Eclipse Mosquitto Windows hakkında

 Merhaba bu yazıyı gelecekte aynı saçmalıkları ben veya başka bir insan yapmasın diye yazıyorum.

Eclipse Mosquitto tamamen ücretsiz ve windows'tada çalışıyor

1. İlk olarak mosquitto programını indermek gerekiyor. aşağıdaki linkten indirin.

https://mosquitto.org/download/

2. burada tam olarak yükleme, windows path'e ekleme işlemlerini vb. anlatıyor. ama iş bitmiyor.

3. kullanıcı ve şifre yaratmayı bu siteden bak ve yap çalışıyor.

4. C:\Program Files\mosquitto bu klasör içinde özel olarak konfigürasyonları yapabileceğiniz ayarlar.conf diye bir dosya üretiyorsunuz.

Ben user name ve password'lü bağlantı istediğimden şunları ekledim.

listener 1883
allow_anonymous false
password_file C:\Program Files\mosquitto\p2.txt

Bitti mi hayır :)

4. bu konfügürasyonu window çalıştırmak için cmd'den (cmd admin olarak aç);

mosquitto -v -c ayarlar.conf 

 yazarak ayarlar içindeki 3 parametreye göre mosquitto servisini çalışır hale getir.

NOT: servis çalışıp çalışmadığı o anda zaten belli oluyor.

Bitti :) 

 

 

c# program.exe.configuration

 When you need save and read some parameters which related about your settings or something else;

1. If your project does not have a "App.config" file; to make new one, right click  your project and "Add->New Item->App Configuration File".

2. Open "App.Config" file and view your file like that;

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <configSections>
    <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System">
      <section name="DevExpress.LookAndFeel.Design.AppSettings" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false"/>
    </sectionGroup>
  </configSections>
  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.8"/>
  </startup>
	<appSettings>
		<add key="deviceModel" value="0" />
	</appSettings>
</configuration>

This is a code snippet for read value and change and save procedure;

var appSettings=ConfigurationManager.AppSettings;
if (appSettings["deviceModel"].Length!=0)
{
    textBox1.Text = appSettings["deviceModel"].ToString();
}

int tempVal;
var configFile = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
var settings = configFile.AppSettings.Settings;
if (settings["deviceModel"] == null)
{
    settings.Add("deviceModel", "1");
}
else
{
    tempVal = int.Parse(settings["deviceModel"].Value);
    tempVal++;
    settings["deviceModel"].Value = tempVal.ToString();
}
configFile.Save(ConfigurationSaveMode.Modified);
ConfigurationManager.RefreshSection(configFile.AppSettings.SectionInformation.Name);

Keil MDK Arm

 Merhaba bu sayfada Keil'de karşılaştığım bazı sorun ve çözümleri paylaşacağım.

1. Keil StLink yüzünden kendi kendine çöktüğü zamanlar oluyor bunun için buradaki linkten signed driver'ı indirip. "C:\Keil_v5\ARM\STLink" klasörünün altındaki "STLinkUSBDriver.dll" --> sonuna backup yazıp("STLinkUSBDriver.dll_backup") yedekledikten sonra indirdiğiniz dosyayı buraya kopyalayın sorun çözülmüş olacak.

Harmonics(in electrical systems)

• https://www.fluke.com/en/learn/blog/power-quality/how-to-find-harmonics-in-electrical-systems
  
•  Overheated transformers and tripped breakers could be a sign of harmonic issues, which occur when non-linear loads that draw current in abrupt pulses, rather than in a smooth sinusoidal manner, cause harmonic currents to flow back into other parts of the power system.
• This value of THD in terms of power quality health is most often applied to the voltage. Guidance states that the voltage harmonic effects should be less than 8 percent relative to the fundamental. Values above the stated 8 percent should be investigated further.

 

This document solution is the best approach.

PowerFactor VS CosPhi

You Can read this article. In summary;

• CosPhi results from the ratio of effective power (P) to fundamental apparent power (S1). 

• PF; results from the ratio of effective power (P) to total apparent power (S) from fundamental and harmonics.
  

 

Beaglebone Black Notes

1. When you need enabling uart of beaglebone black. read this site first and read this site

      2. Minicom is a great tool for command line serial port testing.

    " minicom -b 9600 -D /dev/ttyO1" --> 9600 8N1 open Uart1 BBB :)

Altium Designer Notes

1.  Q --> change to imperial to mm or reverse is true
2. TAB --> open properities panel
3. After selecting the component, press the left key of the mouse and click the J+R character on your keyboard. This shortcut helps to which you select things and move to the center.  
4. CTRL+M --> Measurement , SHIFT+C clear measurements value view. 
5. Press G character to change grid size.
6. Place->Directives->No ERC for closing unused pins
7. ON/OFF  if you want to top line to "ON" a straight line, use this technique.
   

 

Note: when you need a specific shortcut about Altium Designer. please see this video for remembering something.

c# Notes

• The fact that in Fig. 4.1 we could create and manipulate an Account object without knowing its implementation details is called abstraction. This is one of the most powerful software-engineering benefits of object-oriented programming
• https://www.w3schools.com/cs/cs_properties.php
• If you declare one or more constructors for a class, the compiler will not create a default
  constructor for that class.

CTRL+A then CTRL+K+F code auto align
