Does anyone have an experience getting the Radio Shark 2 set up? I'm hoping to use it for radio streaming in my apartment.
I've found shark2.c on the net and gcc is failing to compile it; I'm a PHP developer with a lot of admin time on FreeBSD (8-RELEASE, AMD64 build presently) but can't get my head around that piece. r...@server /usr/local/include]# gcc -g -o shark2 -lhid shark2.c In file included from shark2.c:21: /usr/include/hid.h:6:23: error: hidparser.h: No such file or directory In file included from shark2.c:21: /usr/include/hid.h:69: error: expected specifier-qualifier-list before 'HIDData' shark2.c: In function 'main': shark2.c:98: warning: incompatible implicit declaration of built-in function 'exit' shark2.c:102: warning: incompatible implicit declaration of built-in function 'exit' [[Basically it's not finding hidparser.h - I get that - but it isn't checking paths to look for it or I just can't seem to set any new search paths -R]] ::::::: contents of shark2.c ::::::: /* This souce code written my Michael Rolig (email: michael_ro...@alumni.macalester.edu) * This can be considered to be in the public domain */ /* Modified for Radio Shark2 2007-05-11 * This souce code written my Hisaaki Shibata (email: shib...@luky.org) * This can be considered to be in the public domain */ #define DEBUG false /* Set true for copious debugging output */ #define SHARK_VENDID 0x077d /* Griffin's Vendor ID */ #define SHARK_DEVID 0x627a /* The radioSHARK's Device ID */ #define READ_EP 0x5 /* libhid read command? */ #define WRITE_EP 0x5 /* libhid write command? */ #define SEND_PACKET_LENGTH 7 /* size of an instruction packet: shark2=7 */ #include </usr/include/stdio.h> #include </usr/include/string.h> #include </usr/include/unistd.h> #include </usr/include/hid.h> void usage(int argc, const char** argv) { printf("%s <command> <arg>\n\tchange state of radioSHARK\n\n", argv[0]); printf("commands:\n" " -fm <freqeuncy> : set FM frequency, e.g. '-fm 91.5'\n" " -am <frequency> : set AM frequency, e.g. '-am 730'\n" " -blue <intensity> : turn on blue LED (0-127) '-blue 127'\n" " -red <0/1> : turn on/off red LED '-red 1'\n"); } int main(int argc, const char** argv) { /* Declare variables used later */ hid_return ret; HIDInterface* hid; HIDInterfaceMatcher matcher = { SHARK_VENDID, SHARK_DEVID, NULL, NULL, 0 }; /* Build the instruction packet to send to the shark */ unsigned char PACKET[SEND_PACKET_LENGTH] = { 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00 }; unsigned short encodedFreq; float freq; unsigned int intensity; if (argc == 3) { if (strcmp(argv[1], "-fm") == 0) { /* Tune to an FM frequency */ PACKET[0] = 0x81; encodedFreq = 0; freq = atof(argv[2]); encodedFreq = ((freq * 10 * 2) - 3 ); PACKET[1] = (encodedFreq >> 8) & 0xFF; PACKET[2] = encodedFreq & 0xFF; PACKET[3] = 0x33; PACKET[4] = 0x04; PACKET[5] = 0x00; PACKET[6] = 0x28; if (DEBUG) { printf("band = fm\n"); printf("freq = %.1f\n", freq); printf("encoded freq = 0x%x\n", (unsigned int)encodedFreq); } } else if (strcmp(argv[1], "-am") == 0) { /* Tune to an AM frequency */ PACKET[0] = 0x81; encodedFreq = 0; freq = (float)atoi(argv[2]); encodedFreq = ((unsigned short)freq * 4 ) + 16300; PACKET[1] = (encodedFreq >> 8) & 0xFF; PACKET[2] = encodedFreq & 0xFF; PACKET[3] = 0xF3; PACKET[4] = 0x36; PACKET[5] = 0x00; PACKET[6] = 0x24; if (DEBUG) { printf("band = am\n"); printf("freq = %d\n", (unsigned int)freq); printf("encoded freq = 0x%x\n", (unsigned int)encodedFreq); } } else if (strcmp(argv[1], "-blue") == 0) { /* Adjust the blue LED */ intensity = atoi(argv[2]); PACKET[0] = 0x83; PACKET[1] = (char)intensity; } else if (strcmp(argv[1], "-bblue") == 0) { /* Adjust the blue LED's pulsing rate */ intensity = atoi(argv[2]); PACKET[0] = 0xA1; PACKET[1] = (char)intensity; } else if (strcmp(argv[1], "-red") == 0) { /* Toggle the red LED */ intensity = atoi(argv[2]); if (intensity) PACKET[0] = 0x84; else PACKET[0] = 0x84; PACKET[1] = (char)intensity; } else { /* Bad command - display the program's usage instructions */ usage(argc, argv); exit(1); } } else { usage(argc, argv); exit(1); } /* Turn libhid debugging on if requested.
