To play 8 bit sample size in addition to original 16 bit 3. To be more fault tolerant when playing wav files. */ #ifndef WAVPLAYER_H #define WAVPLAYER_H #include "mbed.h" #define SAMPLE_FREQ 40000 #define BUF_SIZE (SAMPLE_FREQ/10) #define SLICE_BUF_SIZE 1 typedef struct uFMT_STRUCT { short comp_code; short num_channels; unsigned sample_rate; unsigned avg_Bps; short block_align; short sig_bps; } FMT_STRUCT; class WavPlayer { public: void play_wave(char *wavname); private: void cleanup(char *); void fill_adc_buf(short *, unsigned); void swapword(unsigned *); // a FIFO for the DAC short DAC_fifo[256]; short DAC_wptr; short DAC_rptr; short DAC_on; void dac_out(); }; #endif
