Question
What is the resolution of Timer/Counter0 when the CPU frequency is set to 16MHz and the following code is used for configuration of prescaler:TCCR0B |= (1<<CS02);Give your answer in microseconds (us).
Solution
Para resolver esta pregunta, sigamos los siguientes pasos:
-
Identificar la frecuencia del CPU: La frecuencia del CPU es de 16 MHz (16,000,000 Hz).
-
Determinar el valor del prescaler: El código
TCCR0B |= (1<<CS02);configura el prescaler del Timer/Counter0. Según la hoja de datos del microcontrolador (por ejemplo, ATmega328P), el bitCS02corresponde a un prescaler de 256. -
Calcular la frecuencia del Timer/Counter0: La frecuencia del Timer/Counter0 se obtiene dividiendo la frecuencia del CPU por el valor del prescaler.
-
Calcular el período del Timer/Counter0: El período es el inverso de la frecuencia.
Por lo tanto, la resolución de Timer/Counter0 con la configuración dada es de 16 microsegundos (us).
