1.Overview

本文针对tiny6410裸机程序中的Led、Button、Timer、Interrupt 等控制程序进行分析，部分代码由国嵌相关代码修改得到。

（PS:需安装好jlink和rvds2.2，对于代码中所有include到的文件可以在Reference中找到）

2.Led

（1）Tiny6410核心板的LED1、LED2、LED3、LED4分别连接到了GPK4、GPK5、GPK6、GPK7。电路图如下：

（2）led.h

使用 #ifndef __LED__ 来避免重复的包含文件（每个头文件都建议加上）
module_cfg.h 里进行了模块名的定义 #define LED
使用#ifdef LED判断是否已经定义模块，已经定义则使宏定义和函数声明有效（配合module_cfg.h可以方便的关闭对应的模块，减少不必要的编译）

#ifndef __LED__#define __LED__#include "module_cfg.h"#ifdef LED/**************Macro Definition**********/#define LED1_ON   ~(1<<4)#define LED2_ON   ~(1<<5)#define LED3_ON   ~(1<<6)#define LED4_ON   ~(1<<7)#define LED1_OFF   (1<<4)#define LED2_OFF   (1<<5)#define LED3_OFF   (1<<6)#define LED4_OFF   (1<<7)#define LEDALL_OFF (0xf<<4)/**************Declare Function**********/void LedDelay(int times);void LedPortInit(void);void LedRun(void);#endif#endif

（3）led.c

LedDelay 只为简单的延时函数，需要准确的计时可查看Timer章节
LedPortInit 为初始化对应的GPIO为输出模式（翻查s3c6410芯片手册的GPK寄存器可知）
LedRun 为流水灯程序，根据LED电路图可知：IO输出为低电平时，LED点亮；IO输出为高电平时，LED熄灭

#include "module_cfg.h"#ifdef LED#include "def.h"#include "led.h"#include "gpio.h"/************************************************************************* * ***************************延时函数************************************ * ***********************************************************************/void LedDelay(int times){    int i;    for(;times>0;times--)      for(i=0;i<3000;i++);}/************************************************************************* **********************初始化连接LED灯的管脚资源************************** * @ 通过将GPIO_BASE强制转化为(volatile oGPIO_REGS*)型的指针可以很方便 * 的访问各个GPIO寄存器的值，这种方法比通过使用寄存器地址的宏定义访问 * 寄存器单元更加规范和科学。 * ***********************************************************************/  void LedPortInit(void){u32 uConValue;uConValue = GPIO->rGPIOKCON0;uConValue &= ~(0xffff<<16);uConValue |= 0x1111<<16;GPIO->rGPIOKCON0 = uConValue;GPIO->rGPIOKDAT|=LEDALL_OFF;}/************************************************************************* * ************************跑马灯的实现函数******************************* * @ 通过控制连接LED的管脚的输出电平点亮和熄灭各个LED。 * @ 逐个循环点亮各个LED。在每点亮一个后保持一定时间再熄灭它，接着 * 点亮下一个LED，这样就形成了一个跑马灯的效果。 * @ 这是一个需要改善的跑马灯程序，想想怎么优化这段代码。 * ***********************************************************************/void LedRun(void){    GPIO->rGPIOKDAT |= LEDALL_OFF;    while(1){GPIO->rGPIOKDAT &= LED1_ON;LedDelay(1000);GPIO->rGPIOKDAT |= LEDALL_OFF;GPIO->rGPIOKDAT &= LED2_ON;LedDelay(1000);GPIO->rGPIOKDAT |= LEDALL_OFF;GPIO->rGPIOKDAT &= LED3_ON;LedDelay(1000);GPIO->rGPIOKDAT |= LEDALL_OFF;GPIO->rGPIOKDAT &= LED4_ON;LedDelay(1000);GPIO->rGPIOKDAT |= LEDALL_OFF;    }}#endif

3.Button

（1）Tiny6410底板按键button1~8 分别连接到GPN0~5、GPL11、GPL12，电路图如下：

(2)使用轮循方式实现按键识别

设置GPN0~3 为输入
轮循GPNDAT判断按键是否按下
GPN0~3 对应LED1~4,按键按下时，对应的LED会被点亮

led_io.h

#ifndef __KEY_IO__#define __KEY_IO__#include "module_cfg.h"#ifdef KEY_IO/**************Macro Definition**********/#define LED1_ON   ~(1<<4)#define LED2_ON   ~(1<<5)#define LED3_ON   ~(1<<6)#define LED4_ON   ~(1<<7)#define LEDALL_OFF (0xf<<4)/**************Declare Function**********/void KeyIoPortInit(void);unsigned int CheckKeyStat(void);void KeyIoTest(void);#endif#endif

led_io.c

#include "module_cfg.h"#ifdef KEY_IO#include "def.h"#include "key_io.h"#include "gpio.h"/************************************************************************* * ***************************按键IO初始化******************************** * ***********************************************************************/void KeyIoPortInit(void){GPIO->rGPIONCON&=0xffffff00;}/************************************************************************* * ***************************检测按键状态******************************** * ***********************************************************************/unsigned int CheckKeyStat(void) { if((GPIO->rGPIONDAT&0x1)==0)return 1; else if((GPIO->rGPIONDAT&0x2)==0)return 2; else if((GPIO->rGPIONDAT&0x4)==0)return 3; else if((GPIO->rGPIONDAT&0x8)==0)return 4; return 0; }  /************************************************************************* * ***************************按键测试程序********************************* * ***********************************************************************/ void KeyIoTest(void) { unsigned int j; while(1){j=0;j=CheckKeyStat();switch(j){case 1:GPIO->rGPIOKDAT |= LEDALL_OFF;GPIO->rGPIOKDAT &= LED1_ON;break;case 2:GPIO->rGPIOKDAT |= LEDALL_OFF;GPIO->rGPIOKDAT &= LED2_ON;break;case 3:GPIO->rGPIOKDAT |= LEDALL_OFF;GPIO->rGPIOKDAT &= LED3_ON;break;case 4:GPIO->rGPIOKDAT |= LEDALL_OFF;GPIO->rGPIOKDAT &= LED4_ON;break;default :break;}} }#endif

(3）使用中断方式识别按键

The interrupt controller in the S3C6410X is composed of 2 VIC’s (Vectored Interrupt Controller, ARM PrimeCell PL192) and 2 TZIC’s (TrustZone Interrupt Controller, SP890).
Two TZIC’s and VIC’s are daisy-chained to support up to 64 interrupt sources. （可以查看s3c6410芯片手册看到对应的64个中断源）

GPN0~3对应中断源为INT_EINT0，该中断源对应了三个中断信号（External interrupt 0 ~ 3 ）
程序入口需要Enable VIC、Enable IRQ、Disable All INT（可查看Reference里面的main.c）

主要配置流程如下

设置GPN0~3为外部中断模式（GPNCON），禁止上拉下拉电阻（GPNPUD），配置中断方式为GPN0、1为低电平触发，GPN2、3为上升沿触发（EINT0CON0）
清除对应的中断悬起位（EINT0PEND）
配置中断服务地址程序（VIC0VECTADDR）
使能中断源（VIC0INTENABLE）
清除中断屏蔽位（EINT0MASK）

具体代码如下：

key_int.h

#ifndef __KEY_INT__#define __KEY_INT__#include "module_cfg.h"#ifdef KEY_INT/**************Macro Definition**********/#define LED1_ON   ~(1<<4)#define LED2_ON   ~(1<<5)#define LED3_ON   ~(1<<6)#define LED4_ON   ~(1<<7)#define LEDALL_OFF (0xf<<4)/**************Declare Function**********/void KeyIntPortInit(void);void __irq Key_Eint(void);void KeyEintInit(void);void EINT0ClrPend(u32 uEINT_No);void EINT0DisMask(u32 uEINT_No);#endif#endif

4.Timer

（1）s3c6410定时器概述

The S3C6410X RISC microprocessor comprises of five 32-bit timers. These timers are used to generate internal interrupts to the ARM subsystem. In addition, Timers 0 and 1 include a PWM function (Pulse Width Modulation), which can drive an external I/O signal. The PWM for timer 0 and 1 have an optional dead-zone generator capability, which can be utilized to support a large current device. Timer 2, 3 and 4 are internal timers with no output pins.

一般的配置流程如下：

程序入口需要Enable VIC、Enable IRQ、Disable All INT（可查看Reference里面的main.c）
停止所有的定时器（TCON）
配置定时器：获取g_PCLK，设置Prescaler（TCFG0），设置MUX（TCFG1），设置TCNTBn。（主要配置了定时器产生中断间隔，如果需要输出PWM，需要配置TCMPBn，同时使能PWM输出）
清除中断悬起位（TINT_CSTAT）
配置中断服务程序地址（VIC0VECTADDR+NUM_TIMERn*4）
使能对应中断源（VIC0INTENABLE）
清除中断屏蔽位（TINT_CSTAT）
启动定时器（TCON）
