Quadrature encoders have many uses in position-sensing applications. This implementation uses a Xilinx complex programmable logic device (CPLD) to count the pulses from the encoder and determine the ...

This article is part of the Ideas for Design Series: Vol. 3, No. 8. In many applications, accurately sensing the position of an electrically controlled mechanical device such as a motor is critical.

The LS7082N1, LS7083N, LS7084N, LS7183N and LS7184N quadrature clock converters interface incremental encoders to counting devices by converting outputs into up/down clocks or clock and direction ...

Providing a 32-bit-wide datapath, the four 60-MHz TMS320F280xx DSP-based controllers include an on-chip, 12-bit ADC and QEP (quadrature-encoder-pulse) interfaces. A timer captures and compares the ...

Special hardware can overcome software latency that may otherwise negate precise motion control. Precision motion control is virtually never an end in itself. Rather, it ties position to other events ...
