Debian 13: configurating Syris RD200-M1-G v01.55 Card Reader Part 1, firmware upgrade

By default Syris RD200-M1-G v01.55 run in keyboard mode. It will send to text when card detected. 

You need to upgrade the firmware for support some new card and change it to com mode. At com mode, you can communication with card to utilize it.

DO THIS IN WINDOWS TO UPDATE FIRMWARE:

All documentation link provided by syris is https://syris.com/ftp/index.php. Goto SYRIS_RFID_DVD -> RD200_300 -> USB_ReaderTools
_V0291.rar (All tools and docs), download and extract. 

Inside RD200_RD300_SDK_V0193 -> UtilityTools -> FirmwareFiles, there are 2 directory v1 and v2:

• RD200(v1)
• RD200_M1_COM_V0271_20230901.SYB
• RD200_M1_V0271_20230901.SYB 
• RD200(v2)
• RD200-M1-V2_V0290_20250603.SYB
• RD200-M1-V2_V0291_20251029_01.SYB
• RD200-M1-V2-COM_V0283_20240216.SYB 

Run USB_ReaderTools_V0291_20251029.exe, go to tab firmware and use RD200_M1_COM_V0271_20230901.SYB to RD200-M1-G v01.55. If you choose wrong firmware, the tools will warn you "firmware type error". upgrade it, wait until finish.

After firmware upgraded, you need to change Auto Usb to Com, e.g. com3,(RD200-M1 0155) 12110056 -> (RD200-M1 0271) 12110056

Windows part is done.

This is Debian before upgrade and change to com mode

        Log.e("dedetok", "emojiGridColumns "+emojiGridColumns+" emojiGridRows "+emojiGridRows); // debug

 Note, you can remove *0.8f, in this context, the emoji only occupied 0.8 of finalHeight, not full. -1 is magic forcing internal emoji picker to reduce row and recalculate the emoji size.

lamp debian 13: configure codeigniter 4

Minimum codeigniter 4.7.2: php 8.2

Target access http://localhost/app1 

Download zip codeiginiter 4 from official site and extract into folder root e.g. /home/[username]/ci4/app1.

Install required php php-mbstring

# apt install php-intl php-mbstring
# systemctl restart apache2

The following PHP extensions should be enabled on your server:

• php-curl
• php-json
• php-mysqlnd/php-mysql
• php-imagick php-gd
• php-xml/php-simplexml

Default root folder

+-- app
+-- public
+-- tests
+-- spark
+-- system
+-- writable
|
+composer.json
+env
+LICENSE
+preload.php
+phpunit.xml.dist
+README.md

Change group and permission:

# usermod -a -G www-data [username]
# groups [username]
[username] : [username] cdrom floppy audio dip www-data video plugdev users netdev bluetooth lpadmin scanner libvirt
# chgrp www-data /home/[username] /home/[username]/ci4 /home/[username]/ci4/app1
# chmod g+x /home/[username] /home/[username]/ci4 /home/[username]/ci4/app1 

Edit /home/[username]/ci4/app1/app/Config/

<?php

namespace Config;

use CodeIgniter\Config\BaseConfig;

class App extends BaseConfig
{
    /**
     * --------------------------------------------------------------------------
     * Base Site URL
     * --------------------------------------------------------------------------
     *
     * URL to your CodeIgniter root. Typically, this will be your base URL,
     * WITH a trailing slash:
     *
     * E.g., http://example.com/
     */
    //public string $baseURL = 'http://localhost:8080/';
    public string $baseURL = 'http://localhost/app1/';

Option 1 Using subpath in user home folder

assume your root codeigniter is /home/[username]/ci4/app1

edit file /etc/apache2/sites-enabled/000-default.conf and restart

    <virtualhost>
	# The ServerName directive sets the request scheme, hostname and port that
	# the server uses to identify itself. This is used when creating
	# redirection URLs. In the context of virtual hosts, the ServerName
	# specifies what hostname must appear in the request's Host: header to
	# match this virtual host. For the default virtual host (this file) this
	# value is not decisive as it is used as a last resort host regardless.
	# However, you must set it for any further virtual host explicitly.
	#ServerName www.example.com

	ServerAdmin webmaster@localhost
	DocumentRoot /var/www/html

        # --- SUBPATH
        Alias /app1 /home/[username]/ci4/app1/public
        <directory app1="" ci4="" home="" public="" username="">
           Options Indexes FoolowSymLinks
           AllowOverride All
           Require all granted
        </directory>

~# apache2ctl configtest
AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1. Set the 'ServerName' directive globally to suppress this message
Syntax OK
~# systemctl restart apache2

No configuration in this option.

Option 2 Using subpath in copy public folder to /var/www/html/ 

this is close to shared web hosting

create folder app1 inside /var/www/html and move all content inside [ci4_project_root]/public  into app1

Edit file index.php

/*
 *---------------------------------------------------------------
 * BOOTSTRAP THE APPLICATION
 *---------------------------------------------------------------
 * This process sets up the path constants, loads and registers
 * our autoloader, along with Composer's, loads our constants
 * and fires up an environment-specific bootstrapping.
 */

// LOAD OUR PATHS CONFIG FILE
// This is the line that might need to be changed, depending on your folder structure.
//require FCPATH . '../app/Config/Paths.php'; // NOT USED
// ^^^ Change this line if you move your application folder 
// USE ABOSOLUTE PATH
require '/home/[username]/ci4/app1/app/Config/Paths.php'; 

You may do this in web shared hosting. the deference is /var/www/html and /home/[username]/public_html (usually in cpanel).

NOTE: choose one of the options above, don't mix it.

Using Sub domain e.g. app1.example.com (not tested)

Subdomain Method (Best Practice)

This is the cleaner and more secure method as it keeps the entire framework structure intact.

Steps:

1. Upload and extract your CodeIgniter zip into the folder you specified above e.g. /home/[username]/ci4/app1/.
2. In cPanel/Plesk, create a Subdomain (e.g., app1.domain.com).
3. Set its Document Root for sub domain to the public folder of your project (e.g., /home/[username]/ci4/app1/public) .
4. No code changes are needed. Your setup is complete.

For development, you can find file name env. Edit it, set CI_ENVIRONMENT = development (default is production), save it as .env (with . in leading file name).

 

Debian 13: configure php apache environment for personal development

Add user to group of www-data (this is example for CodeIgniter 4 Framework)

# usermod -a -G www-data [username]
# groups [username]
[username] : [username] cdrom floppy audio dip www-data video plugdev users netdev bluetooth lpadmin scanner libvirt
# chgrp www-data /home/[username] /home/[username]/ci4 /home/[username]/ci4/app1
# chmod g+x /home/[username] /home/[username]/ci4 /home/[username]/ci4/app1    

Folder structure for code igniter api

/home/[username]/ci4/app1

+-- tests
+-- spark
+-- system
+-- writable

+composer.json

+README.md    

Assume apache already installed, edit file /etc/apache2/sites-enabled/000-default.conf and add virtual folder e.g localhost/app1

    <virtualhost>
	# The ServerName directive sets the request scheme, hostname and port that
	# the server uses to identify itself. This is used when creating
	# redirection URLs. In the context of virtual hosts, the ServerName
	# specifies what hostname must appear in the request's Host: header to
	# match this virtual host. For the default virtual host (this file) this
	# value is not decisive as it is used as a last resort host regardless.
	# However, you must set it for any further virtual host explicitly.
	#ServerName www.example.com

	ServerAdmin webmaster@localhost
	DocumentRoot /var/www/html

        # --- SUBPATH
        Alias /app1 /home/[username]/ci4/app1/public
        <directory app1="" ci4="" home="" public="" username="">
           Options Indexes FoolowSymLinks
           AllowOverride All
           Require all granted
        </directory>

~# apache2ctl configtest
AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1. Set the 'ServerName' directive globally to suppress this message

Replace [username] with yours

Restart apache
