I'm thinking of building this simple L/C meter.

I've never used an LCD with a PIC before, so for the display LCD what should I be looking for? They are using a 16 x 2 LCD AMPIRE AC-162D for the L/C meter.

Would this be a suitable substitute?

What I'm trying to avoid is modifying the existing code which is on the first web site. I'm looking for an inexpensive solution I could put together quickly.The only thing I dont have is the display.

The LCDs look interchangeable and I've not come across any with this pin out that aren't.

Indeed, IME they all use the same controller chip set (Hitachi HD44780

  • HD44100, IIRC) or very close clones, so most should work.

OTOH, VFD and OLED displays that claim to be compatible often have subtle differences in timing etc.

Also, it's not impossible in a 'hobby' project that the code is not written to meet all the specs, but chances are it will work.

I'll order a couple of them then.

Thanks for the replies Spehro Pefhany and Raveninghorde.
