Im using MSP$-$EXP$430$FR$5994$ and the LaunchPadBOOSTXL$-$EDUMKII with Code Composier Studio. Im haveing trouble getting the Piezo buzzer working, right now im getting nothing from the buzzer, it should complete these two objectives:

$6.$ Configure the ADC results from either the vertical or horizontal joystick positions to create a variable PWM signalfrom a compare mode timer output that outputs to buzzer. Observe the effects of the joystick on the volume

$7.$ Modify the code in step $6$ to use the joystick to vary the tone $($i$.$e$.,$ frequency$)$ of the buzzer as well as the volume.

Currently the code changes the RGB collor depending on the joystick postion, with the changes need to be made is making the buzzer work.

My Current Code:

#include

#include

#define JOYSTICk$\_$THRESHOLD $2000$

#define MAX$\_$FREQUENCY $10000//$ Maximum frequency of the buzzer

#define MIN$\_$FREQUENCY $1000//$ Minimum frequency of the buzzer

#define MAX$\_$VOLUME $1000//$ Maximum volume $($duty cycle$)$ of the buzzer
