NEX is an open extension format from Opera Software

Senior Technology Writer

Someone sent you a e-mail NEX file and you don't know how to open it? Maybe you found a NEX file on your computer and were wondering what it was? Windows may tell you that you cannot open it, or in the worst case, you may encounter a corresponding error message associated with the NEX file.

Before you can open a NEX file, you need to find out what kind of file the NEX file extension is.

Tip: Incorrect NEX file association errors can be a symptom of other underlying issues within your Windows operating system. These invalid entries can also produce associated symptoms such as slow Windows startups, computer freezes, and other PC performance issues. Therefore, it is highly recommended that you scan your Windows registry for invalid file associations and other issues related to a fragmented registry.

Answer:

NEX files have Uncommon Files, which are primarily associated with Neurological Data for Statistical Analysis.

NEX files are also associated with Nexcon System File and FileViewPro.

Additional types of files may also be using the NEX file extension. If you are aware of any other file formats that use the NEX file extension, please contact us so we can update our information accordingly.

How to open your NEX file:

The fastest and easy way Opening your NEX file means double-clicking on it. IN in this case Windows system she will choose the necessary program to open your NEX file.

In case your NEX file does not open, it is very likely that the necessary software is not installed on your PC. application program to view or edit files with NEX extensions.

If your PC opens a NEX file but wrong program, you will need to change the file association settings in your Windows registry. In other words, Windows associates NEX file extensions with the wrong program.

Many radio amateurs, trying to replicate this or that device on a microcontroller based on a magazine publication, often encounter difficulties that are inexplicable at first glance. It would seem that the serviceability of the microcontroller is beyond doubt, and the programmer is in in perfect order, and the device is assembled exactly according to the diagram, but refuses to work as it should. In such a situation, there are often complaints against the author of the development - he presented, they say, an inoperative program!

In fact, in the vast majority of cases, everything is different. The fault lies with errors made when manually entering the HEX file of the program into the computer after it was “printed” on the pages printed edition. Failures occur much less frequently when copying files from floppy disks or “downloading” them from the Internet. How to check a HEX file? The answer to this question is in the published article.

Any typo in the HEX file, even the most harmless at first glance, leads to the microcontroller (MCU) executing an incorrect command, often completely distorting the specified algorithm of its operation and can lead to completely unpredictable behavior of the manufactured device. Not even the most qualified specialist in this situation will be able to accurately indicate the location of the error based on external signs.

All that remains is to very carefully and repeatedly check the HEX file with the original. The peculiarity of our psyche is that, having checked something once, we are subconsciously convinced of our own infallibility and during repeated checks we often miss something that we did not notice the first time. Therefore, it is useful to have an assistant who, even without delving into the essence of the work, will carry out “independent control”.

Under no circumstances should program texts read by a scanner and then recognized using FineReader programs and others like her. Practice shows that character recognition errors are inevitable even with very high quality printed text.

When entering HEX files manually (from the keyboard) or their electronic versions obtained by scanning, the following most often happens:

  • instead of Latin letters A, B, C, E, Russians similar to them were introduced;
  • instead of the number 0, the letter O (Latin or Russian) was introduced;
  • the letter B and the number 8 are mixed up;
  • instead of the number 1, the letter I (Lat. "and" capital) or I (Lat. "el" lowercase) was introduced. In the fonts of some typefaces these characters are very similar;
  • the order of characters is broken;
  • the line is missing several characters or has extra characters;
  • entire lines are missing;
  • some lines are entered twice.

The most harmless of these defects is the last one. Unlike others, it does not affect the performance of the program. The same can be said in most cases about violating the order of lines. However, programmers that provide strict control over the correctness of the entered data may still reject a file with such errors.

It must be said that control of the correctness of the structure of the HEX file in the process of reading it from disk is performed by software a lot of programmers. Certain possibilities for this are inherent in the very structure of such a file, which you can read about, for example, in the author’s article “Development and debugging of devices on MK” (“Radio”, 2001, No. 5, p. 19). The trouble is that the programmer often reports only that an error has been detected without any details, leaving the user to figure it out for themselves. In this case, the defective file often turns out to be fully or partially loaded into the programmer and, if you carelessly issue the “Programming” command, the erroneous data will be transferred to the MK’s memory. After this, verification will be successfully completed (verification of the contents of the memory of the MK and the programmer) and the user will get the impression that everything is in order.

In this regard, the PonyProg program (versions 2.05 and earlier) behaves very dangerously. In addition to HEX, there are several other input file formats available, and when loading it tries to select the one it needs. Not recognizing the correct file format with errors, she still enters it as binary. In Fig. Figure 1 shows the view of the PonyProg programmer window after such an input.

Are not in memory machine codes commands, but ASCI codes of letters and numbers that make up the HEX text file. Naturally, MK will not work according to such a “program”. The view of the same window after entering an error-free file identical to the first one is shown in Fig. 2. Note that the programmer did not give any error messages or about the automatically determined file format in both cases.

The CheckHEX program can help you find and correct errors in the HEX file before entering it into the programmer. With its help, you can create a new HEX file by typing its contents on the computer keyboard. In the latter case check in progress simultaneously with data entry.

The data window of the CheckHEX program after entering a HEX file containing several errors is shown in Fig. 3. In its upper left part the current coordinates of the cursor are displayed, showing where the character will be entered when the key is pressed.

There is a window on the right, by clicking on which you can cancel or re-enable error checking at any time. Blocking control can be useful for a while manual entry data, otherwise each unfinished line is accompanied by many messages that only distract attention - The window of warnings and error messages (Fig. 4) is located below the main one. Messages beginning with the word "Information" only indicate the special status of certain lines of the HEX file. In this case there are two such lines. The first of them is optional, since even in its absence, the counting of addresses will start from zero. Similar lines (there may be several of them in different places file) allow you to address more than 64 KB (32 Kwords) of memory. It is their presence that distinguishes HEX files of the INX32 format from similar files of the INX8M format.

Line 25 marks the end of the HEX file. If any data is after it (line 26), it will not be accepted by the programmer. This can be used, for example, to place a text comment in a HEX file. In the example, line 20 was simply moved here source file, remaining empty. In principle, the presence empty lines in a HEX file is acceptable, but some programmers may still consider them errors. The CheckHEX program, just in case, warns about this.

Note the checksum error message on line 3. This may be the result of incorrect input any (except colon) character of the string, which should be checked especially carefully. The one given in brackets is "correct" check sum useful if one or more characters in a string have been changed intentionally (for example, to correct a real bug in the program). In this case, the error is the result of entering the number 8 instead of the letter B.

The nature of the error made in the fifth character of the fourth line is clear. We only note that to facilitate the visual search for errors, the text font in the main window does not contain Cyrillic characters; their place is taken by characters that have nothing in common with the correct ones. However, error messages contain Russian letters.

To the right of the data window there is a window displaying a picture of the MK memory being filled with codes from the analyzed file. A fragment of this window is shown in Fig. 5. White color corresponds to free cells, blue or red - occupied. The explanatory inscriptions in the figure (they are not in the real window) refer to the typical memory distribution for PIC controllers; for other MKs and RPOMs it can be completely different. By moving the mouse cursor inside the window, you can determine the address of any of the cells displayed there. In this case, the cursor (crosshair in the upper right part of the window) points to the byte at address OOSON - low-order in a double-byte word at address 0060H.

Of course, a user who has not designed the program being loaded and has not carefully analyzed it, as a rule, does not know which cells should be occupied and which should not. Nevertheless, it makes sense to pay attention to breaks in the continuous sequence of occupied cells and once again make sure that they did not appear as a result of errors, as in the case under consideration.

A red line indicates that the codes entered at these addresses appeared in the file more than once. In the example (see Fig. 3), the seventh and eighth lines are identical. If the duplicate line is the result of carelessness during manual data entry, it can be deleted. But more often the culprit is an error made in the address part of the line (characters from the fourth to the seventh). IN such a case not only will the codes at erroneous addresses be distorted, but the memory area to which given line treated initially. All this needs to be checked again and again.

In conclusion, we note that in the CheckHEX program window there are three control buttons: - create a new HEX file;

- open and check the existing one; - save the created or edited file. When you try to load or create another file without first saving a modified version of the old one, the program always reminds you to do this. The same thing happens before the program exits. Developers from Opera Software presented NEX - an extension format created on the basis of Chrome's CRX, but more neutral in terms of support for specific vendors. And if

in simple words , then they took CRX and based on it they created their own NEX format, which will support not only the API from Google, but also at least from Opera. And now a little more detail... When the developers decided to switch to Chromium, they carefully studied all aspects of this step. In particular, we turned our attention to the format of CRX extensions. Since this format only recognizes those APIs that Google wanted to see in its Chrome, and

Opera browser , despite its Chrome nature, has its own interface and functionality, then a problem arises: how to allow extension developers to use the Opera API? In the end, since it is very problematic to add support for the Opera API to the CRX format, it was decided to create our own NEX based on it (derived from N avigator Ex tension). Moreover, Opera decided that if we were to create

new format

extensions, then you need to make it open so that teams from other browsers can take part in its development. And in the future they plan to make it a standard, pushing it through the W3C organization. What is NEX like today? On this moment NEX extensions have the extension .nex (logical, who would argue) and are passed with the type

application/x-navigator-extension

. NEX is now CRX minus some Chrome APIs and plus an API for working with the Opera express panel. At the same time, the Opera browser, as well as their add-on store, will continue to support CRX in parallel. How will NEX support cross-browser APIs? It is stated that specific APIs of all browsers participating in development can be described in the NEX format. For example, the format supports the Chrome API via chrome.*, and the Opera API via opr.*. At the same time, developers can create universal extensions.

through type checks

If they decided to make their own interface, then they didn’t really have a choice. But two problems still remain.

Dates you need to remember if you want to receive NEX tokens.

Important: beware of scammers, the NEX token sale will take place in April, a necessary condition will be using the NEX extension or the token sale function in the NEON wallet.

NEX representatives will never ask you to send funds to another wallet.

Lottery winners will receive a number with which they can identify themselves through KYC (Know Your Customer). This number can be reproduced from the user registration information database through a certain algorithm that will be published later.

Also on this day, the KYC process for lottery winners will be launched. All lottery winners will be required to undergo a KYC process.

April 7

The KYC process for the winners of the first lottery is closed.

April 8

Second round of the lottery. Any unfilled seats for any reason will be allocated through a second round lottery.

On the same day, the KYC process will be opened for the winners of the second round. All winners will be required to complete it.

14th of April

The KYC process stage for the winners of the second lottery is closed.

Date will be announced later

Start of sales of NEX tokens.

What do you need to know about the NEX Token Sale?

To ensure a fair distribution of tokens, the sale will take place in two stages.

Round 1

The first round will take place in April and will last approximately one day depending on the closing time of the blocks. The numbers of open and closed blocks will be published promptly.

The maximum amount for one user is $1000. Minimum – 1.

Round 2

If all NEX tokens are not sold after the first round, the second round will continue for two more days or until all tokens are sold.

The maximum amount for one user is $9000. Minimum – 1 NEO.

The token sale will accept NEO and . The price of NEO and GAS will be calculated based on the 10-day moving average of the prices of the largest (by volume) exchange at the time of publication of the smart contract for the sale of tokens to the NEO main network.

How 50 million NEX tokens will be distributed

NEX browser extension

The NEX browser extension is designed and implemented keeping the user's needs in mind.

Participate in our token sale using the newly developed NEX beta wallet extension. This browser-based wallet will allow users to interact with decentralized applications (DApps) and send and receive NEO, GAS and NEP-5 tokens.

The wallet has all the necessary functions:

  • Sending tokens. Sending one or more tokens to one or more contacts at a time is an easy way to save time.
  • Transactions. Simple and clear tracking of completed and pending transactions.
  • Contacts. Easily create, edit and delete contacts that you use to send and receive.
  • Linking to decentralized applications. The extension integrates a mechanism for linking decentralized applications to purchase goods by pressing one button.

What else could cause problems?

There may be more reasons why you cannot open the NEX file (not just the lack of an appropriate application).
Firstly- the NEX file may be incorrectly linked (incompatible) with installed application for its maintenance. In this case, you need to change this connection yourself. For this purpose, click right button mouse over the NEX file you want to edit, click the option "To open with" and then select the program you installed from the list. After this action, problems with opening the NEX file should completely disappear.
Secondly- the file you want to open may simply be damaged. In this case, it would be best to find a new version of it, or download it again from the same source (perhaps for some reason in the previous session the download of the NEX file did not finish and it could not be opened correctly).
