Using C language, pic32 basys mx3 board, please answer questions 5 through 9

5.) Copy the Digilent SSD_Init) function below. What timer is used to control the seven-segment displays and what is the default interrupt time period as noted in the comments? [Note that you don't want to write to the SSDs faster than the refresh interval (interrupt rate) so for stable operation of the SSDs in your program make sure that the update loop takes at least as long as the SSD refresh time.] 6.) Copy the SSD_Timer1Setup() function below. What are the values of TMR_TIME, PB_FRQ, and PR1? [Can you find the mistake in their function code?] 7.) Explain what the following line of code does in the SSD_WriteDigits function. The I= is known as an assignment operator. You may need to look up the syntax for this operation at a site such as(https://www.tutorialspoint.com/cprogramming/c operators.htm) digits [0] |= 0x80 ; 8.) Copy the Digilent SWT_GetGroupValue() function below and explain how the function works. 9.) Find the Interrupt Service Routine (ISR) for the SSDs and copy it below. 5.)
