I should have included this with my previous post. It seems that function I2C_WriteToSlaveis also not part of v10.72D. Couldn't a macro have been defined to provide backward compatibility? Steve

Hi Folks- FreeRTOS has a build config file (FreeRTOSConfig.h) that users can apply at build time to customize the RTOS. The FreeRTOS web site has a page to describe the options (https://www.freertos.org/a00110.html). What it doesn't have is any hints about how much RAM it might save me. Does anybody have any first hand advice about how much RAM each option might contribute to the R...

Has anyone had any experience using the erc802-1 series of serial (i2c) lcd modules ? I have not yet succeeded with getting mine to display anything and any suggestions would be most welcome. This is what I am doing - I am using the power-on reset with the reset input wired to +5v. In software I wait for about 50ms after switch on, then execute code which produces the clock (yellow) and dat...

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...


Re: Consistency of DCO parameters across multiple samples of a given par

DCO is not accurate indeed. That's why TI programs DCO values during manufacturing. Some kind of calibration is inevitable.
