Microduino-RTC小应用：网络时钟+OLED显示
本帖最后由 wasdpkj 于 2013-8-29 00:41 编辑[关于microduino上架问题：老张和tiki最近都很忙，过些天应该会陆续上架，需要模块的朋友耐心等等]
------------------------------------------------------------
关于Microduino-RTC模块：
Microduino-RTC模块是基于 PCF8563芯片的时钟模块，模块还附加AT24c32芯片，提供额外的EEPROM功能。I2C接口通信。 采用电容提供了一定的掉电计时能力。PCF8563使用一个外部晶体和电容，并有1个中断输出，可以定时触发中断。
更详细信息：http://wiki.microduino.net/wiki/Microduino-RTC
关于RTC等I2C模块适配Core+：
Core+的IIC接口和Core的不一样，不是A4和A5，而是D20（SDA）和D21（SCL），请注意引出。
先看看如何驱动RTC模块：
首先我们来设置时间，我在源程序“set_clock”的基础上加以修改，时间的两个格式都调用出来。（源程序setup里少了一行串口初始化 Serial.begin(9600);）
#include <Wire.h>
#include <Rtc_Pcf8563.h>
//init the real time clock
Rtc_Pcf8563 rtc;
void setup()
{
Serial.begin(9600);
//clear out the registers
rtc.initClock();
//set a time to start with.
//day, weekday, month, century(1=1900, 0=2000), year(0-99)
rtc.setDate(29, 4, 8, 0, 13);
//hr, min, sec
rtc.setTime(00, 21, 0);
}
void loop()
{
//both format functions call the internal getTime() so that the
//formatted strings are at the current time/date.
Serial.println("CODE_1:");
Serial.print(rtc.formatTime());
Serial.print(" ");
Serial.print(rtc.formatDate());
Serial.print("\r\n");
Serial.println("CODE_2:");
Serial.print("20");
Serial.print(rtc.getYear());
Serial.print("/");
Serial.print(rtc.getMonth());
Serial.print("/");
Serial.print(rtc.getDay());
Serial.print(" ");
Serial.print(rtc.getHour());
Serial.print(":");
Serial.print(rtc.getMinute());
Serial.print(":");
Serial.print(rtc.getSecond());
Serial.print("\r\n");
delay(1000);
Serial.print("\r\n");
}
}
运行效果：

接下来简单介绍一下标题所指的应用：
主要功能：开机自动获取DHCP，获取网络NTP时间，如果成功则会将时间同步到Pcf8563里。加以OLED显示。
硬件用到了：
Microduino-Core+、Microduino-FT232R、【Microduino-ENC28J60】 + 【Microduino-RJ45】、Microduino-OLED、Microduino-RTC。
程序如下：

//-------字体设置，大、中、小
#define setFont_L u8g.setFont(u8g_font_7x13)
#define setFont_M u8g.setFont(u8g_font_fixed_v0r)
#define setFont_S u8g.setFont(u8g_font_chikitar)
/*

等上架了，我也搞套microduino玩玩:lol 应该可以摞起来吧? ogre_c 发表于 2013-8-29 04:58 static/image/common/back.gif
看见了老潘风骚的3d打印板 万事具备就差RTC了。
:lol偷懒，直接当oled扩展板用了 :Q这小板，没得方买呀，哪里购的? wyd1520 发表于 2013-8-29 13:55 static/image/common/back.gif
这小板，没得方买呀，哪里购的?
看文末链接 OLCD可以图形吧,可以将时钟显示大些就漂亮了. 请问28J60网络模块怎么接线呢？ 504835618 发表于 2014-10-3 20:24 static/image/common/back.gif
请问28J60网络模块怎么接线呢？
用Microduino模块 直接堆叠就行~不用连线
