embedded multiplatform C - emC is a collection of C sources and a concept to write applications in C for embedded systems:

Goals

• Test of algorithm on PC platforms (Visual Studio or Eclipse) near to target conditions
• Reusing of unchanged sources for several applications and platforms
• Object oriented architecture in C
• Using C and C++ compiler
• ==> emC_approach

• Example Course using MS Visual Studio

• in new tab/window: 12 slides as an overview (in german)

• Entwicklung und Historie (in german)

• ==>Getting test and sources from Github(since 2020-02)

• Test strategies for emC sources (since 2020-02)

• compl_adaption.h - supports portable programming

• applstdef_emC.h - controls the details

• quasi language extension for portable programming

• ObjectJc.en.html

• ClassJc.en.html

• ThCxtExc_emC.htmlThreadContext, Stacktrace and Exception handling

• ExceptionHandling_de.htmlException handling mit Umfrage (german)

• Some article using C++ for embedded control (starting in Dec-2020, english)

• Virtual operations in C++, safety, alternative

• Virtual operations Umfrage und Schlussfolgerungen (german)

• EventQueue_de_2020-02-20.pdf: EventQueue in Embedded Control (german)

• Application programming in interrupt, vs. using RTOS

• Atomic access, compare and swap, using in interrupt and backloop, especially for a Ringbuffer, common approach for container useable in interrupt, backloop and RTOS thread

• Inspector Target Proxy access

• Controlling Function Blocks

• Some slights, writing style, defines, C or C++ (pdf)

Link to my own article in german:

• Artikel in ESE: "C++ in der Embedded-Entwicklung: Embedded-Code am PC testen" (german)

• Artikel in ESE: "C++ in der Embedded-Entwicklung: Umgang mit Heap-Daten" (german)

• Artikel in ESE: "C++ in der Embedded-Entwicklung: Keine Angst vor Templates" (german)

• Artikel in ESE: "C++ in der Embedded-Entwicklung: Exceptions und Assertions" (german)

• Artikel in ESE: "C++ in der Embedded-Entwicklung: Exceptions in schneller Echtzeitverarbeitung" (german)

Link to other article to this topic (german). Note: Some representations, in some cases, are not my point of view.

• Artikel in ESE: "C++ für Echtzeit-Anwendungen" Grundsätzlich richtig, es wird aber zu stark die "Strukturierte Programmierung" betont. Wo liegen die eigentlichen Unterschiede .... in Bezug auf Rechenzeit. Aus meiner Sicht: Stichwort 'Referenzierte Daten' fehlt.
