controller LCD display module is very simple. There are two Methods: Through P0 and P2 interfaces, direct access is called; other I/O Ports (such as P1, P3, or extended I/O Ports) are called indirect access methods.
The single-chip microcomputer uses the T6963C controller to access the Display memory,
It is usually divided into two steps:
① Send address pointer,
② Read/write display data (C/D = "0"), or ① send address pointer, ② send Operation Command (C/D = "1 ").

3. Multiplier program Design ideasFirst consider the input semaphore, there is a multiplier and the multiplier, there is a start instruction (start_sig), the equivalent of We enter the calculation formula in the calculator, and then press the next "= "number, get the final result. Then consider the
The classic 8 digital problem mainly uses the "ordered search algorithm" in artificial intelligence, which is also called a algorithm.

valid.First, we get the product of the first 17 bits and [(5*7) + (3*9) + (0*10) + (1*5) + (0*8) + (2*4) + (1*2) + (9*1) + (2*6) + (0*3) + (0*7) + (5x9) + (0x10) + (8x5) + (0x8) + (1x4) + (1x2)] is 189, then divide 189 by 11 and the result is 189/11 = 17----2, that is, the remaining number is 2. Finally, we can use the corresponding rules to know that the check code corresponding to remainder 2 is X. Therefore, it can be determined that this is a cor
parent function equation, the ②, the solution of the female function equation, the ③, the female function becomes the power series form.
So the generation function of the Fibonacci sequence is: G (x) =x+x2+2x3+3x4+5x5+8x6 ....
Both sides of the equation are *x: XG (x) =x2+x3+2x4+3x5+5x6+8x7+ ....
Add: G (x) +xg (x) =x+2x2+3x3+5x4+8x5+13x6+ ...
We compare g (x) to get: g (x) +xg (x) =g (x)/x-1; So we can get: g (x) =x/(1-X-X2).
Can make: 1-x-x2=0, get

Let's figure this out:
For example, each page plus 8, there are 5-6 navigation pages, 8x5=40 (a keyword). There are products, news classification, news articles, product map ... 10 pages, 8x10=80 (a keyword). And our G3 website is more than 10 pages, 8x20=160, 8x30=240 ...
According to the weight of the site page is different, we will keyword grading to add.
In general, we divide the keywords into five levels:
