LCD showing mostly jibberish on 16F716

[Scampy]

I must admit I'm surprised that it doesn't have a built in oscillator. Thought that all pics had that ??

Hi,
Actually, according to the product selector on Microchips website only 18 out of around 375 models (which are in production) is missing an internal oscillator of one type or another. They are:

PIC16F54
PIC16F57
PIC16F716
PIC16F59
PIC16F1454
PIC16F1455
PIC16F1459
PIC16HV540
PIC16F818
PIC16F819
PIC16F72
PIC16F73
PIC16F84A
PIC16F74
PIC16F76
PIC16F77
PIC18F6520
PIC18F8520

So it's close but not quite all ;-)

/Henrik.

I have used both the pic16f818 and 819 which are in the list. Both have internal oscillators to 8mhz.
Microchip has one of the worst website/search engines out there.

That's just weird, selecting No and None in the Internal Oscillator column of the product selector produced the above list. Checking the 16F818 does indeed show it's got internal oscillator.
Thanks for pointing that out Mark!

I cut my teeth on the 16F877 and it is my understanding it does not have an internal oscillator. And it doesn't seem to be in your list Henrik.

[HenrikOlsson]

That seems correct.
Conclusion: The list is flawed and so is the data Microchip is using in their selector tool - which is what generated the list.

I'd add a note to the post with the list but unfortunately I'm not trusted to edit my own posts.

Sorry for the confusion.

/Henrik.

All is good. I'm just glad I'm able to shift some of the blame from myself to Microchip in this instance.. haha

Thanks for all the help anyway circuit now working like it should, now back to finishing the code....
