The homework is to connect tiva boostxl audio to tiva TM123g4 micro controller. The boostxl audio will record a voice and send it to the micro controller then convert it to frequency domain instead of time domain. The microcontroller will do some processing to measure the frequency and decide if it is a car accident or not. If there is an accident, the micro controller will send a signal to a station to send help. We are planning ti use cellular system to send the signal.
