How Microcontrollers Work

Hi ! This post present How Microcontroller’s work ?  ! ActiveHigh invite you to watch this video :

A microcontroller is an integrated circuit the function in the same way as many as computer .

you can find microcontroller in many household appliances such as TVs remote , coffee makers , microwaves of them and more .

most modern microcontrollers will contain at least three key components ,  a processor core which access the brain of the microcontroller , program memory  which contains instructions that help the brain what to do , and input / output processing external data .

let’s take a look at how the inside of the microcontroller works .

each one represents an operation ,the core or chicks in this case executed operation the next one is being fetch .

the simultaneous fetching and execution is called pipeline and it is faster and more efficient than the mother were gone more and chicks done eating

and fetch another worm .

some worms are larger another’s ‎and chicks need to break to the pieces in order to.

this is equally true of the words size of processor the larger the chick the larger the worm and Kenny one go end , the higher the word size of  processor the more data it keep process at a time .

let’s run true the full cycle first in operation is fetch program memory is operation who access of their data temporary storage input/output  as ones and zeros the operation is then executed by the core as the next operation is being fetch

the new instruction are fetch then executed and this repeat tell the program finishes running or until the bird is out of work for the day .

when the microcontroller is reset for the days are new the birds the entire cycle starts again .

now that we have an practical understanding of how microcontroller works let’s take a look at what they can do because of their small size , low cost and low power . microcontrollers are now used in most modern electronic devices .

for example let’s take look at the key fob for your car . it’s not generally Sunday you pay much to do . you press a button and your car unlocks but have you ever wondered how this works .

a kay fob like a microcontroller contains at least three key components ,

buttons the microcontroller self and transmitter .

when a button is pressed in generates a signal call the interrupt to the microcontroller .

this causes the microcontroller to run a very specific tasks called interrupt service routine (ISR) .

inside the key fobs the birds are asleep until they are woken up by the button interrupt .

the ISR for the given button is than fetch then executed the birds that go back to sleep .

the ISR generates a series of 1 , 0 that sent to transmitter.

the transmitted goal is recognized by a microcontroller inside the car assured a lock and unlock the car stores .

with truly is possible codes you can be assured a only your key combination the work with the your car
