As you can see it does work to me! If It doesn't to you is possibly because of your project setup but we can't help without looking at your project. So, please attach the full Proteus project (the .pdsprj file, no simple screen shot) including the full (and possibly correct) source code. screen shot...

Sorry, but it turned out that you are using an illegal (cracked) copy of Proteus and as such, we won't provide you with any support.
Please contact support@labcenter.com and purchase your Proteus copy.

We can't know it without looking at your project. Please attach the full Proteus project (the .pdsprj file) including the source code.

The watch window shows the internal registers values of the HC11 core only, i.e. U1 in the "HC11 Evaluation Board" sample project. So, the PORTB/PORTC registers values in the watch window are referring to the ports embedded in U1, the 68HC11 not U12, the 68HC24. In the HC11 Evaluation boar...

I'm glad it works.

Maybe you didn't enable the low peripheral interrupts. Anyway, I attach a simple test showing the priority interrupts just in case of two coincident pulses. I alaso attach the source code in the post and schematic screen shot just in case you don't have the latest Proteus version. test.pdsprj /* Mai...

Yes, you have old version.

It works with anything is in the Source Code Windows, provided you select Display Disassemby, Addresses and Opcodes...and use a recent Proteus version.

In the Source Code select all the code - with keyboard: Shift + Down or Shift + Page Down, with mouse: click left button and drag selection down. When all code is selected press CTRL+C (standard Windows copy) and press CTRL+V or Paste into NotePad or whatever editor. Then you can print it on paper o...

Could you please attach your "test-adc.pdsprj" project file here ? So that I can have it a look at.
Thanks.

Double left click on the ATMEGA328P part and select the PCB Package from QFP 32 pins ... and change it to SPDIL28.

The middle and last circuits are not the same at all. They become the same only when you disconnect the ground from the pot of the middle circuit.

Ok. You have set the Interactive Simulator Options to "Setting for Better Accuracy". This is not suggested set for such a simulation. You need to set "Default Setting" or even better "Settings for Better Convergence". OK Immagine 2023-07-13 185847.jpg WRONG Immagine 202...

jayanthd2k17, Both files work fine to me with no gmin error BUT they are both based on MOC3031M; didn't you start the topic talking about MOC3021?? I want that circuit no the MOC3031. If you give fragmented and contradictory information I cannot carry out any troubleshooting. If you want I fix anyth...

I tested the circuit exactly as it is above and it works with CHASSIS, no Gmin error. So post the project file, no the picture shot. I suspect that circuit is part of a larger one.
