UCHAR G_LN; //Green list number
UCHAR B_LN; //Blue list number
} LED_INFO, *PLED_INFO;
Remarks: The structure includes essential information to set LED IC.
D.6.2 _LED_BLNK_SET
Syntax: typedef struct _LED_BLNK_SET{
UCHAR Main_Addr; //Main address
BYTE BLNK_DutCyc; //Duty Cycle
BYTE BLNK_Freq; //Blinking Frequency
}LED_BLNK_SET, *PLED_BLNK_SET;
Parameters: Main_Addr [UCHAR] – IC address on I2C bus.
BLNK_DutCyc [BYTE] – Duty cycle of LED blinking. Duty cycle = (0 ~ 255)/256
= x%
BLNK_Freq [BYTE] – Frequency of LED blinking. 0x00 = (41ms, frequency
24Hz), 0xFF = (10.73s), Frequency = [(0~255) + 1]/24= x(second), Ex：300ms =
(7 + 1) / 24 ≒ 0.333s
Remarks: This structure is used to store the blinking duty cycle and frequency of LED IC.
Please note that one LED IC only has one duty cycle and frequency to be group
used. It means all LED has the same blink mode on a LED IC.
D.6.3 _LED_BLNK_TYPE
Syntax: typedef struct _LED_BLNK_TYPE{
UCHAR Main_Addr; //Main address
int BLNK_TYPE;
}LED_BLNK_TYPE, *PLED_BLNK_TYPE;
Parameters: Main_Addr [UCHAR] – IC address on I2C bus.
BLNK_Type [int] - Turn on/off blinking circuit on the LED IC. Defined by:
#define LED_BLNK_ON 0
#define LED_BLNK_OFF 1
Remarks: This structure is used to turn on/off blinking circuit on the LED IC.
