我的CH376S初始化正常，U盤的連接和斷開也正常，但在連接之后，向CH376S發(fā)出CMD_DISK_MOUNT命令后，收到status值為0X22,資料上沒有這個(gè)值，不知怎么處理，請(qǐng)指教，謝謝！ 我的中斷程序如下：
void ch376_int_trans() { unsigned char status,i,len; ch376_begin(); ch376_write_byte(CMD01_GET_STATUS); status = ch376_read_byte(); ch376_end(); sprintf(str,"ch376 status:[%d][0x%2x] ",status,status); rs485_write_str(str); switch(status) { case USB_INT_USB_SUSPEND: rs485_write_str((unsigned char*)"usb suspend\x0d\x0a"); break; case USB_INT_WAKE_UP: rs485_write_str((unsigned char*)"usb wake up\x0d\x0a"); break; case USB_INT_EP2_OUT: //端點(diǎn)2下傳成功中斷 rs485_write_str((unsigned char*)"usb ep2 out\x0d\x0a"); break; case USB_INT_EP1_OUT: //端點(diǎn)1下傳成功中斷 rs485_write_str((unsigned char*)"usb ep1 out\x0d\x0a"); break; case USB_INT_EP1_IN: //端點(diǎn)1上傳成功中斷 rs485_write_str((unsigned char*)"usb ep1 in\x0d\x0a"); break; case USB_INT_EP2_IN: //端點(diǎn)2上傳成功中斷 rs485_write_str((unsigned char*)"usb ep2 in\x0d\x0a"); break; case USB_INT_SUCCESS: rs485_write_str((unsigned char*)"usb success\x0d\x0a"); break; case USB_INT_CONNECT: rs485_write_str((unsigned char*)"usb connect\x0d\x0a"); ch376_status.connected = 1; PostMessage(&msg_ch376_disk_mount); break; case USB_INT_DISCONNECT: rs485_write_str((unsigned char*)"usb disconnect\x0d\x0a"); ch376_status.connected = 0; break; case USB_INT_BUF_OVER: rs485_write_str((unsigned char*)"usb buf over\x0d\x0a"); break; case USB_INT_USB_READY: rs485_write_str((unsigned char*)"usb ready\x0d\x0a"); break; case USB_INT_DISK_READ: rs485_write_str((unsigned char*)"usb disk read\x0d\x0a"); break; case USB_INT_DISK_WRITE: rs485_write_str((unsigned char*)"usb disk write\x0d\x0a"); break; case USB_INT_DISK_ERR: rs485_write_str((unsigned char*)"usb disk error\x0d\x0a"); break; default: rs485_write_str((unsigned char*)"unknown state\x0d\x0a"); break; } }
