Typedef Documentation

typedef enum led_state led_state

Led state.

States for the LEDs control.

Enumeration Type Documentation

Variable Documentation

UInt8 led_control

led_control has different uses for red and green LEDs.

Red LED use this to determine his next state and delay, while green use to count how many requests it have to be on. Green LED is off only if there is zero requests.

UInt16 led_redCfg

Configuration of the red LED.

Last 4 bits (less significant) are the number of times the LED will blink, remaining 12 bits (more significant) are the time (ms) that LED will be off before blink again.
