我把CH376T和MCU采用串口方式通訊，初始化為設(shè)備方式，計算機上顯示為未知USB設(shè)備，程序如下，如何解決？（驅(qū)動為CH372驅(qū)動） UINT8 mInitCH376Device( void ) /* 初始化CH376 */ { UINT8 res; CH376_PORT_INIT( ); /* 接口硬件初始化 */ xWriteCH376Cmd( CMD11_CHECK_EXIST ); /* 測試單片機與CH376之間的通訊接口 */ xWriteCH376Data( 0x65 ); res = xReadCH376Data( ); // xEndCH376Cmd( ); // 異步串口方式不需要 if ( res != 0x9A ) return( ERR_USB_UNKNOWN ); /* 通訊接口不正常,可能原因有:接口連接異常,其它設(shè)備影響(片選不唯一),串口波特率,一直在復(fù)位,晶振不工作 */ #ifdef UART_WORK_BAUDRATE xWriteCH376Cmd( CMD21_SET_BAUDRATE ); /* 設(shè)置串口通訊波特率 */ #if UART_WORK_BAUDRATE >= 6000000/256 xWriteCH376Data( 0x03 ); xWriteCH376Data( 256 - 6000000/UART_WORK_BAUDRATE ); #else xWriteCH376Data( 0x02 ); xWriteCH376Data( 256 - 750000/UART_WORK_BAUDRATE ); #endif SET_WORK_BAUDRATE( ); /* 將單片機切換到正式通訊波特率 */ res = xReadCH376Data( ); // xEndCH376Cmd( ); // 異步串口方式不需要 if ( res != CMD_RET_SUCCESS ) return( ERR_USB_UNKNOWN ); /* 通訊波特率切換失敗,建議通過硬件復(fù)位CH376后重試 */ #endif xWriteCH376Cmd( CMD11_SET_USB_MODE ); /* 設(shè)備USB工作模式 */ xWriteCH376Data( 0x02 ); // mDelayuS( 20 ); // 異步串口方式不需要 res = xReadCH376Data( ); // xEndCH376Cmd( ); // 異步串口方式不需要 if ( res == CMD_RET_SUCCESS ) return( USB_INT_SUCCESS ); else return( ERR_USB_UNKNOWN ); /* 設(shè)置模式錯誤 */ }
測試命令和設(shè)置模式能夠成功么？
后來PC機又能找到了，不知道怎么回事。。。
