Write an assembly program that turn LED on as soon as the ambient air relative humidity gets over $80\%$ and turns it off when it gets below $75\%.$ For humidity between those marks the LED state must not be modified from previously set value. Print current humidity value to the terminal with $100$ms period handled by LETIMER$0.$ Make sure to handle LETIMER$0$ event in NVIC.

Hint: think on implementing FSM $($Finite State Machine$)$ for changing the LED states.

do it following this:

INCLUDE EFR$32$BG$22.$inc ; CPU register definitions

INCLUDE terminal.inc ; terminal function definitions

EXPORT main

IMPORT LETIMER$\_$setup ; import names from other code files

IMPORT GPIO$\_$setup
