2020 has been an interesting year with plenty of disruption to most people lives, and political changes. Now it appears some of those changes will affect technology, and by that, I mean things like changes to datasheets and even source code. I’ve been seen a lot of talks about slave/master terminology on Twitter, blogs, and CNET is now reporting Twitter Engineer will remove racially charged technical terms from the source code and interface. Whether you are a veteran or just graduated last year, you may have to learn a new set of vocabulary to understand datasheets and code. Twitter’s senior management is allegedly backing the effort for the changes. This goes beyond racially charged terms, but if it’s the world we’re going to live in so be it. Some changes in the datasheet may not be a big issue, except for the initial confusion, but it may become problematic when changes happen in the source code as it may break […]
The first stable version of Qt for MCUs was released in August 2019 in order to bring Qt graphical toolkit to microcontrollers such as STMicro STM32F7, Renesas RH850, or NXP i.MX RT1050. Qt for MCUs would run bare metal on supported boards, and software engineers would develop graphical interface using QML and C++. Qt for MCUs 1.1 has just been released with the addition of more STM32 and i.MX RT boards, support for FreeRTOS real-time operating system, and more. Qt for MCUs 1.1 highlights: Five new supported boards: NXP i.MX RT 1064 EVK, STM32 H750B-DK, STM32 F469i-disco, STM32 L4R9i-disco, and STM32 L4R9i-eval Asset management Optional PNG compressions for assets to lower storage footprint Option to read data directly from flash memory for lower RAM consumption, or copy to RAM for better performance, at the cost of higher RAM consumption. FreeRTOS support (technology preview) to run background tasks without blocking the Qt Quick user interface Qt Charts for MCUs (technology preview) […]
Just last week I did the first part of the review of the Anycubic Photon S. One of the pain points of printing was the long workflow. Chitubox Prusa slicer Photon File Validator Photon Workshop First thing I have to decide is if the model needs to be hollowed to conserve resin. I load up the model in Chitubox and use the built-in tool to hollow the model. After the models hollowed and a drain hole is placed I export it to an STL and open with Prusa Slicer. In Prusa Slicer, I orient the model and use its auto-support feature and auto-orient feature. It is a roll of the dice if the orientation makes sense. I want all the supports to be on the back/bottom of the print. Little marks are left when removing the supports. I have found that Prusa Slicer has the best auto support feature. Then I export to STL again with the supports and open […]
You should always backup your data as it may become lost or corrupted due to hardware failure, user’s mistakes, or bad actors. However, if your data appears to be truly lost, and backup is not available, it’s possible to use data recovery software such as Wondershare Recoverit Data Recovery available for Windows and Mac OS. The program will scan your computer or specific folder/storage device to locate any kind of deleted or corrupted files and ask you which files or/and folders to retrieve. This works on drives that have been corrupted due to a crash or power failure, formatted by mistake, and so on and the program can handle both internal and external drives. Wondershare has recently released Recoverit 8.0 version with various new features and improvements: Simpler and more user-friendly interface – Recoverit 8.0 comes with a simpler and more user-friendly design as shown above. The software will show drives including lost partitions as well as external devices, and […]
This is the third part of Xtream-Codes IPTV Panel review. IPTV Panel Professional Edition is a software to build your own IPTV Server from scratch. It supports all common Streaming Protocols as an Input and it is powered by FFmpeg & nginx. If you have not done so already, you may consider reading the first two parts: Review of Xtream-Codes IPTV Panel Professional Edition – Part 1: Introduction, Initial Setup, Adding Streams… Xtream Codes IPTV Panel Review – Part 2: Movie Data Editing, Security, Resellers, Users and Pricing Management Here are the major changes since Part 2: And part of the company’s announcement of the release: Why choose IPTV Panel Pro? IPTV Panel is powered by many Open Source Tools. These are only few reasons why we believe our software is different from our competitors: Stability: Our software is powered by FFmpeg to do the Restreaming & Transcoding of your streams. FFmpeg is the leading multimedia framework, able to decode, encode, […]
Dear readers, after part 1 of Xtream Codes Panel v.2.2.0 EVO review, here is part 2. I tried hard to get all in two parts, but “to be exhaustive” there will also have to be a part 3… Movie Editing Section As we can see, it’s only possible to assign a movie into a single category, a SELECT BOUQUET Option under the Category would be more then useful. So while Movie Editor Section is useful right now, it still needs improvement. Also taking each movie by hand for editing, after, for example, a Main server crash or changing the Main, is really something, a waste of time. Some of the issues / possible improvements include: No mass edit of movies to bouquets If changing the category of a movie, I found no working method to change in a bulk.. Even if I tried to delete the “content” of a bouquet, it was denied. Left Hand Section, Mass Edit Streams allows […]
Today I’ll start the review of one of the streaming software available on the market, with version 2.2.0 EVO of IPTV Panel Professional Edition developed by Xtream-codes. The Software is mainly used for the so-called IPTV broadcasting, but also with great potential for all kind of other content delivery applications such as audio and business streaming, cloud video transcoding, and all other kind of global streams. What is IPTV? Wikipedia definition: Internet Protocol television (IPTV) is a system through which television services are delivered using the Internet protocol suite over a packet-switched network such as a LAN or the Internet, instead of being delivered through traditional terrestrial, satellite signal, and cable television formats. Unlike downloaded media, IPTV offers the ability to stream the media in smaller batches, directly from the source. As a result, a client media player can begin playing the data (such as a movie) before the entire file has been transmitted. This is known as streaming media. […]
I’m often asked what useful books software engineers should read when they start to work on embedded systems. So here’s a list of books I would recommend as starters. First, nowadays many embedded systems are written in C (although lower end systems using 8-bit MCU are still likely to be written in Assembler), so software engineers had better make themselves very familiar with C/C++ and GNU tools (gcc, libtool. automake…) with a focus on embedded systems (e.g. interrupts handling, real-time capabilities, volatile variables, processes and threads’ stack handling, , cross compilers…). Programming Embedded Systems: With C and GNU Development Tools, 2nd Edition is just the right book for that purpose. It deals with embedded Linux and eCos and provides useful examples. You may also read part of it online Once you start developing embedded systems you are likely to write device drivers at some points. Linux Device Drivers, 3rd Edition is a must have and is up-date for Linux 2.6. […]
