HI all,,,, I need a small help from you all.... actually i am new to electronics and programming part. i am making a small project in which i need to enter the idle mode to save the battery consumption done by my 89S52. i have written a code to enter the idle mode...
PCON |=0x01;
my microcontoller has entered the idle mode but not aware of how to exit it... have gone through the data sheet twice but not able to understnad anything... yes.... understood a bit... so in that case i wrote a code to exit idle mode...
EX1=1; EX0=1; ES=1; IE1=1; IE0=1; EA=1;
but ths thing does not work..... i want to exit the idle mode on a keypress... can nybody help me with the code....
how can i do that..... how it ia possible to run a loop in idle mode... idle mode stops the CPU. i have tried using the code above.... but it doesn't work.... do u have any code for that....
DUH! run a loop in idle mode?
it is very easy. keep check keyboard in loop. if you see a key do reset processor to wake up.
