I have a board with Cortex-M3 NXP LPC1875 MCU with 512kB internal Flash, one 8MB external SDRAM and 2MB external SPI Flash. The external Flash is connected to a normal SPI, not SPIFI (in other words, it isn't mapped to the internal address space). Insted the SDRAM is mapped to the internal address space, starting from address 0xA000 0000. The application will use a 480x272 RGB LCD conne...

It's a long time I work with embedded platforms, however I never used a well-defined and "standard" data serialization format. I often had the need to exchange data between platforms (Wifi, Ethernet, RS485...) and I always find a custom solution. I perfectly understood the problem with this approach. Keeping the two (or more) side synchronized is very difficult and error-prone. When the...

Subject: Update about Ada-Europe Conferences 2019 and 2020 The 24th edition of Ada-Europe's International Conference on Reliable Software Technologies took place on 11-14 June in Warsaw, Poland, with considerable success. The conference, graciously hosted by the Institute of Aviation, had nearly 100 participants, enjoyed a rich technical and social program, and saw much active interactio...

I normally don't use dynamic allocation in embedded projects, however there are situations where this isn't possible. I'm working on a project with LPC1768 Cortex-M3 MCU that features 32kB+32kB RAM. I'm using lwip+mbedTLS to make a TLS connection to AWS IoT Core through Ethernet. After a precise allocation of data blocks (incoming Ethernet packets, outgoing packets and so on), it see...

Just when you thought it was safe to fly again... It make me think that every time you add code to close a loop-hole, you open new, smaller loopholes around the boundaries. Clifford Heath.

It took a very long time to realise that this wasn't a bad parody. If you were the engineer who implemented this, kill yourself. It's not a sin; you have no soul anyway.

We use the Hitachi H8S2676 chip in one of our products and a while ago Renesas told us the chip was going out of production. Someone here forgot to do a lifetime buy from them in time but we recently did a lifetime buy of several thousand from a third party company. In the first production run of over 100 boards, every single one failed the manufacturing test. It seems at least o
