In this tutorial we will see 8051 timers. We will use the 8051 timers to generate a precise delay of 1 sec.
8051 timers/counters
The 8051 has 2 timers/counters.
- They can be used to generate precise timing, i.e., we can measure time between events. The unit is then called timer.
- It can also be used to count external events, known as counter.
- Timer 1 is also used for generating baud rate in serial communication, which we will discuss in the next tutorial
