Low End Microchip PICs C函数

/* GEN_TBLE.C - Borland TurboC
**
** Opens binary file "click.wav" and reads to array and writes to text file
** "wav_dat.c" in the form.
**
** #rom 0x1000 = {0x3c}
** #rom 0x1001 = {0x45}
** etc
**
** Note that the first 100 bytes of the .wav file are discarded as these are setup bytes.
** I am uncertain as to the exact number.
**
** The resulting file may then either be pasted into of included in the CCS C file.
