### LED Blinking Defaults and Updated Values
The default LED blinking values defined in the SDK
(see the original lines here: [pico-keys-sdk `led.h` L53–L62](https://github.com/polhenarejos/pico-keys-sdk/blob/main/src/led/led.h#L53-L62))
were not always useful or easily distinguishable in practice.
To improve clarity, we updated the LED patterns as follows:
```c
enum {
MODE_NOT_MOUNTED = (MAX_BTNESS << LED_BTNESS_SHIFT) | (LED_COLOR_RED << LED_COLOR_SHIFT) | (1500 << LED_ON_SHIFT) | (1500 << LED_OFF_SHIFT),
MODE_MOUNTED = (MAX_BTNESS << LED_BTNESS_SHIFT) | (LED_COLOR_GREEN << LED_COLOR_SHIFT) | (3000 << LED_ON_SHIFT) | (3000 << LED_OFF_SHIFT),
MODE_SUSPENDED = (MAX_BTNESS << LED_BTNESS_SHIFT) | (LED_COLOR_BLUE << LED_COLOR_SHIFT) | (1000 << LED_ON_SHIFT) | (2000 << LED_OFF_SHIFT),
MODE_PROCESSING = (MAX_BTNESS << LED_BTNESS_SHIFT) | (LED_COLOR_GREEN << LED_COLOR_SHIFT) | (50 << LED_ON_SHIFT) | (50 << LED_OFF_SHIFT),
MODE_BUTTON = (MAX_BTNESS << LED_BTNESS_SHIFT) | (LED_COLOR_YELLOW << LED_COLOR_SHIFT) | (100 << LED_ON_SHIFT) | (100 << LED_OFF_SHIFT),
MODE_ALWAYS_ON = UINT32_MAX,
MODE_ALWAYS_OFF = 0
};
