Modify the following code and schematics so that it gives desired outputs mentioned below in the requirements.

A client wanted extra requirements on this thermostat application. He wants the desired temperature Td to be set by a hidden button Sd. Pushing button longer than 5 s shall default Td to 20C, pushing Sd shorter than 2 s shall increment Td by one and flash on internal LED for 1s. Pushing Sd in between 2s to 4s shall decrement Td by one and flash on internal LED for 0.5 s.

1- Prepare the necessary FSM diagram for the described task. Please remember that the time base of the available project was 10ms, and we want to continue with 10 ms period.

2- Assume that you connected a button to pin IO11 with the internal pull-up resistor (i.e., one terminal of the button Sb is grounded to 0V, and the other end is connected to IO11 using a DEFAULT terminal with label IO11). Write the necessary code sections for

i- Additional definition and declaration of variables

ii- Additional setup code for processor and peripherals.

iii- Additional loop code that shall be repeated on runtime.

3- Write a test procedure (i.e. the test code shall be tested by doing this and observing these reactions.)
