Hi So, considering going the Cortex Mx route for project with new microcontrollers at our firm. Has anyone a feeling/information about the development speed of the ARM Cortex Mx series vs the rest of the industry? Meaning, that potentially the same core strategy for the ARM, licensing to toher manufactors mean that they may have faster development speed that others (Microchip, Renesas, wh...

I hacked together my "IP cameras" using some web cams for which I was able to track down some FOSS i/f implementation documentation. This was OK for a proof of concept. But, I now have to settle on "production" hardware. There seem to be a variety of i/f's for cameras: - RS170 (requires hardware to digitize the signal; inflexible) - parallel (video is digized, just needs to be captured a...

Maybe this question should be posted in a linux development group, however the use of a serial port is more typical in an embedded environment, so I try to post here. I have an embedded Linux box (based on a Raspberry) with a serial port converted to a USB port through a UART-USB transceiver from Microchip. This USB port is seen as a COM port under Windows OS. I need to do simple ope...


Resource constraints as a bound to complexity

Most of my designs have been ultimately constrained by the resources available *in* the design (which, in turn, is usually dictated by price, power and/or size constraints). I've been discussing this with colleagues who have invariably had similar experiences. None of us could "upgrade" a product after release. You might change the feature set or fix bugs but the complexity of the produc...

Hi, Some time ago, I boght a cheap devboard from a well known Chinese webshop with a STM32F103RCT6 chip on it. According to the datasheets, that chip has 48 KB of RAM and 256 KB of flashrom. However, when using the linux arm-gdb and the st-util and st-info, they say that the chip actually has 64 KB of RAM (so more then exptected). Using gdb (writing to memory and reading bac...
