* Some comments on the structure of send_buffer, image_buffer,
|
|
* and receive_buffer:
|
|
*
|
|
* send_buffer: The first two bytes are low order and high
|
|
* byte of the command, followed by at least two
|
|
* more bytes. The number of sent bytes has to be
|
|
* even.
|
|
*
|
|
* image_buffer: This buffer will contain raw data like
|
|
* jpeg or exif data.
|
|
*
|
|
* receive_buffer: The first two bytes will be the same as
|
|
* in send_buffer. This will be checked
|
|
* here. Then will follow low and high
|
|
* order byte of the return status. After
|
|
* that, depending on command and return
|
|
* status, other bytes will follow.
