Hi, I am correcting a C code which was written for a flame machine. My desire is to give a burst cool time when the machine working continuously. In deep, user could have the facility to enter the flame time and cool time before a continuous operation. So, i exactly want to off the current when user time met the flame time and then cool period starts here and so on continuously. I thought of using Sleep function with an argument of user entered cool time. Is this handle other interrupts in this period? Or any other suggestions would be appreciated.
