本人初学者, 习惯了 eclipse 的 IDE 环境做开发,如果用Eclipse来支持 Arduino 开发,就可以提供语法检查,函数索引,多项目管理了,甚至还可以用上git 这种高大上的代码管理工具,那将是多么美好的事儿啊 。因此,本人最近在网上找了许多资料尝试,终于成功。总结如下,与君共享。

==========================Part I. IDE开发配置===============================

1. 安装avrdude and AVR 库
Ubuntu下: >sudo apt-get install gcc-avr avr-libc avrdude
Windows下: 下载winavr进行安装,我的版本是WinAVR-20100110-install.exe (http://sourceforge.net/projects/winavr)

2. 安装CDT插件。打开Eclipse,选择Help -> Install New Software…,Work with 选择 Juno update site (如果没有,可以手工添加一个,地址用http://download.eclipse.org/releases/juno),然后选择 “Programming Languages” 下的 “C/C++ Development Tools” ,安装CDT插件。

3. 安装AVR Eclipse插件。选择Help -> Install New Software…,Work with 后的Add,在http中添加avr的源地址 "http://avr-eclipse.sourceforge.net/updatesite/", 等待下方出现avr插件,选择安装。

4. 下载linux 版本的Arduino SDK, "http://arduino.cc/en/Main/Software", 解压到Home下的某目录中(这里放在自建的OSS目录下,以下均按这个目录路径设置)
Windows下可将arduino开发包解压放于某个目录下(如 D:\arduino-0023),我用的版本是arduino-0023。记录该路径,后面的IDE环境配置需要用到。

5. 在eclipse中设定编译环境。在eclipse->Windows->reference,选择左侧AVR下的paths,
Ubuntu下:
*AVR-GCC:选择Edit,path source选择custom, custom value设为 /home/username/OSS/arduino-1.0.1/hardware/tools/avr/bin (username为用户名,需替换,以下同)
*AVR header files: 选择Edit,path source选择custom, custom value设为 /home/username/OSS/arduino-1.0.1/hardware/tools/avr/lib/avr/include
*AVR Dude: 选择Edit,path source选择custom, custom value设为 /home/username/OSS/arduino-1.0.1/hardware/tools
最后,点击apply,点击ok。
Windowns下:
如果WinAVR安装正确,Eclipse是可以自动发现 *AVR-GCC, * GNU make, * AVR header files的,如c:\WinAVR-20100110\bin,所以使用System的默认配置就好,如果没有默认配置,可以点击"Rescan"重新发现。
这里需要custom配置的是*AVR Dude,就是arduino开发包所在的路径,如D:\arduino-0023\hardware\tools\avr\bin

6. 建立avr的静态链接库。(可以通过git导入本空间下的ArduinoCore项目 https://gitlab.com/yeungbo/ArduinoPark/tree/master/ArduinoCore) 或者手工创建:在eclipse中选择new, 然后选择c++ project ->AVR Cross Target Static Library -> emtpy project,project名字为ArduinoCore,然后next,去掉debug的选择,将MCU Type” 和 “MCU Frequency” 设定为ATmega328P 和16MHz (16000000 Hz,6个零) (适合的板子是arduino uno和Arduino Duemilanove)。

7. 在eclipse,右键单击ArduinoCore,选择Properties->c/c++ build → settings -> avr compiler->directories 和 avr c++ compiler->directories,先后添加两个路径,
ubuntu中:
/home/username/OSS/arduino-1.0.1/hardware/arduino/variants/standard 和 /home/username/OSS/arduino-1.0.1/hardware/arduino/cores/arduino。
Windows中:
"D:\arduino-0023\hardware\arduino\cores\arduino" 和 "D:\arduino-0023\hardware\arduino\cores\arduino", 两者一样

8. 在eclipse中,选择ArduinoCore,创建一个arduino目录,在系统中找到 /home/username/OSS/arduino-1.0.1/hardware/arduino/cores/arduino,选择其下所有的文件,但去除main.cpp的选择。然后复制到ArduinoCore下新建的arduino目录中。
在windows中:选择 D:\arduino-0023\hardware\arduino\cores\arduino下所有的文件,但去除main.cpp。然后复制到ArduinoCore下新建的arduino目录中。

9. 最后选择ArduinoCore,选择build project,生成静态库libArduinoCore.a。

10. 创建测试项目。
导入本空间下的Blinky项目 https://gitlab.com/yeungbo/ArduinoPark/tree/master/Blinky
和上面的方法一样,将他导入eclipse,并把上面生成的 libArduinoCore.a 复制到这个工程中并且覆盖,然后就是配置编译参数了,只是更改几个路径而已,方法同上。最后 build(make all),成功编译,输出和上面的差不多,会在release目录中看到目标文件 Blinky.elf。剩下就是烧录了。

How to test a POP server by using telnet

How to test a POP server by using telnet

What you need

The host name of the POP server (for use in the telnet command)
The POP user name (for use in the USER command)
The user’s POP password (for use in the PASS command)


Encryption

For added security, you can encrypt your POP connection. This requires that your server supports SSL or TLS and that you have access to an SSL/TLS client program, for example OpenSSL, to use instead of telnet.

As the port number normally is 995, an example OpenSSL command would be openssl s_client -connect pop.example.com:995 -quiet. (If you would like to see the public key of the server, as well as some other encryption-related information, omit -quiet.) The server should then start a POP session, displaying a greeting such as the +OK InterMail POP3 server ready example below.


What to do

The DELE command flags messages for deletion. Use it only if you want to delete mail.

The initial telnet: > symbolises your shell prompt.

telnet: > telnet pop.example.com pop3
telnet: Trying 192.0.2.2...
telnet: Connected to pop.example.com.
telnet: Escape character is '^]'.
server: +OK InterMail POP3 server ready.
client: USER MyUsername
server: +OK please send PASS command
client: PASS MyPassword
server: +OK MyUsername is welcome here
client: LIST
server: +OK 1 messages
server: 1 1801
server: .
client: RETR 1
server: +OK 1801 octets
server: Return-Path: sender@example.com
server: Received: from client.example.com ([192.0.2.1])
server: by mx1.example.com with ESMTP
server: id <20040120203404.CCCC18555.mx1.example.com@client.example.com>
server: for <recipient@example.com>; Tue, 20 Jan 2004 22:34:24 +0200
server: From: sender@example.com
server: Subject: Test message
server: To: recipient@example.com
server: Message-Id: <20040120203404.CCCC18555.mx1.example.com@client.example.com>
server:
server: This is a test message.
server: .
client: DELE 1
server: +OK
client: quit
server: +OK MyUsername InterMail POP3 server signing off.

If you have a black screen with a messages like those :

>Windows could not start because the following file is missing or corrupt:
\WINDOWS\SYSTEM32\CONFIG\SYSTEM

>Windows NT could not start because the below file is missing or corrupt:
X:\WINNT\System32\Ntoskrnl.exe

>Windows NT could not start because the below file is missing or corrupt:
X:\WINNT\System32\HAL.dll

>NTLDR is Missing
Press any key to restart

>Invalid boot.ini
Press any key to restart

Repair with XP CD :
1. Boot with CDROM
2. Enter the installer XP CD
3. Press R if like this :

4. Press 1(or the other that show the installation drive) and enter the admin ]
Image

5. Type Like This :
> C: CD ..
> C: ATTRIB –H C:boot.ini
> C: ATTRIB –S C:boot.ini
> C: ATTRIB –R C:boot.ini
> C: del boot.ini
> C: BOOTCFG /Rebuild

6. After Rebuild finish type this:
C: CHKDSK /R /F kemudian
C: FIXBOOT
“Sure you want to write a new bootsector to the partition C: ?” press “Y”
C: EXIT
Enter

Hope this can be help you ..

儒略日的計算 
儒略日的計算

設Y為給定年份,M為月份,D為該月日期(可以帶小數)。
若M > 2,Y和M不變,若 M =1或2,以Y–1代Y,以M+12代M,換句話說,如果日期在1月或2月,則被看作是在前一年的13月或14月。
對格裡高利曆有 :A = INT(Y/100) B = 2 - A + INT(A/4)
對儒略曆,取 B = 0 More...
