PIC16F506 Problems

WOW!
I don't ever remember seeing that documented anywhere.
Thanks Bruce.

I guess that kills it for the 16F506 on this project...

Cheers

It's in the 2nd paragraph in the manual under LCDOUT, and in older versions of PBP new.txt docs.

12-bit core has very limited support due to limited resources on the PIC. If you're using these, it's best to keep it as simple as possible since these device types have very limited RAM and stack resources.

You can normally find a 14-bit core type really close to same price range.

Thanks Bruce,

I don't know how many times I have read the LCDOUT section of the manual without seeing that caveat (or at least have it sink into my brain). A valuable lesson learnt!.

I will change over to using a PIC16F684 - pin compatible, does what I need it to do and is less than a dollar more expensive.

Thank you to all who have assisted me in my endeavours.

Cheers
