你好,
当我直接连接逻辑低“0”到数字输出引脚,似乎输出引脚应始终是Low,但它总是高电压时,我检查了数字万用表输出引脚。 为什么它的产量总是很高? 最好的问候, … 添加我的项目。如果你有什么问题,请告诉我。 SigWr.I.CyWrk.CaseV01.Zip 416.2 K 以上来自于百度翻译 以下为原文 Hello, When I directly connect Logic Low '0' to Digital Output Pin, it seems that the output pin should be always Low but it is always high voltage when I checked the output pin with Digital Multimeter. Why is its output always high? Best regards, ... Add my project. if you find any problem, please let me know anything.

我假设钳工优化了未使用的(总是零)引脚。由于没有时钟可以切换输入,所以它将在初始化期间保持不变。
出路:删除HADWORD连接,并将初始驱动模式设置为“强”和“低”。 鲍勃 以上来自于百度翻译 以下为原文 I assume that the fitter optimizes-out the unused (always zero) pin. Since no clock can toggle the input it will stay as during initialization. Way out: Remove the hadware connection and set the initial drive mode to "strong" and "low". Bob |

你好,
是的,如果你把一个逻辑“0”连接到一个被配置为“硬件连接”的输出引脚,应该给出一个逻辑电平“0”。 请检查您的PIN配置如下: 参考附上的项目。 -吉安 设计02.CyPRJ.CaseV01.Zip 443.8 K 以上来自于百度翻译 以下为原文 Hello, Yes , if you have connected a Logic '0' to an output pin configured as 'Hardware Connection' should give a logic Level '0'. Please check your pin configuration as below - Refer the attached project. -Gyan

你能再仔细检查一下针上是否有外部拉力? 你用哪一个PIN /芯片/板来测试这个案例? 我尝试了KIT-042,使用了P0Y0。 使用逻辑“0”来连接引脚内部。数字万用表的结果为0V。 使用逻辑“1”来连接引脚内部。数字万用表的测试结果为5V。 谢谢, 赖安 以上来自于百度翻译 以下为原文 Okegawa-san, Could you double-check if there is any external pull-ups on the pin? Which pin in which kit/chip/board were you using to test the case? I tried with KIT-042, used P0_0. Used logic '0' to connect the pin internally. The result of digital multimeter is 0V. Used logic '1' to connect the pin internally. The result of digital multimeter is 5V. Thanks, Ryan |

针是油炸的。将初创状态设置为0。如果编程后显示+5V,引脚的高端FET是油炸的。
ODISSEY1 以上来自于百度翻译 以下为原文 It is possible that pin is fried. Set the initial state on startups to 0. If after programming it shows +5V, the pin's high-side FET is fried. /odissey1 |

你好,Gyan san, 我检查了我的项目,PIN配置与项目完全一样,除了PIN位置。我使用的是CY8C4045 AZI S413的P0O0。 我还检查了CY8CIT-145-40XX,PSOC4000原型。 谢谢和问候, 以上来自于百度翻译 以下为原文 Hello Gyan-san, I checked my project and the pin configuration is perfectly same as your project except Pin position. I use P0_0 of CY8C4045AZI-S413. Also I checked this on CY8CIT-145-40XX, PSoC4000S Prototyping it. Thanks and regards, |

你好瑞安, 我再次检查了原理图,但没有上拉寄存器。该引脚通过820欧姆电阻连接到LED。我使用CY8CIT-145-40XX,虽然我划分了子面板,包括滑块触摸传感器和检查P0O0引脚电压,P0E0总是高的,大约4.74V。 谢谢和问候, 以上来自于百度翻译 以下为原文 Hello Ryan-san, I checked schematic again but there is no pull-up register. That pin is connected to LED through 820 ohm resister. I use CY8CIT-145-40XX and although I divided the sub board including slider touch sensor and checked P0_0 pin voltage, the P0_0 is always high, about 4.74v. Thanks and regards, |

zhan81411 发表于 2018-9-13 15:33 在这个设备中没有宏单元允许这个硬件连接。造物主不应该允许。当我连接逻辑1时,它会引发错误。创建者可以在调用main函数之前通过编写初始化代码来优化它。函数CyFiTeLyCFG~()中的PIN初始化代码似乎是在PIN定制器窗口中出现的,而不是基于它连接到的逻辑级别。我已经要求软件小组去研究一下。 谢谢你通知我们。作为一种解决方案,请检查PIN定制器窗口中的硬件连接,并控制固件中的PIN逻辑电平。 -拉吉夫 以上来自于百度翻译 以下为原文 There are no macro cells in this device to allow this hardware connection. Creator should not have allowed. It throws error when I connect Logic 1. Creator can possibly optimize it by writing initialization code before calling main function. Initialization code for the pin in the function cyfitter_cfg() seems to be taking what is appearing in the pin customizer window and not based on what logic level, it is connected to. I have asked the software team to have a look into it. Thanks for bringing it to our notice. As a workaround, please uncheck hardware connection in the pin customizer window and control the pin logic level in firmware. -Rajiv |
