Two years ago, something, tidy up, maybe later will be used.

Arm for the s3c2440 of this arm-driven finishing.

These include: Adc,beeper buzzer, key key, RTC, timer timer, UART driver.

****************
This is the ADC driver.

#include"s3c2440.h"#if0voidNiuniu (void) {uart_init ();    Adc_init ();    Adc_read ();  while(1) {itoa (Adc_read ()); Delay (10000); }}#endif#ifAdstart==0voidNiuniu (void) {uart_init ();    Adc_init ();    Beeper_init ();    Adc_read ();  while(1) {itoa (Adc_read ()); if(Adc_read () >2500) {beeper_on (); }        Else{Beeper_off (); } Delay (10000); }}#endif#ifAdstart==1voidNiuniu (void) {uart_init ();    Adc_init ();    Beeper_init ();  while(1) {adc_enable ();        Itoa (Adc_read ()); if(Adc_read () >2500) {beeper_on (); }        Else{Beeper_off (); } Delay (10000); }}#endif

********************
Driver for buzzer:

#include"s3c2440.h"#if0voidNiuniu (void) {beeper_init ();  while(1) {beeper_on (); Delay (10000);        Beeper_off (); Delay (10000); }}#endif#if1voidNiuniu (void) {key_init ();    Beeper_init ();  while(1)    {        if(Key_on ( One) ==1) {beeper_on (); }        Else{Beeper_off (); }    }}#endif

***************************
This is the key driver.

#include"s3c2440.h"#if0//key wheel Patrol modevoidNiuniu (void) {led_init ();    Key_init ();  while(1)    {        if(Key_on (5) ==1) {led_on (1); }        Else{Led_off (1); }    }}#endif#if1//Key Interrupt ModevoidNiuniu (void) {beeper_init ();    Key_init ();    Extint_init ();    Int_init ();    Uart_init ();  while(1) {puts ("Key int mode\r\n"); Delay ( +); }}#endif

**************************
This is the LED light driver:

 #include  s3c2440.h   " void  Niuniu (void  ) {Led_init ();  while  (1   2  );        led_on ( 4  );        Delay ( 10000  );        Led_off ( 2  );        Led_off ( 4  );    Delay ( 10000  ); }}

This is the RTC driver.

#include"s3c2440.h"#include<string.h>#include<stdlib.h>#if0voidNiuniu (void){    inttime[7]; Charbuf[ +], *p[9]; inti;        Uart_init ();  while(1) {puts ("\r\nrtc>");        Gets (BUF); Buf[strlen (BUF)-2] =' /'; p[0] = Strtok (buf," ");  for(i=1; p[i-1]!=null; i++) {P[i]= Strtok (NULL," "); }        if(strcmp (p[0],"Timeset") ==0) {time[0] = Atoh (p[1]); time[1] = Atoh (p[2]); time[2] = Atoh (p[3]); time[3] = Atoh (p[4]); time[4] = Atoh (p[5]); time[5] = Atoh (p[6]); time[6] = Atoh (p[7]);        Rtc_init (time); }        if(strcmp (p[0]," Time") ==0) {rtc_display (); }    }}#endif#if1voidNiuniu (void) {uart_init ();    Int_init ();    Alarm_init ();    Beeper_init ();  while(1) {rtc_display (); Sleep (1); }}#endif

This is the driver of the timer:

" s3c2440.h " void Niuniu (void) {    int_init ();    Timer_init ();    Beeper_init ();    Uart_init ();    Timer_update ();      while (1)    {        puts ("haha ... \ r \ n");        Sleep (1);}    }

This is the driver for the UART timer:

#include"s3c2440.h"#include<string.h>#if0voidNiuniu (void){    Charbuf[ +];    Uart_init ();  while(1) {puts ("Send:");        Gets (BUF); Puts ("\NRECV:");    Puts (BUF); }}#endif#if1voidNiuniu (void){    Charbuf[ -]; Char*p[6]; inti;    Beeper_init ();    Led_init ();    Uart_init ();  while(1) {puts ("\r\nuart>");        Gets (BUF); //remove \ r \ nBuf[strlen (BUF)-2] =' /'; //The strtok function uses global variablesp[0] = Strtok (buf," ");  for(i=1; p[i-1]!=null; i++) {P[i]= Strtok (NULL," "); }        if(strcmp (p[0],"LeDon") ==0)        {            if(strcmp (p[1]," All") ==0)            {                 for(i=1; i<5; i++) {led_on (i); }            }            Else            {                 for(i=1; P[i]!=null; i++) {led_on (*p[i]- -); }            }        }        if(strcmp (p[0],"Ledoff") ==0)        {            if(strcmp (p[1]," All") ==0)            {                 for(i=1; i<5; i++) {Led_off (i); }            }            Else            {                 for(i=1; P[i]!=null; i++) {Led_off (*p[i]- -); }            }        }        if(strcmp (p[0],"Beeperon") ==0) {beeper_on (); }        if(strcmp (p[0],"Beeperoff") ==0) {Beeper_off (); }    }}#endif
