大師，
?
???? 目前有個(gè)項(xiàng)目用STC12的單片機(jī)，11.0592晶振，CH376S模塊（網(wǎng)購），USB鍵盤。想通過串口獲取USB鍵盤或USB激光掃描槍的數(shù)據(jù)。使用了論壇的程序，但不成功。
?
論壇里是總線方式，我改了三個(gè)用串口讀寫的函數(shù)。
?
我用串口1與USB通信，用串口2 顯示數(shù)據(jù)
?
? CH376_WR_CMD_PORT( 0x06 );
?
? CH376_WR_DAT_PORT( 0x55 );
?
? s = CH376_RD_DAT_PORT( );
?
?? SerialPortTwo_Send(s);
?
可以正常串口2輸出0AAH
但后續(xù)點(diǎn)擊鍵盤沒有反應(yīng)。
?
是否仍有其他代碼需要修改，才能正常獲取鍵盤數(shù)據(jù)。
?
代碼如下：
