#define DRIVER_COUNT 2

#define RGB_MATRIX_LED_COUNT (DRIVER_1_LED_TOTAL + DRIVER_2_LED_TOTAL)
```
!> Note the parentheses, this is so when `RGB_MATRIX_LED_COUNT` is used in code and expanded, the values are added together before any additional math is applied to them. As an example, `rand() % (DRIVER_1_LED_TOTAL + DRIVER_2_LED_TOTAL)` will give very different results than `rand() % DRIVER_1_LED_TOTAL + DRIVER_2_LED_TOTAL`.
