hi2c2 in an external .c

[MSole.1]

Hello to all.

I'm coding an I2C comunication and the IDE (1.4.0) create the Private variable I2C_HandleTypeDef hi2c2; and then the function MX_I2C2_Init. Everithing ok.

I'm using an external .c file to handle the I2C communication and how can I access to the hi2c2 from my read/write functions in my .c module?

Thanks in advance, Manu.

Add "extern I2C_HandleTypeDef hi2c2;" either in your .c file, or in an included header.
