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

Select option -> Generate Code -> Build -> Build fails. Select different option -> Generate Code -> Build -> Build fails. Try yet another option -> Generate Code -> Build -> Build fails. Harmony is a giant framework where you select from hundreds of options (drivers, TCP stack, etc), then generate your application's frame. It favors a monster-loop state machine, at a point where the applica

I need to save some data on a non-volatile memory. They are some parameters that the user could change infrequently, for example 10 times per day at a maximum. In the range 100-2kB. As usually occurs, the parameters that changes more frequently (10 times per day) are fewer than parameters that changes very rarely (10-100 times in the device lifetime). How to save those data? After d...

I've just been trying to use avra, but it outputs coff or something, so obdump has trouble disassembling it. I am also not sure how to link the result(ihex have no symbol info). So now I believe the thing is next to unusable. Someone correct me if I am wrong, plz. Are there any other, usable alternatives to Gas that have usable macro constructs (+labels)?

Use of soft float?

While those who make heavy use of floating-point computations in embedded sytems probably go for systems with hardware support for floating-point calculations, there are plenty of systems without such support out there. And the existence of soft float implementations indicates that there is a real need for doing floating-point computations on systems without hardware floating-point support. ...

Asymmetric multiprocessing (AMP) systems fulfill the need for high performances and real-time by combining the responsiveness of a MCU (Cortex-M) with the processing power of an application processor which runs a full OS. This webinar presents a technical overview on asymmetric multiprocessing and its implementation on an NXP i.MX 7 Colibri System on Module running Android on the MPU (Cortex-A,...

What are folks using for reliable file system on for example SST26VF064B 64Mbit SQI flash? Naive FAT will quickly wear out device for some uses; needs a wear-leveling file system. Needs to be power-off safe as well; no corrupted file system from arbitrarily-timed power cut. Anybody? Thanks, Best Regards, Dave PS: A customer of ours used TINY by HCC some years back. It is unfortunately ...

It has been a while since I looked at anything Cypress. I have a couple of PSOC something sticks that were fun to play with a bit, but I never used the CPU for a project. Now they have come out with a PSOC 6 with asymmetric dual processors, and M4 and a M0+ with an optional BLE radio and stack. Looks like they are using the M0+ to control the BLE and the M4 is for user code. I t
