AC Simulation Oscilloscope and Signal Generator with Fritzing

[fai]

Hi,

To use transitory analysis, you need to star fritzing in debug mode and then add the oscilloscope or launch a transitory simulation (choose that in it small arrow of the simulation button).

Check an example of a 555 circuit and detailed instructions of how to launch fritzing in debug mode here:

Using 555 timer chip doesn't work

Steps I took that resulted in the problem: Created a simple timer circuit with a 555 timer chip. Started the simulation, LED does not flash, just stays steady on. In the console, i get an error over and over again: SendCharFunc (libId:0): stderr Error: vector time not found! … What I expected should have happened instead: LED light should flash on and off and no error should occur in the console … My version of Fritzing and my operating system: version 1.0.4 of Fritzing on Ubuntu 24.10 … …
