INTERNAL STRUCTURE OF MICROCONTROLLER(BLOCK DIAGRAM)
GOOGLY: HOW DOES MICROCONTROLLER WORKS?
WELL I
CANNOT GO IN DETAIL ABOUT WORKING
because it is a vast topic in itself. I can just give you a overview-
Microcontroller
consist of a CPU which is interfaced to
RAM and FLASH MEMORY. You just feed your program in flash memory of
microcontroller. now when you turn
microcontroller ON , CPU accesses the instruction from RAM which access your
code from FLASH. Its sets the configuration of pins and starts performing
HOW TO DO CODING/PROGRAMMING FOR MICROCONTROLLER?
YOU CAN WRITE PROGRAMS IN JAVA C++ AND C. THEN WE COMPILE THE CODE TO GENERATE ITS MACHINE LANGUAGE ie 0 and 1, NOW BURN IT IN MICROCONTROLLER USING A PROGRAMMER AND A SOFTWARE.
BETTER OPTION WOULD BE MAKING PROGRAM IN C AND THEN COMPILE IT IN MACHINE FILE(.hex) . AFTER THIS WE FEED PROGRAM IN FLASH MEMORY OF MICROCONTROLLER USING SUITABLE PROGRAMMER.
THIS PICTURE ABOVE IS A PROGRAMMER USE TO BURN OUR PROGRAM IN MICROCONTROLLER.
we will discuss about programs and softwares and hardwares to be used in upcoming post.
