I have a CPU board that interfaces to a standard 16x2 chars display, based on HD44780 controller. I'd like to replace this display with a full-color big TFT display, maybe 10", but I can't change the firmware of the CPU (because I don't have the source code and I can't rewrite it, because of cost and time). The simple idea is to create an interface between the current CPU board and t...

arm gcc and Cortex-Mx MCUs embedded systems. Is there a compilation-time (static) tool for stack analysis that really works? The best I could find is -fstack-usage and avstack.pl Perl script, but I guess there's another and better way.


Shutdown behavior and flash storage devices

Hi All - I'm wondering what other folks do about this issue... Consumer flash storage devices (USB memory stick, SD card, etc) have a nice internal wear-leveling controller. When one does a write operation, lots of sectors may be internally rejiggered to provide uniform wear (so things that are never rewritten from the application point of view are actually moved around and rewritten). T...

Sometimes things move faster than expected. As someone with an embedded background this caught me by surprise: Tera-Byte microSD cards are readily available and getting cheaper. Heck, you can carry ten of them in a credit card pouch. Likely to move to the same price range as hard disks ($20/TB). That means that a 2+ square inch PCB can hold a 64-bit processor and enough storage for memo...

Jonathon - I'm in the testing phase now but, thankfully, strictly 32 bit code. One trick I've found that's been helpful is "fasmarm", which is an offshoot of a 386 et.al. assembler. The name is, if memory serves, flat assembler or fasm. I've got it on a Microsoft xp msdos directory. The fasmarm handles the 64 bit codes which might make it useful for you. Hul Jonathan Harston

I used a simple driver for serial port in Linux with success in many projects, but recently I found an issue with it. The scenario is an embedded Linux (running on iMX6) that runs a QT application (that creates a GUI on a touch display) and a C application that communicates over a serial port. When QT application starts some complex graphics (I see its CPU load reaching 70-80%), the ...
