管它会溢出的情况了。 （6）如果是中断的方式就开启中断设置中断标志位，编写中断服务函数等 7）然后读取CxH,CxL中的数据（如 data=(C1H)<<4+C1L

超声波主要用于泊车测距、辅助刹车等，量程较短等，然而在倒车辅助过程中，超声波传感器通常需同控制器和显示器结合使用，从而以声音或者更为直观的显示告知驾驶员周围障碍物的情况，解除驾驶员泊车、倒车和起动车辆时前后左右探视所引起的困扰，并帮助驾驶员扫除视野死角和视线模糊的缺陷，提高驾驶安全性。

我曾经使用签证和binblockread从pna 5247A用matlab获取数据。但是，我们现在没有PC环境，只能使用苹果笔记本电脑，我们只能在操作系统中使用tcpip和fread。代码如下：VNA = tcpip（''*。*。*。*'，5025）; set（VNA，'InputBufferSize'，30000）; set（VNA，'Timeout'，150）; fopen（VNA）fprintf（VNA，'CALC：PAR：SEL“CH1_S11_1”'）; fprintf（VNA，'FORM：BORD SWAP'）; ％将数据类型设置为实数32位二进制块fprintf（VNA，'FORM REAL，32'）; fprintf（VNA，'CALC：DATA：S2P 2'）; ％data1 = scanstr（VNA）; ％fwrite（VNA，'OUTPDATA'）; ％从binblock读出#A temp = fread（VNA，2，'char'）％读出块大小temp = fread（VNA，1，'uint16'）％读出跟踪数据data1 = fread（VNA，temp / 4） ，'float32'）; 'fread'可以读回#A和blocak的大小，有时虽然需要很长时间。但是，它无法读回跟踪数据。我应该用哪个命令快速恢复数据。编辑：lzuxz于2013年2月7日上午7:41 以上来自于谷歌翻译 以下为原文I used to get data with matlab from pna 5247A by using visa and binblockread. However, we now have no pc environment, and only a apple laptop could be used，we could only use the tcpip and fread in OS. The code is following: VNA=tcpip(''*.*.*.*',5025); set(VNA, 'InputBufferSize', 30000);set(VNA, 'Timeout', 150); fopen(VNA) fprintf(VNA, 'CALC:PAR:SEL "CH1_S11_1"'); fprintf(VNA, 'FORM:BORD SWAP'); % Set data type to real 32 bit binary block fprintf(VNA, 'FORM REAL,32'); fprintf(VNA, 'CALC:DATA:S2P2'); % data1=scanstr(VNA); % fwrite(VNA, 'OUTPDATA'); %Read out #A from binblock temp=fread(VNA, 2, 'char') %Read out block size temp=fread(VNA, 1, 'uint16') %Read out trace data data1=fread(VNA, temp/4, 'float32'); 'fread' could read back the #A and the blocak size, sometimes, although it need a very long time. However,It could not read back the trace data. Which command should I use to get the data back quickly.Edited by: lzuxz on Feb 7, 2013 7:41 AM

Do I need to change the bit rate or do I need to change the Config for Full speed and High Speed as well as Superspeed?I increased the"payload" in glProbeCtrl in 48KB (0xC000) is there anywhere eleseI need to change that? Maybe in uvc.h?
