P16F1827 and LCD Problems

[mister_e]

Now how about sharing it for humanity purpose

Hello BobW

About "your" MikroC Pro program ...

1) are you sure it has been written ( by you ??? ) for a '1827
2) did you create a project ??? ( the " module " error comes from here )

once " trimmed " it gives :

1198 ROM .... should compile fine with the demo version, no ???

[HUMOUR ON]

How much with PBP ????

nooooooo .... not on the head !!!

How much with PBP ????

With PBP, give or take a few:
Program Memory Words Used: 285
Program Memory Words Free: 3811

Give or take a little. So, about 7%, compared to MicroC's 29% used.

Now, this is not a fair comparison, because I don't know what MicroC's test program you are using, or what it does. PBP numbers are for just printing two variables to an LCD display.

Hoooooo ...

See #4

Program just reads voltage on ADC channel 2 , prints a text on line one of the LCD and prints the ADC voltage in V.VVV format on the second line ... of course with the Unit !

Comparison is not unfair at all as the shortest MkC Pro available way to display numbers is used here ...
you had also noted the LONG type use for "calculations" ... unavoidable with MkC.

I already made a comparison on this Forum and result was similar ...
PBP and Proton were quite the same for the result.

I am not sure which program you are referring to?
The one That gave me the display was written by me on a PIC16F88 using C.
I gave up on the 16F1827 do to lack of programming knowledge and lack of sample programs for that chip. Now that I have a somewhat grasp on the basics, I have been able to read and display the ADC value of a pot, (will use that later to read 3 switches on one pin).
It is all the PIC dependent declarations at the very beginning of the program that trip me up.

You have to crawl before you walk, and I am starting to crawl pretty well.

Without any further notice we all were on posts #1 and #3 ...

Of course result was not exactly that expected with #3 program ...

So, comes the killing question ...

Did you notice we're aboard a PICBASIC PRO ( MeLabs brew ) forum, and we are supposed to "speak" Basic ???

me too ...

Yes I do know this is a BASIC forum.
My post was only to thank those who were trying to help me get started.
