我覺得很好用喔

PROGRAM_3

這支程式和PROGRAM_1一樣,但它在TIMER_2的地方不一樣,這樣的結果,在實際執行上會造成

什麼樣的結果呢?

"程式其他部分一樣,省略參照PROGRAM_1

void Timer_Interrupt_2() interrupt 5

{
T2CON = T2CON & 0X7F; //CLEAR TIMER2 INT_FLAG

// BIBI = !BIBI ;

if (scan_cnt>3) {scan_cnt=0x00;}
// 注意基本上以下4個IF會依順序 ,往下執行且每次都是如此

// 但程式本意是希望進入timer2後,馬上去執行,要顯示的位數就馬上離開

// 所以多了每次依順序比較scan_cnt等於多執行了些指令

if (scan_cnt==0)

{ P0=0XFF;

_ONE=0x00;

_TWO=0x01;

_THREE=0X01;

_FOUR=0X01;

disp = time_cnt % 10 ;

P0= _7_seg[disp] ;

scan_cnt ++ ;
}

if (scan_cnt==1)

{ P0=0XFF;

_ONE=0x01;

_TWO=0x00;

_THREE=0X01;

_FOUR=0X01;

disp = (time_cnt/10)%10 ;

P0= _7_seg[disp] ;

scan_cnt ++ ;
}

if (scan_cnt==2)

{ P0=0XFF;

_ONE=0x01;

_TWO=0x01;

_THREE=0X00;

_FOUR=0X01;

disp = (time_cnt%1000)/100 ;

P0= _7_seg[disp] ;

scan_cnt ++ ;
}

if (scan_cnt==3)

{ P0=0XFF;

_ONE=0x01;

_TWO=0x01;

_THREE=0X01;

_FOUR=0X00;

disp = time_cnt / 1000 ;

P0= _7_seg[disp] ;

scan_cnt ++ ;
}

看出來了嗎 ? 可看下圖 PROGRAM_3執行結果會變成這樣
但PROGRAM_1沒有這問題,而PROGRAM_2才是決解之道

再來 PROGRAM_2可以把TIMER_2裡的以下幾行移到MAIN內,這樣才不會浪費MCU執行效能

disp = time_cnt % 10 ;

disp = (time_cnt/10)%10 ;

disp = (time_cnt%1000)/100 ;

disp = time_cnt / 1000 ;

移到main中並且改為如下,

disp_0 = time_cnt % 10 ;

disp_1 = (time_cnt/10)%10 ;

disp_2 = (time_cnt%1000)/100 ;

disp_3 = time_cnt / 1000 ;

timer_2中的P0= _7_seg[disp] 也要跟著改,還有要宣告disp_0,disp_1,disp_2,disp_3喔

2008人工智慧單晶片電腦鼠暨機器人比賽在南台科大

10月5日剛好是星期天,所以專程帶Makoto及Masa去台南看電腦鼠比賽,到了台南竟然,進了台南科技大學,在其校園內晃了一圈,覺得有異為什麼沒有任何的海報呢?於是問了一下路過的同學,原來我這個外地人搞錯了,這裡不是南台科大 ,是台南科大,哈哈校名如此相近且位置也相差不遠,於是費了一番工夫終於到了南台科大,到的時後已接進比賽開始時間不遠,沒有太多時間拍照,在禮堂裡真是擠的滿滿的,這也是我第一次參觀這種展覽,哈只是看熱鬧的說,會場裡有比電腦鼠和lego nxt

NXP LPC2103

一直以來,布魯克都只用8051係列,制作上級交待的東西,當然也只有用組合語言而已,但最近很想改用C語言來設計東西,所以找了NXP 的LPC2103來試試,為什麼會選這個MCU呢?

因為我覺得用這顆MCU,它和51的腳數較接近,再者我目前用的51是笙泉的82G516,外型及腳距跟本一模一樣,且如果用組合語言設計會比用C語言還要不方便,哈哈就是強迫自己用C寫程式啦,附上一張照片我的LPC2103測試板,改天再陸續貼上我的程式
