Hi there
I have a LM358 amplifie-ing a maic signal to my pic16F913 AD input, this signal is used to drive 8 LED's in a VU meter fasion This part works fine.
Now i have a input that when made gets the signal and set a alarm setpoint one LED lower than the current signal === First problem with the signal variang fast it does not whant to select properly
Now what needs to happen is that as soon as the signal passes the setpoint again it needs to set a output basicly a high noise alarm, but my rele shutter if i add a timer it influence my VU meter
any one with some idea, here is my code for info
Code:INCLUDE "MODEDEFS.BAS"
