secure PORT, SERCOM (I²C), RTC, Secure EIC (External Interrupt Controller)

🔹Non-secure Mode: USART, DMA, Non-secure PORT (USART Pins)

🔹Software Tools: MPLAB Harmony v3, MPLAB X IDE

This project highlights the capabilities of TrustZone® technology for secure embedded application development, ensuring robust security isolation while maintaining efficient data communication between Secure and Non-secure modes. 

Arm® TrustZone® Technology Getting Started Application on PIC32CK SG01 (Cortex®-M33) MCUs

This project demonstrates a low-power embedded application for the PIC32CM LE00 MCU, developed using MPLAB Harmony v3. It optimizes power consumption by utilizing different Sleep modes (Idle and Standby) and leveraging SleepWalking technology to allow peripherals to operate efficiently without waking up the CPU.

Key Features:
Standby and Idle Sleep modes implemented for power optimization

Power Manager (PM) module configured to control Low Power modes

SleepWalking utilized for efficient peripheral wake-up without CPU intervention

Developed on PIC32CM LE00 Curiosity Pro Evaluation Kit with I/O1 Xplained Pro Extension Kit

Functionality:
On power-up, a menu is printed on a PC serial terminal to select power measurement modes

Power consumption is measured in Standby and Idle Sleep modes using Data Visualizer

The device wakes up when:

The light sensor is covered (triggers ADC sampling)

The SW1 switch is pressed (toggles between Standby and Idle modes)

Room temperature is printed on a serial terminal upon wake-up

EVSYS (Event System) integration enables peripheral-to-peripheral communication, reducing CPU intervention

Peripherals & Tools Used:
Peripherals: I²C (SERCOM5), RTC, USART (SERCOM3), ADC, PORT, PM, EIC, EVSYS

Software Tools: MPLAB Harmony v3, MPLAB X IDE, Data Visualizer

This project showcases an efficient low-power design on a 32-bit ARM Cortex-M23 MCU, minimizing energy consumption while maintaining seamless peripheral operation.
