c) Write an endless loop to read the input switches and output the values to the LEDs. Based on the schematics shown on 'LAB2_Schematics.pdf, the four inputs should be port C bits 0 through 3 while the four LEDs should be connected to port A bits 0 through 3. Example: void main() char in; // Use variable 'in' as char TRISA = Ox??; // fill out the ?? with the proper values TRISC = Ox??; // fill out the ?? with the proper values ADCONI = Ox??; // fill out the ?? with the proper values while (1) in = PORTA; // read data from PORTA and save it // into 'in' in = in & OxOF; // Mask out the unused upper four bits PORTC = in; // Output the data to PORTC
