您好!
我已经用DC电源适配器为CY45 31工具箱供电,并且使用EZ-PD配置实用软件,我正在尝试建立源配置文件。当C型电源适配器连接时,我可以轻松地设置不同的接收器配置文件。不幸的是,无论源简介我设置的,当我在输入功率测量头(J12),我读到24V。我怎么设置的源文件,可以输出5V输入标题说的吗? 以上来自于百度翻译 以下为原文 Hi I have powered the CY4531 kit with the DC Power Adapter and using the EZ-PD Configuration Utility software, I am trying to set up the source profiles. I was easily able to set up the different sink profiles when the Type-C Power Adapter was connected. Unfortunately whatever source profile I set up, when I measure at the Input Power Headers (J12), I read 24V. How can I set up the source profile so that I can output say 5V at the input header? |

嗨,Bilalm,
J12直接与直流电源适配器的输入连接。所以,如果你使用直流电源适配器,电压总是24V。 如果你想读你的源配置文件,你会阅读UBSpPypWR。 谢谢。 以上来自于百度翻译 以下为原文 Hi Bilalm, The J12 is directly connected with input of DC Power adapter. So, the voltage always 24V if you are using DC power adapter. If you want to read your source profile, you will read the USB_P_PWR. Thanks. |

嗨,比拉尔, 您可以在靠近SSYUSB类型-B容器J2附近的测试点上读取“UBSpPypWR”。 槽电压可以阅读的u***_c_pwr试验点,旁边就是5-20v输出头J7。 参考指南:http://www.cypress.com/file/230181/download EVK 当做, 拉贾斯 以上来自于百度翻译 以下为原文 Hi Bilal, You can read 'USB_P_PWR' on a test point brought out near the SS_USB Type - B receptacle J2. The sink voltage can be read on 'USB_C_PWR' test point which is right beside the 5-20V output header J7. Refer the EVK guide: http://www.cypress.com/file/230181/download Regards, Rajath |

zhanan5193 发表于 2018-9-5 10:25 嗨,Rajath, 我现在读的u***_p_pwr通过测试点,但究竟源简介我通过配置实用软件,我只能读到5V的。请告诉我,我如何能读到不同的电压如15V。 当做, 比拉尔 以上来自于百度翻译 以下为原文 Hi Rajath, I am now reading 'USB_P_PWR' through the test point but what ever source profile I set through the configuration utility software, I can only read 5V. Please inform me on how I can read a different voltage such as 15V. Regards, Bilal |

ewtywtwy 发表于 2018-9-5 10:40 你好,比拉尔, 对于UBSpPypWR显示PDO电压,PDO应该在成功的PD合同之后被接收器接受,并且源应该开始提供该电压。通过使用协议分析器(CY4500 CC嗅探器),您需要检查是否已经与接收器建立了一个成功的PD合同。 当做, 拉贾斯 以上来自于百度翻译 以下为原文 Hello Bilal, For USB_P_PWR to show the PDO voltage, that PDO should have been accepted by the sink after a successful PD contract and source should start supplying that voltage. You need to check if a successful PD contract has been established with the sink, by using the protocol analyzer (CY4500 CC sniffer). Regards, Rajath |

zhanan5193 发表于 2018-9-5 10:57 嗨,Rajath, 谢谢,这很有道理。 它有一种方式,我可以确认源/汇'电流',而不必使用协议分析仪? 最好的问候, 比拉尔 以上来自于百度翻译 以下为原文 Hi Rajath, Thank you, that makes sense. It there a way that I can confirm the source/sink 'current' without having to use the protocol analyzer? Best Regards, Bilal |

嗨,比拉尔,
你用什么来吸收力量? 您可以使用预先配置的接收器(可能是另一个工作EVK或已知的工作设备)从电源中提取电源,然后测量电压/电流。这只会告诉你这个合同是否是成功的,什么样的电压来源于,但是它将不可能进一步调试没有阅读PD交通。 另一种方式是如果你可以连接一个外部控制器,它可以用来与PD控制器的交流和了解这。 当做, 拉贾斯 以上来自于百度翻译 以下为原文 Hi Bilal, What are you using to sink power? You can use a pre-configured sink (probably another working EVK or a known working device) to draw power from your source and then measure the voltage/current. This will only tell you whether the contract was successful and what voltage is being sourced, but it'll not be possible to debug further without reading the PD traffic. Another way is if you can interface an external controller, it can be used to communicate with the PD controller and get information about this. Regards, Rajath |

zhanan5193 发表于 2018-9-5 11:30 你好,拉贾什, 现在我用C型电源适配器作为电源,EVK作为电源接收器。所以基本上我想吸收电流,通过设置配置工具软件和观察测量精度不知何故。我没有进入协议分析仪,所以我想知道如果有另一种方式去做? 谢谢, 比拉尔 以上来自于百度翻译 以下为原文 Hello Rajash, Now I am using a Type-C power adapter as the power source and the EVK as the power sink. So basically I wanted to somehow measure the sink current that was set through the configuration utility software and observe the accuracy. I don't have access to a Protocol Analyzer so I was wondering if there is another way to do it? Thanks, Bilal |

ewtywtwy 发表于 2018-9-5 11:43 比拉尔 你可以连接适配器到您的EVK和测量电压的u***_c_pwr”协商的沉。 目前提到的水槽PDO将最大电流将绘制。任何更高的电流会触发OCP(过电流保护)。你有访问5-20v输出标题这一谈判的权力,J7。你可以连接在J7负载你的选择和验证电流与电流表。 请确保你有过电压、过电流保护功能的配置权力从J7在绘制时。 最好的问候, 拉贾斯 以上来自于百度翻译 以下为原文 Bilal, You can connect the adapter to your EVK and measure the negotiated sink voltage on 'USB_C_PWR'. The current mentioned in the sink PDO will be the maximum current that will be drawn. Any higher current drawn will trigger OCP (over current protection). You have access to this negotiated power on 5-20V output header, J7. You can connect a load of your choice on J7 and verify the current drawn with an ammeter. Please make sure you have over voltage and over current protection enabled during configuration when drawing power from J7. Best regards, Rajath |
