a. (1 pts.) If a motor takes 90 steps to make one complete revolution, what is the step angle for this motor? b. (1 pts.) Calculate the number of steps per revolution for a step angle of 7.5 degrees. c. (2 pts.) What is the baud rate if we use UBRR =15 to program the baud rate? Assume XTAL=10MHz d. (3 pts.) For XTAL =10MHz, find the UBRR value (in both decimal and hex) for each of the following baud rates. i. 9600 ii. 4800 iii. 1200 e. (8 pts.) Find the UBRR and the baud rate error for the following baud rates if XTAL = 11.0592 MHz and U2X=0. i. 9600 ii. 19200 iii. 38400 iv. 57600
