Led Blinking 功能驱动设计

Led blinking 

The LEDR, LEDG, LEDB, controlled by the 8806, can be programed to blinking by set the 8806 internal regs. Such as 0x0c,0x0d,0x0e,0x0f.

the difference between the 2 circuit is the resister value ,1 use 1k,and 2 use 0.

now I can only debug out the first blinking . maybe the second circuit has problems .

static int enable_led()
+{
+ char val = 0,count;
