+##### yu-capteurs branch in function "oximeter2_read_data" optimisation
+
 **Context:**
 The library "oximeter2.h" on branch yu-capteurs is essentially the same thing as the [example code](https://github.com/MikroElektronika/mikrosdk_click_v2/blob/master/clicks/oximeter2/example/main.c) from the official github repo of MikroElektronika except a few modifications.
