This lab expands on the descriptor code developed in Lab 1.
1. Create a new project “Project Lab 2”, and build the framework as per procedure
2. Ensure that the Project Build Options are configured as was done in Lab 1 steps
3. In the Project window open the mouse.c source file.
4. Scroll down to find the variable definitions and uncomment the variables and
5. Scroll down to the private prototype section and uncomment the user function
6. Scroll down to the UserInit(). It is here that all components pertinent to the
7. Scroll down to the ProcessIO() function. Note the push button check that
8. Finally, scroll down to the Emulate_Mouse function and insert the code in
/**VARIABLES*****************************/
a) BYTE old_sw2,old_sw3;
c) BYTE movement_length;
