Send custom structure over i2c

rudasi — Fri, 03 Feb 2017 18:34:15 GMT

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?

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

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
