Fireduino 网络万年历

前言
Fireduino 网络万年历是一个可以通过wifi联网，通过NTP协议获取到网络时间，并且使用RTC运行时钟以及万年历显示的示例，其中万年历可以显示从1583开始的公历以及星期，并且可以通过按键翻阅日历。
操作流程
上电后进行TFT初始化和WIFI初始化，进行WIFI连接并且在TFT上进行提示。
通过网络NTP协议获取网络时间，并且写入到RTC中，如果NTP获取失败，将在星期右侧显示字符“-_-||”表示同步失败，下次同步成功后可以消除该状态。
进入“时钟”界面，在TFT上显示表盘、星期、日期以及时间。
短按按Mode键同步NTP网络时间。
长按Mode键后循环切换主显示界面，主要有"时钟"界面、"本月日历"界面以及"翻阅万年历"界面。
"本月日历"界面显示年份、月份以及本月日历（包含星期）以及高亮显示今日位置，无切换界面外的按键响应。
“翻阅万年历”界面可以通过按键翻阅日历。短按MODE 切换位，短按UP、DOWN调相应值，长按快速UP、DOWN调相应值。
硬件连接
Fireduino
Fireduino 作为主MCU，为驱动TFT、RTC、KEY等提供逻辑运行环境。
TFT
TFT 为显示设备，主要提供显示表盘以及时间字符、日历显示。
RTC
RTC 是板载的RTC独立单元，用于保存和获取实时时间，使用的为HYM8563，挂载在I2C1 接口，Fireduino 为此提供了专门的RTC库可供直接使用。
按键
按键用于修改切换显示界面、同步NTP时间以及浏览日历。
软件逻辑
界面
网络万年历主要分为如下几个界面
// status of display#define MODE_DISPLAY_TIME 0 //显示表盘、今日星期、日期以及时间#define MODE_DISPLAY_CAL 1 //显示本月日历#define MODE_BROWSE_CAL 2 //翻阅日历
事件
事件由按键触发，为事件处理提供依据
#define EVENT_MODE 1 //模式键抬起事件#define EVENT_UP 2 // UP事件 #define EVENT_DOWN 3 // DOWN事件#define EVENT_MODE_CHANG 4 // 模式改变时间#define EVENT_MODE_CLICK 5 //模式键按下事件
按键处理
本示例使用了3个按键，使用了pin 5、6、7，每20ms 扫描一次按键状态，支持长按和短按。
按键扫描
每20ms扫描一次。
void key_sacn(void){unsigned char pin_level = 0;if(digitalRead(5) == HIGH){
pin_level |= KEY_MODE;}if(digitalRead(6) == HIGH){
pin_level |= KEY_UP;}if(digitalRead(7) == HIGH){
pin_level |= KEY_DOWN;}
key_trg = pin_level&(pin_level^key_count);
key_count = pin_level;}按键处理
根据状态，生成事件
void key_proc(void){if(key_trg & KEY_UP){
event_key = EVENT_UP ;} if(key_count & KEY_UP){
up_count++;if(up_count > 100){
up_count = 80 + up_count_i;if(up_count_i++ >100){
up_count_i = 100;}
event_key = EVENT_UP;}}else{
up_count = 0;
up_count_i = 0;} }显示处理
根据不同模式，显示不同界面。
MODE_DISPALY_TIME 模式显示时钟表盘及今日星期、日期和时间。
MODE_DISPALY_CAL 模式显示本月日历，显示年份、月份、星期以及高亮显示今日日期位置。
MODE_BROWSE_CAL 模式显示可翻阅的日历，可修改年份和月份，修改的位会相应的闪烁。
事件处理
事件处理在按键处理之后，根据时间对于不同的处理。
void event_proc(void){if(event_key){switch(event_key){case EVENT_MODE :.....break;case EVENT_UP :.....
break;case MODIFY_HOUR :..... break;case EVENT_DOWN :..... break;case EVENT_MODE_CHANG :..... break;} event_key = 0;}}绘图处理
void clear_all(void); //清除整个屏幕void clear_dial(void); //清除表盘void clear_time_pointer(void); //清除表指针void clear_time_txt(unsigned char flash_bit); //清除时钟界面显示的文本void draw_dial(void); //绘制表盘void draw_time_pointer(RTCTime *time); //绘制表指针void draw_time_txt(RTCTime *time); //绘制时钟界面显示文本void draw_cal(RTCTime *time); //绘制今日日历void draw_browse_cal(RTCTime *time); //绘制可翻阅日历
