This hit the news yesterday: SQLite contained a remote code execution bug. According to the ZDNet article the bug has been fixed as of v3.26.0 released December 1st. If your application uses SQLite, you may want to look into updating it. https://blade.tencent.com/magellan/index_en.html https://www.zdnet.com/article/sqlite-bug-impacts-thousands-of-apps-including-all-chromium-based- browse

Nowadays the poor embedded developer faces new challenges that go outside the limited world of C/C++ program on a resource constrained hardware. Now the hardware isn't so resource constrained (Raspberry and many other embedded Linux boards or SOM are just examples) on one side. And the device isn't isolated anymore, it is usually connected (directly or indirectly to Internet). The Th...

For a test setup, I have created a small UI using the serial port connected to a VT100 capable terminal (Tera Term). I use the VT100 commands to create a "nice" (for certain values of nice) looking output. This works OK. But now I periodically (every few seconds) have an amount of data that needs to be stored on the PC. A CVS like output with a 100 lines or so. I can just spit this out aft...

What do you really use for embedded projects? Do you use "standard" makefile or do you rely on IDE functionalities? Nowadays every MCU manufacturers give IDE, mostly for free, usually based on Eclipse (Atmel Studio and Microchip are probably the most important exception). Anyway most of them use arm gcc as the compiler. I usually try to compile the same project for the embedded target...

I'd like to replace an electrical cable with a fiber cable, mainly for electromagnetic noise immunity and long distance (I need to reach 500m). The bitrate will be very low: 9600bps is ok. I need to keep the cost low as possible. I never used fiber cables before. In similar applications I used RS485 transceivers connected to the UART peripheral of an MCU. I think I need a fiber optic c...

I am having an old board made and am being asked for ODB++ format CAD data files. It seems this is to facilitate the creation of the various machine control files. I'm told it can also support locating traces to assist in debugging. My CAD package doesn't support this. Would it be a hard thing for the developers to add? https://www.odb-sa.com/wp-content/uploads/odb_spec_user-
