推荐答案

要做的第一件事是确保已与摄像机建立通信.
假设您已经可以通过某种方式与之交谈，则该手册非常清楚您必须执行的操作.拍照:

向摄像机发送5个字节的序列:0x56 0x00 0x36 0x01 0x00
它将与您对话并返回5个字节:0x76 0x00 0x36 0x00 0x00

这大概意味着接受".

读取文件似乎也不太困难.
老实说，这本手册并不是我见过的最好的手册，但绝不是最糟糕的手册.

返回JPG文件要复杂一点，因为数据是按块发送的，但并不复杂.您要做的就是依次请求每个块-甚至还有流程图说明如何做！

The first thing to do is to make sure you have established communications with the camera.
Assuming you can talk to it in some way already, the manual is pretty clear about what you have to do. To take a picture:

Send the camera a sequence of 5 bytes: 0x56 0x00 0x36 0x01 0x00
It will talk back to you and return 5 bytes: 0x76 0x00 0x36 0x00 0x00

This presumably means "Taken ok".

To read the file doesn''t look too difficult either.
To be honest, the manual isn''t the best I''ve seen, but it by no means the worst.

It''s a little more complex to return a JPG file, because the data is sent in blocks, but it''s not complex. All you have to do is request each block in turn - there is even a flow chart explaining how to do it!
