Silicon chips are like pop music acts. Most get outdated quickly, but those that don’t tend to stay forever.

PULSE click

Last year’s hottest hits are already forgotten, whereas Beatles or Rolling Stones songs are still being played, morphing into different formats to fit the times — from vinyls to cassetes, from cds to mp3s.

You can say the same about ICs – the longer a particular chip has been on the market, the longer its likely to survive into the future, impervious to Moore’s law (see Lindy Effect).

There are many such examples in the embedded industry, but perhaps none better than the NE555 timer/pulse generator – it’s a classic that has been introduced in 1971, and billion units are still being sold yearly.

Now, as it adapts itself to the needs of contemporary developers, it got itself on a click board.

PULSE click carries a NE555 timer produced by Texas Instuments. As the name implies, here it’s used as a Pulse generator, coupled by a circular switch with two potentiometers to fine tune the frequency, in a range between 0.05 Hz and 1000 kHz.

The output can be configured to be sent either as a digital signal through the OUT pin or an interrupt.

See the details on the product page, and start tinkering with the Libstock library.
