The data# contained in this file will be used as-is and appended to any contraint file# sharing the same extension generated by the system. Care should be taken not# to have conflicting constraints in PurPer and vendor specific constraint# files. This constraint file must be part of a FPGA project for it to be# used. It will also be used if appropriate on any relevant vendor flow stage# that makes use of such files# /literature/ds/es_cycii.pdfset_global_assignment -name CYCLONEII_M4K_COMPATIBILITY "ON"#set_parameter -name CYCLONEII_SAFE_WRITE "RESTRUCTURE"set_parameter -name CYCLONEII_SAFE_WRITE "VERIFIED_SAFE"#define MAX_LETTERS 27typedef unsigned short WORD;typedef char BYTE;struct morse_code {char ch;BYTE len;WORD code;};extern void get_morse_code (char letter, WORD * code, BYTE * len);/* Binary Counter: -- C Programming Language Example */#include "morse.h"#include <string.h>static void delay (int loops, int scale){for (int j = 0; j<scale; j++){for (int i = 0; i<loops; i++){__asm ("nop");}}}static void beep (unsigned int length){unsigned int i;unsigned char on=P1;for (i=0; i<length; i++){P1 = on & 0xfe;delay(10,1);P1 = on | 1;delay(180, 1);}}static void dash ()P0 = 0xF0;beep (2000);P0 = 0x00;}static void dot (){P0 = 0x0F;beep (400);P0 = 0x00;}static void inter_char_delay () {P0 = 0x00;delay (100, 10000);// delay (100, 10000);// delay (100, 10000);// delay (100, 10000);// delay (100, 10000);// delay (100, 10000);// delay (100, 10000);// delay (100, 10000);// delay (100, 10000);// delay (100, 10000);// delay (100, 10000);// delay (100, 10000);}static void inter_word_delay (){delay (100, 30000);// delay (100, 30000);// delay (100, 30000);// delay (100, 30000);// delay (100, 30000);// delay (100, 30000);// delay (100, 30000);// delay (100, 30000);// delay (100, 30000);// delay (100, 30000);// delay (100, 30000);// delay (100, 30000);}void main (void){BYTE i, len;WORD code;static char __rom message[] = "PURPER NEXAR DEMO";char __rom *p;PSW = 0x00;while (1) {for (p=message; *p; p++) {get_morse_code (*p, &code, &len);for (i=len; i>=0; i--) {if ( (code & (1 << i)) && (code & (1 << (i-1)))){ dash ();i--;} else if (code & (1 << i)) {dot ();}else {inter_char_delay ();}}}inter_word_delay ();}}1.5morse.c#include "morse.h"#define SPACE (MAX_LETTERS-1)static struct morse_code __rom morse_map [MAX_LETTERS] = { {'A', 4, 0x000B},{'B', 8, 0x00D5},{'C', 9, 0x01AD},{'D', 6, 0x0035},{'E', 1, 0x0001},{'F', 8, 0x00AD},{'G', 7, 0x006D},{'H', 7, 0x0055},{'I', 3, 0x0005},{'J', 10, 0x02DB},{'K', 7, 0x006B},{'L', 8, 0x00B5},{'M', 5, 0x001B},{'N', 4, 0x000B},{'O', 8, 0x00DB},{'P', 9, 0x016D},{'Q', 10, 0x036B},{'R', 6, 0x002D},{'S', 5, 0x0015},{'T', 2, 0x0003},{'U', 6, 0x002B},{'V', 8, 0x00AB},{'W', 7, 0x005B},{'X', 9, 0x01AB},{'Y', 10, 0x035B},{'Z', 9, 0x01B5},{' ', 2, 0x0000}};void get_morse_code (char letter, WORD * code, BYTE * len) {if ((letter>='A')&&(letter<='Z')) {*code = morse_map[letter-'A'].code;*len = morse_map[letter-'A'].len;} else {*code = morse_map[SPACE].code;*len = morse_map[SPACE].len;}}。
