![]() This program enables the PC to receive commands in the form of abbreviations and convert them unerringly into so called “executable file”. This problem was also easily solved by means of the program for a PC called assembler and a simple device called programmer. The main problem of remembering codes recognized as instructions by electronics was solved therefore, but another one, equally complicated to both us and “them”(microcontrollers) arose. In order to bridge this gap between machine and humans, the first high-level programming language called Assembly language was created. The bad one is that, even primitive, this language of zeros and ones can only be understood by microcontrollers and some of the experts working on its development. Fortunately, they still didn't progress so far in their evolution, so that all microcontroller families “understand” only one language - machine language. Namely, unlike other circuits which only need to be connected to other components and powered in order to be of any use, microcontrollers require to be programmed as well. It was time that hardware-oriented to the core made compromise if they wanted to stay “in the game”. ![]()
