After decades of development, speech recognition and speech coding and decoding technology have become increasingly mature and entered the practical stage. Speech recognition technology has begun to b...
I wrote a small program in Keil uVision3: #include
#define u8 unsigned char
#define u16 unsigned int
#define MSG_MAX_DATA_LENGTH 4
typedef struct MsgObj
{
u8 datalen;
u8 opCode;
u8 date[MSG_MAX_DATA_L...
