使用C#程序为Cannon EOS Rebel XS创建USB时间间隔 [英] Creating a usb time lapse for Cannon EOS Rebel XS using a c# program
问题描述
我想知道这是否有可能.我想制作自己的软件来通过远程快门释放来控制快门释放.从图中可以看到，它具有3.3v(空载)和1.8v的阈值电压.我想知道如果我理解正确，是否可以使用限制5.25v左右的usb电缆电压.这是否有可能，还是我需要寻找新的方向.我希望用我相当有信心的c#编写软件.
预先感谢您的帮助:)
I am wondering if this is even possible. I want to make my own software to control the release of the shutter via the remote shutter release. From the diagrams I have seen it has a 3.3 v (no load) and a threshold voltage of 1.8v. I am wondering if I can use limit a usb cables voltage which is around 5.25v, if I am understanding correctly. Is this even possible, or do I need to look in a new direction. I am hoping to write the software in c# which I am fairly confident in.
Thank you in advance for your help :)
推荐答案
我在索尼Alpha和DSLR的佳能产品线中都使用了这类快门遥控器.对于加农炮，通常是2.5毫米立体声插头.它具有3个触点:接地，聚焦和快门.短路它们中的每一个，您将在相机中触发该功能.
I've played a lot with these type of shutter remotes, for both the sony alpha and for the canon line of dslr's. For the cannon, it is usually a 2.5mm stereo plug. It has 3 contacts: ground, focus and shutter. Shorting each one of them and you will trigger that function in the camera.

几年前，我设计了自己的电路，该电路将接收来自主机(在我的情况下为HP Pocket PC)的串行命令，并使用微控制器的GPIO端口将其中一根线驱动下来.
A few years ago, I designed my own circuitry that would take serial commands from the host (in my case an HP Pocket PC) and drive one of the lines down using a microcontroller GPIO port.
如今，类似设备的连接和控制选项更加简便.而且，如果您想走DIY之路，可以使用arduinos这样的非常不错的选择，或者如果您是c#上瘾者，则可以使用netduinos.
Nowadays there are similar devices with much easier connection and control options. And if you'd like to take the DIY road, there are very nice options such as the arduinos or if you're a c# addict, there are the netduinos.
