WebIn your application, a reasonable design would be to have an interrupt every ms, which increments and checks a counter value. I'm sure you can work out some suitable logic to set and test the counter to get 200 ms between turn on and turn off events. In the worst case, an ISR can run until the next interrupt of the same type occurs again. WebInterrupt Vectors in Atmega328P Interrupt vector is a deﬁnite address in the program memory where a JMP instruction should be written to jump to the ISR corresponding to the interrupt. Each interrupt vector occupies two program memory words in order to provide space for JMP instruction. In Atmega328P, the RESET Vector is affected by BOOTRST ...

WebThe provided code is only intended as an illustration; timers, interrupts, or other hardware peripherals may be needed for the actual implementation. The subroutine offers a straightforward and modular method to produce time delays in multiples of 2 seconds, which can be helpful in a variety of applications, including timing and control systems. WebATmega328P External Interrupt Enable The ATmega 328P supports two external interrupts which are individually enabled by setting bits INT1 and INT0 in the External Interrupt Mask Register (Section 12.2. 2 EIMSK). When an edge or logic change on the INT0 pin triggers an interrupt request, INTF0 becomes set (one).
