Timers And Counters

Create one or multiple timers and start them in any order.

Timers and counters.

Since the 8051 follows an 8 bit architecture each 16 bit is accessed as two separate registers of low byte and high byte. They can be used as timers or as event counters. Use these products for monitoring quadrature encoders event counting period measurement pulse generation pulse train generation two edge separation measurement and more. Tmod timer mode register and tcon timer control register which are used for activating and configuring timers and counters.

In arduino uno it takes 1 16000000 seconds or 62nano seconds to make a single count. A timer is an application of the counters where a certain signal with a fixed frequency hence period is counted to record the time. Timer mode control tmod. Lower 4 bits are used for control operation of timer.

Counters and timers in 8051 microcontroller contain two special function registers. Meaning arduino moves from one instruction to another instruction for every 62 nano second. In modern applications counters are based on electronic devices and the counters are sequential logic circuit designed to record the number of electric pulses fed into the counter. The 16 bit register of timer 0 is accessed as low and high byte.

Set a silent timer clock or choose a sound. Timer online with alarm. Tmod is an 8 bit register used for selecting timer or counter and mode of timers. Both timer 0 and timer 1 are 16 bit wide.
