Hi group! As a n00b in the IoT domain I have had trouble finding a suitable open source implementation in C for the LWM2M protocol with DTLS support. What I have found so far are following implementations: - Contiki lwm2m: https://github.com/sics-iot/lwm2m-contiki - Wakaama LWM2M: https://github.com/eclipse/wakaama - Awa LWM2M: https://github.com/FlowM2M/AwaLWM2M - Anjay: https://gi

Hi Recently more and more companies want to add security (authentication and/or encryption) to their devices firmware install/update process. Typically this is done by storing a secret encryption key in bootloader or elsewhere in internal MCU flash. This should work if bootloader is installed in secure facility by trusted people. But then manufacturing is outsourced/offshored and t


Digital mic sharing on two MCUs

Hi there- I have a design inquiry that involves interfacing a pair of digital MEMs PDM microphones to two different MCU's (one for wake word processing and another for speech processing after waking). Such a design would reasonably require two clock sources to the mic. Does anybody know what design strategies exist so that PDM mics can be shared among different downstream audio proc...

I usually prints some messages on a free UART used as a debug port. They are very useful during debugging to understand the flow of execution. Most of the time, I don't compile the debug log facility in release build. I sometimes need to disable messages from some modules and enable messages from other modules under debugging. Moreover I sometimes need to enable/disable less important m...

Hi folks- Does anybody know what memory devices are embedded in the Datakey memory tokens? For example, this part: http://datakey.com/downloads/SST_Series_DS_REVD.pdf which is from datakey.com. I'm pretty sure these devices are just embedded serial EEPROMs but Datakey doesn't reveal the part inside. Thanks - John

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...
