7400 competition entry: Lighting effects generator

Posted on Tuesday, November 6th, 2012 in 7400 contest, contest by DP

 

Dmitriy entered his lighting effects generator into the Open 7400 Competition.

The basis of the device is a multi-bit digital sequence generator that is implemented on a serial shift register [1]. The repetition period of the sequence is determined by the number of bit of a register and much higher than the repetition period clock. For a sequence containing all possible states of the register, excepting the zero state (so-called M-sequence) the value of the period is Tn = (2n-1) / f, where n – number of bit of a register, f – clock frequency in Hz.Via the contact form.
