            Send a REST message for each Cypress test result
            Asked 2022-Mar-17 at 15:41

            Is there a way to call a REST api based for each cypress test result?

            We have a zephyr test definition system, and we must use it's API (https://support.smartbear.com/zephyr-scale-server/api-docs/v1/ ) to change the status of each testcase our testers defined, as part of the automation processes we have in our company.

            In my research the only solution we found was to use a Reporter (https://docs.cypress.io/guides/tooling/reporters) and then parse the results with a small script which generates the said REST calls for each test result.

            I was wondering: is there any more elegant solution to call the zephyr app directly, via Cypress maybe?

            The missing part here was the devicetree bindings, https://docs.zephyrproject.org/latest/guides/dts/bindings.html#, that a dt entry has to match in order to be correctly processed.

            The tip to figure this out came from the zephyrproject issue tracker: https://github.com/zephyrproject-rtos/zephyr/issues/42404

            Building multiple binaries in CMake from Zephyr RTOS project, each with different device address
            Asked 2022-Jan-25 at 20:25

            I have a project that consists of nodes in a mesh, that will communicate between each other wirelessly and will identify each other with a use of addresses.

            Nodes will be equivalent in their responsibilities so the source code for each them will be identical, except for address which I would like to be specific and unique for each.

            This project will be a kind of demo, or technology demonstration so for simplicity I do not want to introduce some address negotiations or anything complex like that.

            I ran multiple imputation to impute missing data for 2 variables of a data frame, then I got a new data frame (with 2 columns for 2 imputed variables).

            ANSWER

            Answered 2021-Nov-22 at 06:04

            "%object"" is a GAS assembler directive specifying a symbol "type":

            From the Binutils documentation:

            https://sourceware.org/binutils/docs/as/Type.html

            For ELF targets, the .type directive is used like this:

            .type name , type description This sets the type of symbol name to be either a function symbol or an object symbol.

            More generally:

            The .type directive allows you to tell the assembler what type a symbol is. Most of the time we just use %function and %object.

            Simulate Multithreading with semaphores in a single thread
            Asked 2021-Nov-10 at 01:37

            I want to simulate the firmware (C++) of an embedded device on a Windows machine (C++). The firmware runs on a microcontroller (nRF5340) and runs Zephyr as an operating systes. Within the real firmware there are multiple tasks.

            The challenge is now: I want to be able to create multiple instances of one virtual device, but each device should only run in one single thread.

            Semaphores are used for multi-threading (in the firmware), which are blocked or released. Is there a way I can use semaphores in a single thread and implement a kind of context switch?

            So that, for example, a function is called that runs through to a semaphore. When the semaphore is reached, a new function can be called which releases the previous semaphore so that the original function can continue (but all in one single thread).

            ...

            ANSWER

            Answered 2021-Nov-10 at 01:37

            This can be done with coroutines. A coroutine is like a function, but at some point in the body the programmer calls yield. This saves the state of the coroutine. It can be resumed later at the point where it yielded.

            Coroutines were added to C++20. However, they didn't yet add specification for a task-management library. It would be a significant amount of work to implement yourself. You can find 3rd party ones. Boost also has 3 coroutine libraries that predate C++20 (1 old, 1 current, and 1 specifically for Asio). Using a 3rd party task-management library is probably the superior approach, but you will have to use C++20 and learn a new library that might go obsolete pretty quickly.

            Alternatively you could make a work-around if you allowed each virtual device to spawn an actual thread for each of its simulated threads, then programmed some kind of synchronization so only 1 thread per virtual device runs at any given time. You're essentially taking advantage of the fact that a real thread has context switching built in. I would use this approach, as it avoids a lot of development on things tangential to your project, and I already know how to use threading tools.

            Lastly, you could create a "stack" for each simulated thread and do the context switch yourself. You'd lose portability. Basically you're writing your own coroutine library, but it's tailored to your use case so it would be easier to use. However, the dev time would probably balance out with just learning how to use an existing library.

            Going back to the middle approach (a real thread for each simulated thread)... your yielding function could look something like:

            Each simulated thread has its own semaphore (so you can specify which to call):

            No vulnerabilities reported

            Install Zephyr

            In Xcode, open your app's project/workspace file:. Before performing each sync, Zephyr automatically checks to see if the data in UserDefaults or NSUbiquitousKeyValueStore is newer. To make sure there's no overwriting going on in a fresh installation of your app on a new device that's connected to the same iCloud account, make sure that your UserDefaults are registered BEFORE calling any of the Zephyr methods. One way to easily achieve this is by using the UserDefaults Register API.
