Send custom structure over i2c

[rudasi]

I am trying to send a custom structure over i2c to a kinetis board which is acting as a slave with an interrupt triggering a callback in this scenario. I am able to run the example code which has a uint8_t buffer but I am not sure how to send a custom structure with different data types over. 

Any example code out there?

Hi, Rahul,

If you need complicated structure, I think you can use sprintf() function to output all variable to a buffer with char type, it is okay. If you want to output a structure, I think you can use union type structure.

typedef struct str_union

{

char array[];

union

{

}

}

Hope it can help you

Figured it out by just type casting the data to my structure.
