如何在没有任何驱动程序的情况下从USB读取数据？ [英] How to read from USB without any driver?

问题描述

我们正在创建具有GPS接收器和PC的小型系统。我们想测试我的GPS接收器，我们不想第一次去找司机。首先，我想测试我的电路是否正常工作。 GPS IC已设置为输出NMEA语句。我们需要一个仅从USB端口读取数据并将其打印在屏幕上的程序。

We are creating small system which has GPS receiver and PC. We want to test my GPS receiver, We do not want to go for a driver on the first go. First I would like to test my circuit works or nor. GPS IC has been set to output NMEA sentence. We want a program which just reads data from USB port and print it on the screen.

我们可以轻松编写这样的东西吗？我们是否有任何开源工具可以实现此目的？

Can we write something like this easily ? Do we have any open source tool which will achieve this purpose ?

推荐答案

所有设备都需要一个驱动程序，因此我将解释为我如何仅使用操作系统提供的驱动程序从GPS读取NMEA数据，所以我不必写我的驱动程序。拥有吗？

All devices need a driver, so I'm going to interpret your question as "how can I read NMEA data from my GPS using only drivers provided by the OS, so I don't have to write my own?"

如果GPS芯片具有USB接口，那么您应该已经有了驱动程序。但是大多数GPS芯片都有一个UART接口，在您看来，它听起来像是连接到单独的USB-UART转换芯片上。该转换芯片很可能也附带了驱动程序，但是，如果没有，您可以跨接转换芯片的复位引脚，将其禁用，然后将TTL / RS-232电平转换器（现成的）连接到

If the GPS chip has a USB interface, then you should have gotten a driver with it. But most GPS chips have a UART interface which in your case sounds like it is connected to a separate USB-UART conversion chip. That conversion chip most likely came with a driver as well, but if not, you could jumper the reset pin of the converter chip, disabling it, and then attach a TTL/RS-232 level converter (available off-the-shelf) to the UART traces and then to your computer's serial port.

除非您怀疑USB-UART转换器的驱动程序会引起问题，否则我不会打扰。

Unless you suspect that the driver for the USB-UART converter is causing problems, I wouldn't bother.
