Harbin University of Science and Technology software engineering 08-7 Li Wanpeng original works, the reprint please indicate the source of this is a schematic diagram, the rightmost one exclusion, is also here the eight resistor package together,UGG Boots Clearance, this exclusion is characterized by a eight resistor having a common terminal, and a power supply VCC by jumper and exclusion connected to.
Reach the diode current flows from positive to negative,Cheap Oakley sunglasses Shop, such as fruit diode anode is low,UGG Outlet Store, then the current flow through the diode, light emitting diode lights up.The negative electrode is connected with the SCM P2 port.
It is said that the P2 pin low level which can drive the light emitting diode.Drive all lights flashing method is to shift left,Moncler Shop, use the function _ crol _.# include < reg52.h> include < #; intrins.
h> unsigned int a; void delay () {int i,Five Fingers Shoes, J; for (I = 0; I < 0xff; I + +) for (J = 0; J < 0xff; j + +);} void Liushui () {int I, DD; DD = 0xFE; / / DD = 11111110 then L9 light for (I = 0; I 8;
