我已经开始在启动工具包上与PSoC5建立一个UCB通信。一些背景,我已经:
下载CyPress套件USB 3.4.6读取HTTP://wwwyCysP.COM/?APP =论坛和ID;ID=2233和;RID=45.3,并连接到R22/R23作为指示(并由此取消了我的担保;^)在USB套件中构建USB固件(UBFSFSBLKKYWRAPAON-000)用于PSoC5,并编程了第一触摸硬件。当我把我的杰瑞挂载的USB设备插入我的电脑时,Windows通知“连接到这台计算机的USB错误之一已经发生故障。”我希望有一个简单的“不被认可”,但却有“故障”(!). 该死的鱼雷全速前进,我在许多不同的地方修改了CysBiNF多种不同的方法。因为我在Wi7上,所以我把它放在了……/Buff/BI/WXP/X86和/X64中。司机拒绝载重。 查看设备管理器,我发现一个未知的USB设备与匹配设备类GUID,但没有VID/PID时,我正在期待0x04B4/0x8051。我认为枚举过程失败得很严重。我不怪司机不上车。 我给D+/D附加了一个范围,并且发现了非常合理的外观行为。D+被拉高,D被拉低(我相信,把它识别为UB-FS)。我在范围内看到了大量的事务处理。信号在不同电压水平(0V/3.3V)出现不同。事务中的脉冲宽度与12MHz操作(整数83NSEC)一致。 我无法识别硬件或固件中的错误,但不能连接USB设备…帮助? 票据 P.S.谁认为最好的(也是唯一的)显示来自FirstTouch Kit的信息是“浪潮”?我的胳膊累了,该死的。 以上来自于百度翻译 以下为原文 I'm having touble establishing a UCB communication with the PSoC5 on the starter kit. Some background, I have already:
Damn the torpedoes full steam ahead, I have modified CYUSB.inf multitple different ways in multiple different places. I've placed it in .../Driver/bin/wxp/x86 and /x64 since I am on Win7. The driver declines to load. Looking thru device manager, I find an unknown USB device with a matching Device Class GUID but no VID/PID when I was expecting 0x04B4/0x8051. I think the enumeration process failed pretty badly. I don't blame the driver for not loading. I attached a scope to D+/D- and found pretty reasonable look behavior. D+ is pulled high and D- is pulled low (I believe, identifying it as USB-FS). I see a number of transaction flit by on the scope. The signals appear differntial and at rational voltage levels (0V/3.3V). The pulse widths in the transactions are consistent with 12MHz operation (integer mulitples of 83nsec). I cannot identify a fault in the hardware or firmware and yet can't attach the USB device....help? -bill P.S. Who thought the best (and only) way to display information from the First Touch Kit was "the wave"? My ARM is tired damn it. |

比尔,你是说你侵入FTK使用USB功能?你在PSOC5设备中烧的固件是什么?
以上来自于百度翻译 以下为原文 Bill, are you saying that you hacked in to the FTK to use the USB functionality. What was the firmware that you burnt in to PSoC5 device? |

我砍黑板,把PSOC5的USB插针带到上面的一个单独的连接器。更小的微(FTK?)用于管理程序接口未被触摸。我编程的PSoC与最简程序在USB套件中找到:除了从PSoC3到PSoC5的代码重定向,我没有改变任何东西。
以上来自于百度翻译 以下为原文 I hacked the board to bring out the USB pins for the PSoC5 to a seperate connector per the above forum entry. The smaller micro (FTK?) used to manage the program interface is left untouched. I programmed the PSoC with the minimalist program found in the USB suite: USB_Bulk_Wraparound. Except for retargeting that code from PSoC3 to PSoC5, I have not changed anything. |

这可能是由于电路板的电压配置。在您的代码中,您可能已经初始化PSoC操作在5V,并且该板可能在3.3V操作,反之亦然。对于电压选择,我想在第一个触摸套件上有一个跳线。你能翻动这个跳线并给它一个镜头(或者你可以翻转代码中的设置)。
如果你有CY8CITK-01或030或050,你可以尝试代码来确保代码工作正常。顺便问一下,你确信SUITEUSB能为PSoC3提供代码吗? 以上来自于百度翻译 以下为原文 This could possibly be due to the voltage configuration of the board. In your code you might have initialised PSoC to operate at 5V and the board might be operating at 3.3V or vice-versa. For voltage selection there is a jumper on the First Touch Kit i guess. Can you flip this jumper and give it a shot(or you can flip the settings in the code). If you have a CY8CKIT-001 or 030 or 050 you could try the code to make sure that code works fine. And by the way, are you sure SuiteUSB provides code for PSoC3 ? |
