VHDL PULSE COUNTER - PLS HELP
Hi all,
I would appreciate any help anyone can provide. I am sending a random number to a CPLD pin from another device. I need to write VHDL code to count how many pulses are coming through in a space of 1 second. I also need to send this number of pulses out of one of the CPLD pins somehow. I would GREATLY appreciate any help,code, tutorial referal....from anyone...thnx in advance. crazy_kuts |

When the timer expires, its output is LO. Feed this output into the enable pin of your counter that counts pulses. This ensures that your pulse counter only runs during that 1-second period. -Dave Pollum Dave Pollum |
