This program consists of the software developed for the ELEC5870M Individual Project. It runs on the mbed LPC1768. It uses the mbed RTOS to perform the following tasks: - Implements intuitive GUI with buttons, LCD TFT Display and LEDs. - Serial Communication with the RPi - I2C communication with INA219 voltage current sensors - Power control at the USB ports

Dependencies:   Adafruit_GFX Adafruit_ST7735 INA219 MODSERIAL MbedJSONValue mbed-rtos mbed
