If you copy the i2c_manager files to your own component instead of
|
||
|
|
depending on i2c_manager, you MUST uncomment the define below
|
||
|
|
and put in some short string that identifies your component (such
|
||
|
|
as 'xyz'). This will cause i2c_manager to create functions named
|
||
|
|
xyz_i2c_* instead of i2c_manager_*. See README.md for details.
