waveform generator using attiny85

waveform generator using attiny85 As discussed in the previous article ATtiny85 has a special 64MHz clock that can be configured along with Timer/Counter1 to fast digital to analogue conversion.  For doing so, initially the clock source has to be specified for Timer/Counter1. So the 6MHz clock is turned on.To make Timer/Counter1 act like a digital-to-analogue …

Counters in attiny85

Counters in attiny85 Like Timers, counters are also peripherals in microcontrollers. As the name suggests,attiny85 counters are used to count external or internal clock pulses. Such pulses/events that are counted are stored in certain registers which can then be further processed and retrieved. As the timer module in ATtiny85 is 8-bit, the counter can count …
