怎么让linux主机通过USBUART与PSoC 5LP 050开发套件进行通信

欢迎来到PSOCS的迷人世界！
UBUART没有CTS和RTS信号。相反，它需要一个（标准）的驱动程序，模拟一个串行接口使用的数据来自USB。该驱动程序是用Windows和Linux，只是给谷歌一个机会为你找到它。

  Welcome in the fascinating world of PSoCs!
    USBUART does not have got CTS and RTS - signals. Instead it needs a (standard) driver which emulates a serial interface using the data coming from the USB. This driver is availlable for windows and for linux, just give google a chance to find it for you.

嗨，鲍伯，
谢谢你的回复。
事实上，我知道司机和我可以得到它的工作板下的设备名为TTYACM0或TTYACM1。董事会如果控制线路状态RTS关闭接收数据。如果RTS，董事会不能从主机接收数据。我猜当主机发送一个RTS的板，它等待一个CTS从板才开始发送数据。我看看线控制的变化发生在为（；；）在main() viau***uart_islinechanged()环
到目前为止，我所能做的是在主机上的电源，我需要拔掉USB电缆和插头的时候BIOS初始化后（或在OS加载。）在这种情况下，RTS是关闭的，董事会可以从主机接收数据。如果我如果USB线插上电时，RTS永远是对的。我不知道BIOS做的USB接口，但这可能是另一个问题。
最好的问候，托尼

  Hi Bob,
    Thanks for your reply.
    Actually, I know the driver and I can get it works with the board under the device names as ttyACM0 or ttyACM1. The board can receive data if the control line state RTS is off. If the RTS is on, the board cannot receive any data from the host. I guess when the host sends an RTS to the board, it waits for a CTS from the board before beginning to send data. I can check if line control changes happen in the for (;;) loop in main() via USBUART_IsLineChanged()
    Up to now, what I can do is before powering on the host, I need to unplug the USB cable and plug it back on after the BIOS initialization (or during the OS is being loaded.) In this case, the RTS is off and the board can receive data from the host. If I if the USB cable plugged when powering on, the RTS is always on. I don't know what the BIOS do to the USB interface, but this might be another issue.
    Best Regards,
Tony
 

RTS仅用于半双工。你能确保你的主机被定义为全双工吗？

  RTS is used for half duplex only. Can you make sure that your host is defined for full duplex?

对不起，迟到了。
主机支持全双工和半双工模式。它看起来像主机尝试失败后就切换到半双工全双工。
我的研究使我的地方，让我觉得RTS不应该是一个问题。这个问题可以依靠USB总线初始化BIOS，因为如果我将USB电缆插在OS加载它会好的。但是，我有其他的设备进行通信，以及与主机连USB电缆插在主机上电。我仍然不知道什么是错与PSoC板或如果我做错了什么。

   Sorry for late response.
    The host supports both full-duplex and half-duplex modes. It looks like the host tries to switch to half-duplex after it failed with full-duplex.
    My investigation leads me to somewhere that makes me think that RTS should not be an issue. The issue could rely on USB bus initialized by BIOS because if I plug the USB cable during the OS loading it would be fine. However, I have other devices that communicate well with the host even the USB cable is plugged before the host is powered on. I still don't know what wrong with the PSoC board or what if I did anything wrong.
