/* * TI's TCS211 L1 does not use standard ARFCNs internally, instead it uses * its own non-standard radio_freq numbers in their place. Other firmware * components and all external interfaces do use standard ARFCNs, thus * conversion functions are invoked at appropriate points in the firmware. * However, L1-internal radio_freq numbers are emitted in L1 debug traces, * thus anyone looking at these traces needs to be able to convert between * standard ARFCNs and L1-internal radio_freq. * * The present utility converts TI's radio_freq numbers as seen in L1 traces * into standard ARFCNs. */ #include <stdio.h> #include <stdlib.h> #include <string.h> #include <strings.h> main(argc, argv) char **argv; { int ti_num; if (argc != 3) { usage: fprintf(stderr, "usage: %s {eu|us} L1_radio_freq\n", argv[0]); exit(1); } ti_num = atoi(argv[2]); if (!strcmp(argv[1], "eu")) ti2arfcn_eu(ti_num); else if (!strcmp(argv[1], "us")) ti2arfcn_us(ti_num); else goto usage; exit(0); } ti2arfcn_eu(radio_freq) { int arfcn; if (radio_freq < 1 || radio_freq > 548) { fprintf(stderr, "error: specified radio_freq is out of range for dual-EU\n"); exit(1); } if (radio_freq < 175) { if (radio_freq <= 124) arfcn = radio_freq; else if (radio_freq < 174) arfcn = radio_freq - 125 + 975; else arfcn = 0; } else arfcn = radio_freq - 175 + 512; printf("%d\n", arfcn); } ti2arfcn_us(radio_freq) { int arfcn; if (radio_freq < 1 || radio_freq > 423) { fprintf(stderr, "error: specified radio_freq is out of range for dual-US\n"); exit(1); } if (radio_freq < 125) arfcn = radio_freq - 1 + 128; else arfcn = radio_freq - 125 + 512; printf("%d\n", arfcn); }
