1) Given the file in C, create a new while (1) loop to contain a clear LCD followed by a for loop to print all the ASCII characters from 33 to 123. There should be exactly 0.20 second delay between characters being displayed. Make another one modifies the previous version such that the ASCII characters from 33 to 123 are each printed on the bottom line at column 3, but include the decimal and hexadecimal values of the characters, we can use printf(“%i%x%c”, i, i, i); where i is the loop variable. #include // library containing printf() function #include #include “osc.h” // library for set_osc_32MHz() #include “configureUSART.h” // library for configureUSART(baud) #pragma config WDT = OFF #pragma config OSC = INTIO7 // puts osc/4 on pin 14 to check freq #pragma config MCLRE = OFF #pragma config LVP = OFF #pragma config PBADEN = OFF // PORTB are digital IO void WaitOneSecond(void); void WaitQuarterSecond(void); void main(void) // a C project can only have one main() function { char string[] = ” APSC1299 “; // 16 chars wide to fill bottom line of LCD set_osc_32MHz(); // set MCU to run at 32 MHz // fOSC = 32 000 000 Hz // TOSC = 1/32 000 000 s = 31.25 ns // TCY = 4*TOSC = 125 ns configureUSART(9600ul, 32); // configure MCU serial communication module to run at 9600 baud // with MCU operating at 32 MHz.
