Right!!! It wasn't the LT555C.... but now I have a pretty good trigger waveform....
It would appear that something else is causing the 555 to have no output... Still!! If I manually trigger it, it has an output!!!....
ericgibbs ..... What should I be seeing on the Threshold / Discharge pins whilst acting as a monostable... I only get 0v... permanently.. Reset is high and cv is tied to a decoupling cap.... When simulating the output mimics pins 6 and 7...
This maybe where the fault lies..... I have 35k resistance to 2.5v but I cannot determine which cap is to ground.... If I don't get a pulse on pin 6 and 7, I'm not going to get a pulse on pin 3... BUT!! shorting pin 2 to ground fires pin 3.... I dont get it... The pulse looks good enough to trigger the 555????
