Hex String to Integer C/C++

How to convert a C/C++ hex string to integer?

There are no standard ansi functions to perform the data conversion from a hex string to integer.

The atoh function here listed can easily convert an Hex String to Integer.

int atoh(char * string, int size, bool reverse)
{
//By www.oldwildweb.com
unsigned int value = 0;
int char_val = 0;
int hchar_val = 1;

if (reverse == true)
for (int i = 0; i < size; i++)
{
if (string[i] == '0')
char_val = 0;
if (string[i] == '1')
char_val = 1;
if (string[i] == '2')
char_val = 2;

char_val = 14;
if (string[i] == 'f' || string[i] == 'F' )
char_val = 15;

value = value + (hchar_val*char_val);
hchar_val *= 16;
}
else
for (int i = size-1; i >= 0; i--)
{
if (string[i] == '0')
char_val = 0;
if (string[i] == '1')
char_val = 1;
if (string[i] == '2')
char_val = 2;

if (string[i] == 'e' || string[i] == 'E' )
char_val = 14;
if (string[i] == 'f' || string[i] == 'F' )
char_val = 15;

Php max get length

Apache and Php max get lenght

 By kingk (art. no 16)

Php max get length - Apache max Get Lenght

The max lenght of a GET variable is setted to 512 Bytes/Variable by default in all Php 5.x versions, while most browsers can support huge urls (with more than 2048 bytes depending on the browser version).

To change the max get lenght parameter you can edit the related configuration file of Php5 under:

/etc/php5/apache2/conf.d/suhosin.ini

The lenght parameter is definited by the string:

suhosin.get.max_value_length = 512

The standard http url size is at least 8096 bytes, but most servers can use more.

Warning session_start(): cannot send session cookie headers already sent by output started at

Common PHP errors

 By kingk (art. no 15)

Warning session_start(): cannot send session cookie headers already sent by output started at ...

This is one of the most common Warnings with CMS installations.

-Do not leave blank space or chars before the ?php tag

-Don't use the ASCII file transfer mode with your FTP client, use the Binary mode instead.

How to enable the gpio_dev driver with FOX board G20 and the linux kernel 2.6.38.3

 By kingk (art. no 14)

FOX G20 gpio_dev Driver for kernel 2.6.38.3

This patch enables the gpio_dev driver in new Linux Kernels, the new driver use the unlocked_ioctl method instead of the old ioctl method (removed in new kernels), for more information about how the driver works visit the Acme System Gpio tutorial page (to use the patch in kernels newer than 2.6.38.3, replace the string: "2.6.38.3" with the correct kernel version in the patch file with any text editor).

Linux commands

Download the kernel src

wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.38.3.tar.bz2

Extract the archive:

tar xvjf linux-2.6.38.3.tar.bz2

Open the kernel src folder

cd linux-2.6.38.3

Download the patch

wget http://www.oldwildweb.com/public/downloads/en/Linux/gpio-dev-kernel-patch-2.6.38.3

Apply the Patch

patch -p1 < gpio-dev-kernel-patch-2.6.38.3

Follow the Acme System Kernel compile tutorial: http://foxg20.acmesystems.it/doku.php?id=tutorial:compiling_the_linux_kernel_2.6.38.

Remember to Enable the GPIO Device as static module in the kernel configuration under: Device Drivers-> GPIO Support -> GPIO device support.

To avoid to recompile the kernel you can use the uImage and the lib files to upgrade your fox G20 SD.

Replace your uImage file with the new one in the kernelfs partition of your Fox G20 SD.

Replace all files under the /lib folder of the rootfs partition with new files.

On the next Fox G20 boot don't forget to use the comand

depmod -a

Kernel features:
-FAT32, NTFS, BTRFS, EXT2, EXT3, EXT4, ReiserFS and all other File System support.

-Moxa Uport1450 USB to 4 RS-232/422/485 devices (driver compiled as static module).

Radiations conversion table

Radiations units, conversion table mRem REM to Sievert

 By kingk (art. no 12)

Radiation unit conversion table From mREM REM to Sievert


The Japanese nuclear disaster is a threath for all the countries that could be invested by radiation particles.

The only way to monitor the nuclear threath is the geiger counter: a type of particle detector that measures ionizing radiation. In order to use a Geiger counter you must be aware about radiation's measurement units. The standard is the Sievert.
The safe threshold for humans is of 80mREM/H or 800 uSv/h.



xSv 0.1 uSv 1 uSv 10 uSv 100 uSv
xREM 0.01 mrem 0.1 mrem 1 mrem 10 mrem
xSv 1 mSv 10 mSv 100 mSv 1 Sv
xREM100 mrem 1 rem 10 rem 100 rem

A Java Modbus server on TCP/IP example

Multi-client multi-thread Java Modbus Server on TCP IP example by Ugo Cirmignani

 By kingk (art. no 8)

The Modbus is a simple and free industrial protocol, there is an official (and very good) documentation about the protocol but there are no so many examples of how implement a Modbus server on tcp/ip.

In this article we provide a simple class to create a Java Modbus server on TCP/IP capable to use the Read Holding Register function.

The "Read Inputs Register" function can be used to read data from a Modbus server with a Modbus client, each register is composed of 2 bytes of data (by standard each register is a 16bit integer).

To use the class consider this example:

package simpleserver;
public class Main
{
public static void main (String args[])
{
try
{
ModbusServer mbs = new ModbusServer(502);
Thread t = new Thread (mbs);
t.start();
while (true)
{
System.out.println("The server is running..");
Thread.currentThread().sleep(10000);//sleep for 1000 ms
}
}
catch (Exception ex)
{
}
}
}
