从朋友那寻到一根据说要退还厂家的三星的USB数据线型号是三星SGHX628手机数据线,芯片是2303HX (在这里感谢恩山客服的指点^_^),
到手之后,百度一番,找不到此电路的原理图,又反想,是三星的手机数据线 ,那就查查Samsung SGH-X628接口的针脚定义吧,找了半天,只找到
此款型号的大范围的针脚定义
1,2 18,17 V_EXT_CHARGE charge input
3 16 AUX_SPK handsfree speaker out
4 15 TXD1 serial 2 out for debugging purposes
5 14 +Vbat accumulator out
6,8,11 8,11,13 GND
7 12 REC01 power on/off scheme input
9 10 RXD1 serial 2 in for debugging purposes
10 9 AUX_MIC handsfree mic in
12 7 CHARGER_OK power on/off and charging control
13 6 JIG_REC power on/off scheme control
14 5 CTS serial 1 CTS
15 4 RTS serial 1 RTS
16 3 RxD serial 1 in used for data/ flash cable (shorted by R=22k to pin 18 in cable)
17 2 TxD serial 1 out used for data/ flash cable (shorted by R=22k to pin 18 in cable)
18 1 +Vbat accumulator out
于是心急火燎的把接口正数一番后,就把第2、3、针脚给拆了,
按照WZERSG54 的TTL定义给2TxD3RxD接了 ,
打开超级终端又按照K版主的指示115200-8-无-2-无设置一番后,
通上电源后 ,屏幕依然未果 ,脑子一片空白。
愣过神后,又把2、3的对调一番仍是未果!
难道我有接错了!
光看电路板有谁能判断出来那个是RX/TX吗?
终于显示出来了 是那里出了问题呢
