An approach which may be regarded as a company advanced programming interface (CAPI) applicable, for instance, to boiler displays and remote man-machine interfaces. CAPI may use a product software structure combined with a personal computer (PC) or web based program capable of creating an embedded microcontroller program without a need for programming capabilities or a program recompile. Implementation may be done at both the product microcontroller level and the PC or web based program to be used by an end customer to “customize” its product. The present approach may partially move development and final tuning processes to an original equipment manufacturers (OEM). Modifications of the product may be done without a need for specific and expensive software development tools for embedded devices such as a compiler and a debugger, and hardware tools for simulation and analysis, and other like items. The present approach may also provide immediate response to simple OEM requirements.
