SUMMARY

The discussion centers on selecting an appropriate integrated circuit (IC) for counting encoder outputs, specifically addressing the use of the 74LS47. Participants clarify that the 74LS47 is not suitable for this purpose, as it is a BCD to 7-segment decoder rather than a counter. Instead, they suggest using counter ICs that support up/down counting, particularly for quadrature encoders, which output two signals for direction detection. Understanding the logic design for processing these signals is essential for implementing an effective counting solution.

PREREQUISITES
  • Understanding of quadrature encoder outputs
  • Familiarity with up/down counter ICs
  • Basic knowledge of digital logic design
  • Experience with signal processing for counting applications
NEXT STEPS
  • Research suitable up/down counter ICs, such as the 74HC393 or 74HC4040
  • Learn about designing logic circuits for processing quadrature encoder signals
  • Explore the implementation of counting mechanisms with quadrature encoders
  • Investigate the use of microcontrollers for handling encoder inputs and counting
USEFUL FOR

Electronics engineers, hobbyists designing motion control systems, and anyone working with encoder-based counting applications will benefit from this discussion.

i am want to make circuit that use an encoder counters..
but i don't know which ic can counter for encoder??
i am using 74LS47 for encoder counters?but, it didn't work??
is 74LS47 can use for counter encoders??
which IC can used for encoder counters??
thanks anyway

What exactly is an 'encoder counter?'

- Warren
 
My guess would be that he has a quadrature encoder output, and wants to count up for rotation in one direction, and count down for rotation in the other direction. Is that correct, novrisa?

How many bits of counting do you need? Do you know how to design the logic to take the quadrature encoder outputs (two signals, correct?), and use those to make an up/down signal and a counter clock signal? Then, do you know of counter ICs that have an up/down count control input?
