CODE 3 P. Klimo September 2009 /* File: 7SegDisplay_1D.c Description: Displays a digit on single 7-segment display. Segments connected to PORTD ( segment A to RD0, segment B to RD1, etc); Common cathode is connected to the pin RA1 on PORTA. Incremented every 1s. * Test configuration: MCU: P16F877A Dev.Board: EasyPIC4 Xtal: HS, 8 MHz SW: PICC.0 */ #include /* HI-tech compiler definitions */ /* PIC configuration: HS oscillator, Watch Dog Timer off, Browning Effect off, Low Voltage Mode off */ __CONFIG(HS&WDTDIS&PWRTDIS& BORDIS&LVPDIS ); // HiTec Pragmas void Delay_ms(int ms); // Delay routine unsigned short SendCode(unsigned short num); // Convert binary to seven segment code unsigned short count; // Display value void main() { // Initialize Ports PORTA = 0; // Configure bit 1 of Port A as output TRISA = 0xfd; // by clearing bit 1 in the TRISA register PORTD = 0; // Configure all bits of Port D as outputs TRISD = 0; // by clearing the TRISD register do { // Proceed incrementing the displayed digit from 0 to 9 for (count = 0; count0){ for (i=0; i< Xtal_Freq; i++){;} count--; }
