I need some guidance regarding the parsing and de-serialization of binary data received from a character device in Linux. I’m working on writing a program in rust that monitors keyboard input used for various functions on my device. From the research I’ve done, the data should be parsed out into an input_event struct.

struct input_event {
struct timeval time;
__u16 type;
__u16 code;
__s32 value;
};

The problem I’m currently facing is that this doesn’t describe the entire block of data I receive from the character device which looks like the following:

[C, F5, 8F, 66, 0, 0, 0, 0, 33, 1A, 1, 0, 0, 0, 0, 0, 1, 0, 1D, 0, 1, 0, 0, 0, C, F5, 8F, 66, 0, 0, 0, 0, 33, 1A, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]

I can easily assume that the last 64 bits make up type, code, and value, but I can’t seem to calculate the time stamp accurately.

Could someone lend me some guidance on how this data is parsed correctly?
