This is a job for the smallest/cheapest micro controller. An Arduino clone could do this The software could read an analog pin then program a count/timer to make pulses. Then while the chip's hardware pulse generator runs, the software periodically reads an analog pin and re-programs the timer to go faster or slower. Details are things like the range of the analog signal the requires D/A conversion resolution and how many times per second you need to read the analog signal. -- Chris Albertson Redondo Beach, California ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
