基于stm32的语音模块isd1760程序.doc

Isd.h文件/*本函数为语音播放模块。用到函数名是PLAY_NUM(u8 i)；其中i即为想要播放的那一段。注意：初始化时，要初始化两个函数：ISD1760_config();ISD_Init();另外，在函数PLAY_NUM(u8 i)；里面，要根据具体录制修改i的值。用到的端口：PE0(接语音芯片4脚)PE1(接语音芯片5脚)PE2(接语音芯片6脚)PE3(接语音芯片7脚)*/#ifndef _ISD1760_H_#define _ISD1760_H_#include stm32f10x_gpio.hextern uint8_t SR0_L;extern uint8_t SR0_H; extern uint8_t SR1; extern uint8_t ID;extern uint8_t APCL;extern uint8_t APCH;#define RCC_GPIO_ISD1760 RCC_APB2Periph_GPIOE#define MISOGPIO_Pin_0/CPU (IN)#define MOSIGPIO_Pin_1/ISD1760(OUT)#define SCLKGPIO_Pin_2 #define nSSGPIO_Pin_3/语音管脚定义/?SS?,SCLK?,MOSI?#define SCLK_1GPIO_SetBits(GPIO_ISD1760, SCLK)#define SCLK_0GPIO_ResetBits(GPIO_ISD1760, SCLK)#define nSS_1GPIO_SetBits(GPIO_ISD1760, nSS)#define nSS_0GPIO_ResetBits(GPIO_ISD1760, nSS)#define MOSI_1GPIO_SetBits(GPIO_ISD1760, MOSI)#define MOSI_0GPIO_ResetBits(GPIO_ISD1760, MOSI)/?#define PU 0x01 /Power up ?#define STOP 0x02 /?#define RESET 0x03 /?#define CLI_INT 0x04 /?EOM?#define RD_STATUS 0x05 /?#define RD_PLAY_PTR 0x06 /?#define PD 0x07 /Power down ?#define RD_REC_PTR 0x08 /?#define DEVID 0x09 /?ID#define PLAY 0x40 /?#define REC 0x41 /?#define ERASE 0x42 /?#define G_ERASE 0x43 /?#define RD_APC 0x44 /?APC?;APC-?#define WR_APC1 0x45 /?APC1?,?VOL?#define WR_APC2 0x65 /?APC2?,?#define WR_NVCFG 0x46 /?APC?NVCFG;?#define LD_NVCFG 0x47 /?NVCFG?APC#define FWD 0x48 /?#define CHK_MEM 0x49 /?#define EXTCLK 0x4A /?#define SET_PLAY 0x80 /?,?EOM#define SET_REC 0x81 /?,?#define SET_ERASE 0x82 /?#define NOP _nop_() void delayus(void);/15us ?void Delay(uint16_t z );/?:?MS?,Z?MS? uint8_t SPISendData(uint8_t BUF_ISD);/?: SPI?(?)?void RdStatus(void);/?: ?void ClrInt(void);/?: ?void ISD_WR_NVCFG(void);/?: ?void ISD_WR_APC2(void);/?: ?APC2void RdAPC(void);/?: ?APCvoid ISD_Init(void);/?: ? void ISD_CHK_MEM(void);/?: ?void ISD_Reset(void);/?: ?void ISD_Stop(void);/?: ?void ISD_PU(void);/?: ?void ISD_PD(void);/?: ?uint8_t RD_DevID(void);/?: ?ID/void GetToneAdd(uint8_t cNum,uint16_t * ipStartAdd,uint16_t * ipEndAdd);/?: ?void ISD_PLAY(void);/?: ?void ISD_FWD(void);void SetREC(uint8_t cNum);/?: ?void Erase_All(void);/?: ?void ISD1760_config(void);void PLAY_NUM(u8 i);#endifIsd.c文件#include isd.h#include delay.h#define GPIO_ISD1760 GPIOE uint8_t SR0_L;uint8_t SR0_H; uint8_t SR1; uint8_t ID;uint8_t APCL;uint8_t APCH;void delayus(void) u8 i=2; while(i-);void Delay(uint16_t z)uint16_t x,y;for(x=z;x0;x-) /7usfor(y=185;y0;y-);uint8_t SPISendData(uint8_t BUF_ISD) uint8_t i;uint8_t dat = BUF_ISD;SCLK_1;nSS_0;for(i=0;i=1; if(GPIO_ReadInputDataBit(GPIO_ISD1760, MISO) dat|=0x80; SCLK_1; /?delayus(); MOSI_0;/ nSS=1; return(dat); void RdStatus(void) nSS_0;SPISendData(RD_STATUS);SPISendData(0x00); SPISendData(0x00); nSS_1; Delay(10); /?10msnSS_0; SR0_L =SPISendData(RD_STATUS); SR0_H =SPISendData(0x00); SR1 =SPISendData(0x00); nSS_1; Delay(10); void ClrInt(void) nSS_0;SPISendData(CLI_INT);/?EOM?
