1.Overview
本文針對tiny6410裸機程序中的Led、Button、Timer、Interrupt 等控制程序進行分析，部分代碼由國嵌相關代碼修改得到。
（PS:需安裝好jlink和rvds2.2，對於代碼中所有include到的文件可以在Reference中找到）
2.Led
（1）Tiny6410核心板的LED1、LED2、LED3、LED4分別連接到了GPK4、GPK5、GPK6、GPK7。電路圖如下：
（2）led.h
- 使用 #ifndef __LED__ 來避免重複的包含文件（每個頭文件都建議加上）
- module_cfg.h 裏進行了模塊名的定義 #define LED
- 使用#ifdef LED判斷是否已經定義模塊，已經定義則使宏定義和函數聲明有效（配合module_cfg.h可以方便的關閉對應的模塊，減少不必要的編譯）
#ifndef __LED__
#define __LED__
#include "module_cfg.h"

#define LED2_OFF (1<<5)
#define LED3_OFF (1<<6)

#define LEDALL_OFF (0xf<<4)
/**************Declare Function**********/
void LedDelay(int times);
void LedPortInit(void);
void LedRun(void);
#endif
#endif（3）led.c
- LedDelay 只爲簡單的延時函數，需要準確的計時可查看Timer章節
- LedPortInit 爲初始化對應的GPIO爲輸出模式（翻查s3c6410芯片手冊的GPK寄存器可知）
- LedRun 爲流水燈程序，根據LED電路圖可知：IO輸出爲低電平時，LED點亮；IO輸出爲高電平時，LED熄滅

3.Button
（1）Tiny6410底板按鍵button1~8 分別連接到GPN0~5、GPL11、GPL12，電路圖如下：
(2)使用輪循方式實現按鍵識別
- 設置GPN0~3 爲輸入
- 輪循GPNDAT判斷按鍵是否按下
- GPN0~3 對應LED1~4,按鍵按下時，對應的LED會被點亮

(3）使用中斷方式識別按鍵
- 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芯片手冊看到對應的64箇中斷源）
- GPN0~3對應中斷源爲INT_EINT0，該中斷源對應了三個中斷信號（External interrupt 0 ~ 3 ）
- 程序入口需要Enable VIC、Enable IRQ、Disable All INT（可查看Reference裏面的main.c）
主要配置流程如下
- 設置GPN0~3爲外部中斷模式（GPNCON），禁止上拉下拉電阻（GPNPUD），配置中斷方式爲GPN0、1爲低電平觸發，GPN2、3爲上升沿觸發（EINT0CON0）
- 清除對應的中斷懸起位（EINT0PEND）
- 配置中斷服務地址程序（VIC0VECTADDR）
- 使能中斷源（VIC0INTENABLE）
- 清除中斷屏蔽位（EINT0MASK）
具體代碼如下：

4.Timer
（1）s3c6410定時器概述
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裏面的main.c）
- 停止所有的定時器（TCON）
- 配置定時器：獲取g_PCLK，設置Prescaler（TCFG0），設置MUX（TCFG1），設置TCNTBn。（主要配置了定時器產生中斷間隔，如果需要輸出PWM，需要配置TCMPBn，同時使能PWM輸出）
- 清除中斷懸起位（TINT_CSTAT）
- 配置中斷服務程序地址（VIC0VECTADDR+NUM_TIMERn*4）
- 使能對應中斷源（VIC0INTENABLE）
- 清除中斷屏蔽位（TINT_CSTAT）
- 啓動定時器（TCON）
