If we re playing with a microcontroller from ATMEL MCS51 family, often in the design of the program requires routin-routin timer (delay) a lot, because it needs time delay of each component can be different, and from there we are again counting memory used, with This software is sufficient to fill tundaan we want the routin-routin will appear on the screen.-If we were playing with a microcontroller from ATMEL MCS51 family, often in the design of the program requires routin-routin timer (delay) a lot, because it needs time delay of each component can be different, and from there we are again counting memory used, with This software is sufficient to fill tundaan we want the routin-routin will appear on the screen.
