JSON (JavaScript Object Notation) is a lightweight data interchange format. JSON is widely used in internet-related development, and it is also quite common in embedded systems. Recently, I used it in a project, and I would like to share my experience. An example of a simple JSON formatted data is as follows: { "name": "xxx", … Read more
In software development, every change in requirements generally requires rewriting code, and after code changes, functionality testing is needed. Of course, before functionality testing, unit testing of the code is necessary to avoid unverified scenarios after code modifications, which can lead to various issues. Using a testing framework to quickly complete unit testing of the … Read more
The ELF 1 and ELF 1S development boards are compatible with the OV5640 camera, which integrates a CMOS image sensor. As a 5-megapixel camera, it supports image output with a maximum resolution of 2592×1944 (QSXGA) and a frame rate of up to 15fps. It also supports high-speed VGA (640×480) image capture at 90fps, demonstrating excellent … Read more
Click the blue text above to follow us Transitioning embedded SoC development from single-process multi-threaded architecture to multi-process architecture is a task that requires careful planning and implementation, especially in resource-constrained embedded systems. This architectural change is typically aimed at improving system stability, isolation, security, and concurrent processing capabilities. In a single-process multi-threaded architecture, multiple … Read more
