CapMeter (PIC16F628) simulation crashes under MacOS 12.7.6

#1 · August 17, 2025, 8:53 pm

Hello,

I am new to SimulIDE and tried to simulate the Roman Black Capacitor Meter.
I drew the schematic and loaded the PIC16F628 firmware, but the IDE crashes everytime I start the simulation (both under versions 1.0 and 1.1).
Can someone tell me what's wrong ? I am attaching the SIM and HEX files.

Thanks a lot.

Hi.

Thanks for reporting.

The crash is because a bug in 16F628 comparator 1 mode 6.
It will be solved for next tester build: https://simulide.com/p/testers/

As a side note, you need to actually connect ground to LCD RW Pin:

Hi,

Thanks for your quick reply.

I added the missing ground connection. Can this be automatically done when two items pins touch ?

You can connect 2 pins by moving them together while pressing Shift key.
