Analogue ports, timers, UARTs, and clock generators ... and he’s produced a handy square wave generator for which he’s placed code on GitHub and produced a write-up (Italian language ...
Fed into a 4060 binary ripple counter, that clock is divided down 14 times to deliver a 2Hz square wave. This then goes through a 4027 flip flop to get the desired 1Hz signal. From there ...
A waveform that rises quickly to a particular amplitude, remains constant for a time period and drops fast at the end. In digital systems, square waves are the norm, because they represent a ...
