Modifying a simple Embedded C code with TM4C123G TI microcontroller

I am looking for a freelancer to help me with my project. The skills required are ARM-Cortex-M4, Microcontroller, Embedded C. I am happy to pay a fixed priced. Need help in modifying a simple code with TM4C123G TI microcontroller. I have the code and all the components setup already, It has a temperature sensor to display the temperature on LCD every second, and light sensor to turn on the LED if the room is dark. they work correctly but, I want to make them as interrupts, a one second delay is used for the temperature display and add hibernate mode to wake up the launchpad only when one of the sensors are triggered. the codes are here: [login to view URL] To recap, the temperature sensor is using delay to display on LCD and PuTTY. I want to change it to timer edge trigger interrupt on the same port. the light sensor is just turning on the LED in the while (1) loop, which is not good. I want to change it to interrupt as well with different priority than other interrupt. The hibernate mode as well, needs to be very simple, to wake up the launchpad whenever these interrupts are triggered. if its lagging by few seconds, its expected to come out of hibernate. Also, I need the explanation and commands for your code. Not for very simple line, but for lines that are used to set or clear a bit in a register, as why this bit is set or cleared like this. If you are ok with these, Please let me know. Thanks
