Modify the provided gpiointerrupt.c code. Your code needs to check the buttons every $200$ms$,$

check the temperature every $500$ms$,$ and update the LED and report to the server every second $($via

the UART$).$ If you push a button, it increases or decreases the temperature set$-$point by $1$ degree

every $200$ms$.$ If the temperature is greater than the set$-$point, the LED should turn off. If the

temperature is less than the set$-$point, the LED should turn on $($the LED controls a heater$).$ You can

simulate a heating or cooling room by putting your finger on the temperature sensor$.$ The output to

the server $($via UART$)$ should be formatted as $.$ This can be broken down as follows:

$$ AA $=$ ASCII decimal value of room temperature $(00-99)$ degrees Celsius

$$ BB $=$ ASCII decimal value of set$-$point temperature $(00-99)$ degrees Celsius

$$ S $=0$ if heat is off, $1$ if heat is on

$$ CCCC $=$ decimal count of seconds since board has been reset
