$28)($Embedded Systems$-$ Mixed C & Assembly$)$ Assume you have to design a smart thermostat that is made with an Arm Cortex M$4$ MCU that detects the current temperature of a smart house. If it detects temperature goes below a threshold set by the user, then it levels up the heater and detects temperature goes above the threshold then the MCU levels down the heater. Moreover, users can get the status of the temperature from the thermostat through Bluetooth. Your task is to program the MCU using peripheral protocols to perform these functions. Examples of the protocols are GPIO, Interrupt, GP Timer, RTC$,$ ADC, DAC, $12$C$,$ SPI, UART etc. Write a program in C to implement the system where Level UP and Level Down part of the heater program is required to program in Assembly.
