嗨,各位,
我有一个无线遥控器,基本上我想把无线接收器的输出连接到我的PSOC1微控制器上的输入来控制一些外部设备。 不幸的是,无线接收器继电器的输出是12伏,输入是5V,我的问题是,我可以只使用一个5V调节器,如L7805,并添加电容器,以确保其稳定的电压,如在下面的图表? 谢谢 以上来自于百度翻译 以下为原文 Hi folks, Ive got my hands on a wireless remote control, Basically i want to connect the output from the wireless receiver to an input on my PSoC1 microcontroller to control some external devices. Unfortunately the output of the wireless receivers relay is 12volts and the inputs are 5v, my question is can i just use a 5v regulator such as the L7805 and add capacitors to make sure its a stable voltage such as in the diagram below? Thanks |

我知道Dana Knight和Bob Marlowe所说的关于使用简单的方法来实现代码是基于PSoC的初学者/新手的,但是天啊,我对你的代码感觉很好,而且会坚持下去,只是我在LoL上有点慢。
以上来自于百度翻译 以下为原文 I know what Dana Knight and Bob Marlowe were saying about using simpler methods of implemeting the code based on being a beginner/novice at PSoC but gosh darn ive a good feeling about your code and would stick with it, its just im a little slow at it lol |

如果你试图从12V电源PSoC
1)线性调节器通常不太吵,所以如果你正在做精密模拟。 考虑一下这个。 2)切换器可以有更宽的输入范围,事实上有部分将被降压或升压。 在输入电源上,像一个高启动的电池组(降压模式下的稳压器),然后下降。 低于期望的Vdd(SWITESS超过升压模式)。 3)TI,国家,Micrel,LT,菲利普斯是供应商的一部分。NSC/TI有在线设计 选择和设计和评估设计性能的工具。抨击轰炸。 问候,Dana。 以上来自于百度翻译 以下为原文 If you are trying to power PSOC from 12V - 1) Linear regulator typically a lot less noisy, so if you are doing precision analog consider this. 2) Switcher can have wider input range, in fact there are parts that will buck or boost depending on input supply, like a battery pack that starts out high (regulator in buck mode) and then drops below desired Vdd (swicthes over to boost mode). 3) TI, National, Micrel, LT, Phillips are just some of the providers. NSC/TI have an online design tool to pick and design and evaluate a designs perfromance. Inclduing BOM generation. Regards, Dana. |

嗨,伙计们,
谢谢你的回复, 基本上,我想接口这些:HTTP://www. EBay.CO.UK/ITM/RF-无线-电气GARGA-GATE门遥控器/310412645 844?Pt=UKSGoDigs&Hash=ITEM48 460915F2 随着PSOC 1上的输入,接收器继电器的输出对于PSoC上的输入来说太多了。我想把12V信号降到5V,然后用5V作为逻辑高电平。 以上来自于百度翻译 以下为原文 hi guys, thanks for the replies, Basically I want to interface one of these: http://www.ebay.co.uk/itm/RF-Wireless-Electric-Garage-Gate-Door-Remote-Control-/310412645874?pt=UK_Gadgets&hash=item48460915f2 with an input on my PSoC 1, the output from the receivers relay is 12vdc far too much for an input on the psoc. i was thinking of bringing the 12v signal down to 5v and then using the 5volt as a logic high. |

因此,具有两个“R”的分压器解决方案是最简单的。

然后一个简单的R除法器应该工作。你必须关心
随着电源排序,例如PSOC先启动,然后GD开机。 如果R分频器限制总电流到pSoC引脚注入电流规格 也许能同时把两个设备供电。 问候,Dana。 以上来自于百度翻译 以下为原文 Then a simple R divider should work. You do have to be concerned with power sequencing, eg. get PSOC started up first, then GD opener. If R divider limits total current to < PSOC pin injection current spec you might be able to get away with powering up both devices at once. Regards, Dana. |

嗨,家伙,我不知道如果我的继电器有他微控制器的输出,我还在等待它到达,但是我实际上有一些这些5V稳压器现在在这里和一些电容器,这将花费我任何东西组成一个小电路使用我建议的组件,我缺乏电阻thoug在说我可以使用我建议的设置。我也在考虑使用100UF和10UF电容器代替图中列出的电容器。说到这一点,在PSOC1设备上连接到接地的5VDC电源上安装滤波/平滑电容器是一个好主意,当我最终决定在PCB上运行它时,我自己来做。我想把一个0.01uF电容器穿过电源引脚并连接到接地上。任何想法,谢谢大家
以上来自于百度翻译 以下为原文 Hi guys, im not sure if my relay has he microcontroller output, I am still waiting for it to arrive, However I actually have a few of these 5v regulators here now and some capacitors, it would cost me anything to make up a little circuit using the components i suggested, Im short on resistors though. In saying that could I use the setup i suggested. I was also thinking of using a 100uF and a 10uF capacitor instead of the ones listed on the diagram. Speaking of which, is it a good idead to put a filtering/smoothing capacitor across the 5vdc supply connected to ground on the PSoC1 device when i eventually decide to run it on a pcb i make up myself. I was thinking of putting a 0.01uF capacitor across the supply pin and connect it to ground? any ideas, thanks guys |

在调节器输出时,你应该有一个体积和01或1陶瓷。散装大把手
电流开关瞬态,如驱动LED或大C负载,陶瓷照顾 高ESR批量帽不能产生更高的FRQ噪声。阅读你的调节器规范,确保 没有最低ESR帽规格的输出,有助于稳定管理。 问候,Dana。 以上来自于百度翻译 以下为原文 On regulator output you should have both a bulk and a .01 or .1 Ceramic. Bulk handles large current switching transients, like driving LEDs or large C loads, and the ceramic takes care of higher freq noise that the high ESR bulk caps cannot. Read your regulator specs, make sure there is no minimum ESR cap specs on the output that aid in stability management. Regards, Dana. |

不管你使用什么,只要记住限制输入引脚的电压低于VCC(VDD)。
我不会使用一个5V7齐纳钳位输入作为输入应小于5V。 我也会先测量你的ReaGuor的输出,它应该总是低于你的PSoC的VCC。 以上来自于百度翻译 以下为原文 No matter what you use, just remember to limit the voltage at the input pin lower then the VCC(VDD). I would not use a 5V7 zener to clamp the input as the input should less then 5V. I woudl also measure the output of your reguatlor first and it should always be lower then the VCC of your PSOC |

在5V7 i没有使用该电路的情况下,IVE使用4V7和100K电阻器来对PSoC的输入和输出提供一些保护,但是关于它,我打算回答之前关于编程的其他查询,我有点喜欢您所描述的方法,但IM有点CONF。关于它,我可能会很快重访,只是我很忙,也谢谢你的回复非常有用。
以上来自于百度翻译 以下为原文 with the 5v7 i wasnt using the said circuit, ive used 4v7's and 100k resistor to provides some protection to inputs and outputs on the psoc but thats about it, I meant to reply to the other query i had before about the programming, i kind of liked the method you were describing but im a little confused about it, i may revisit it soon, just that ive ben busy, also thanks for your replies very helpful |
