Hi,
I'm assuming that you want to measure speed and direction on the 30
servos. This would require 60 inputs (A & B), If you do an new FPGA
load you could read 8 servos with the base 7300. 16 if you don't use
the VGA output.
I would therefore look at using a FPGA PC/104 card or interface a
number of encoder ICs to the PC/104 bus. A further option would be to
sample the quadrature channels at high speed with a chip select for
each encoder. if you could read the inputs fast enough you could get
simultaneous sampling over a larger number of channels, but this
would need a FPGA expert to work out.
Regards,
PJE
