你好,
我尝试使用12位SAR ADC,并且我没有注意到系统是在3.3V模式,并且为了测试,我已经连接了5V到ADC的输入。一段时间后,我看到评估板的LeD4和LeD3开始发光,PSoC芯片变热了。我关掉了。之后,每当我试图连接电源时,LeD4和LeD3都发光,PSoC代码不启动。即使我也不能闪亮新代码。我也尝试使用MixPrim3,但没用。 请建议仍然可以固定或董事会不见了。当我正在连接时,我得到下面的屏幕(下面附上) 谢谢您。 当做, 扎法尔 PNG 106.5 K 以上来自于百度翻译 以下为原文 Hi, I was trying to use 12 bit SAR ADC, and I did not notice that the system was in 3.3v mode and for testing I have connected 5v to the input of ADC. After some time I saw the LED4 and LED3 of the evalaution board started glowing and the PSoC chip became hot. I switched off. After that everytime whenever I am trying to connect to power supply both of the LED4 and LED3 is glowing and PSoC code is not booting. Even I am not able to flash the new code. I tried using miniprog3 also but it did not help. Please suggest still this can be fixed or the board is gone. When I am connecting I am getting following screen (attached below) Thank you. Regards, Zafar

我认为电路板已经消失了,因为您可以在PoSo5LP数据表页的第67页(在下面的链接上看到),“GPIO上的DC输入电压”最大值是VDDIO+0.5V:

muuwfwr 发表于 2018-9-12 18:27 嗨,Anks, 谢谢你的回复。 那么如果我在评估板中替换IC(MCU)应该工作吗? 谢谢。 当做, 扎法尔 以上来自于百度翻译 以下为原文 Hi Anks, Thanks for your reply. So If I replace the IC( MCU ) in the evaluation board should it work? Thanks. regards, Zafar |

你好,
请检查PSOC 5LP的VCCD引脚。该电压是器件的输出电压。如果这个电压不显示为1.8V,你的设备可能已经损坏。 更换前,在取出P5LP后检查板的所有点的电压。如果电压良好,请继续更换。之后会奏效的。 当做 尼尚特 以上来自于百度翻译 以下为原文 Hi, Please check the VCCD pin of the PSoC 5LP. This voltage is the output voltage of the device. if this voltage doesnt show up to be 1.8V, you device may have been damaged. Before replacing, check the voltage at all points of the board after removing P5LP. If the voltages are fine go ahead and replace it. It will work after that. Regards Nishant |

60user124 发表于 2018-9-12 18:52 你好, 谢谢你的建议,我检查了VCCD引脚,可以看到它显示出1.72V。但是其他测试点(VDDA)在3.3V和5V模式下都显示出2.3V。因此,继续改变IC是很好的。 谢谢您。 当做, 扎法尔 以上来自于百度翻译 以下为原文 Hi, Thanks for your suggestion, I checked the VCCD pin and can see that it is showing up 1.72v. but the other test points (VDDA) is showing up 2.3v in both (3.3v and 5v ) mode. So is it fine to go ahead and change the IC. Thank you. regards, Zafar |

你好, 系统设置为5V,(跳线设置在5V) VDDD显示3.8伏。 VDDA显示2.3伏 VCCA显示1.8伏特 谢谢 当做, 扎法尔 以上来自于百度翻译 以下为原文 Hi, System is set to 5v,(jumper setting is in 5V) VDDD is showing 3.8 Volt. VDDA is showing 2.3 Volt VCCA is showing 1.8 Volt Thanks regards, Zafar |

嗨,Zafar,
谢谢你的数据。我们还应该检查调节器的输出。在添加跳线和添加VDD选择跳线之后,给我这个数据。这将使设备与调节器输出隔离。 请把附件中的红十字资料给我。 以上来自于百度翻译 以下为原文 Hi Zafar, Thanks for the data. We should also check the regulator output on board. Give me this data before adding the jumper and after adding the VDD selection jumper. This will isolate the device from the regulator output Please give me the data with red cross in the attached picture |

你好,
有什么更新吗?你改变了设备还是测量了我提到的电压? 当做 尼尚特 以上来自于百度翻译 以下为原文 Hi, Any updates? Did you change the device or measured the voltages I mentioned? Regards Nishant |

你好尼森 对不起,我在外面呆了几天,我们从主板上拆下了控制器,并订购了新的。今天我将检查电压水平并更新你。 谢谢您。 当做, 扎法尔 以上来自于百度翻译 以下为原文 Hi Nishant Sorry I was out for few days, here we have removed the controller from the main board and ordered the new one. Today I will check the voltage level and update you. Thank you. regards, Zafar |

你好,
当然。由于您移除了设备,如果所有电压都正常,它肯定是设备,否则它应该是一个调节器或它周围的电路。 当做 尼尚特 以上来自于百度翻译 以下为原文 Hi, Sure. Since you removed the device, if all voltages are OK, Its definitely the device, else it should be a regulator or the circuitry around it. Regards Nishant |
