Timer 0: Delay Generation
The ATmega8 microcontroller, a vital component in the realm of embedded systems, stands out for its versatility and efficiency.
Timer 0, an 8-bit timer/counter in the ATmega8, is instrumental in a variety of applications, ranging from simple delay routines to complex pulse width modulation (PWM) tasks.
Its ability to measure time intervals, generate waveforms, and trigger events makes it an indispensable tool in the toolkit of any embedded systems programmer.
Understanding Timer 0 Registers
Before coding, it's important to understand two key registers associated with Timer 0 -
TCCR0 (Timer/Counter Control Register)
This register is used to configure the timer mode and set the prescaler.
TCNT0 (Timer/Counter Register)
It holds the current timer count and is automatically incremented as the timer progresses.
