LCD BARgraphs

[mister_e]

can you post a whole screenshot?

It's working for me.

EDIT: i don't know if it's revelant but be sure your program path is short I.e C:\PBPprog\Project1

I thought PBP (especially when run through a DOS window) couldn't handle filenames greater than 8 characters...

Example 1...

PBP -p16F628 12345678 -v

The above WILL comple, the example below will NOT...

PBP -p16F628 a12345678 -v

Further... here's a gotcha...

Example 2.

PBP -p16F628 12345678 -v

Will compile the file 12345678.bas happilly...

Example 3.

PBP -p16F628 123456789 -v

Will NOT compile the expected file 123456789.bas but instead will access the file at Example 2 and compile that instead!

Then you would use...

<pre>PBPW -p16F628 123456789AndAFewMore.bas -v</pre>or use MCSP, it does it automatically.

But since you bring up the command line option, there's a few things that could be a possible problem. Path settings, current directory ...

Christopher,
Are you compiling by command line, or an IDE?

Here is a screenshot of my error. I took out the LCD stuff just to make sure that wasn't causing the problem.

Darrel,

I'm not sure how to answer your question as I still new to PBP. In the screenshot is how I complie programs.

If you click on the Include file in the Code Explorer on the left side of the screen, does it pull up the file? Or does it create a new file?

If it creates a new file, then the Include file is in the wrong folder.

It should be in the same folder as "Bar Graph.bas".

Darrel,

I got it, thanks for the help. The problem was that both files were saved as .pbp files. All of my programs are saved the same way and I have never had an issue.....until now. So, that part works but now I have another problem.

I have a 2X16 LCD set up on a development board. I have one simple LCD program and that works fine. I put the same LCD commands into the bargraph program and it doesn't work. I can see weird charecters displayed on the first line but nothing on the second line. Within those charecters I do see numbers every now and again and when I turn the pot, I can see the value change so I know it's functional but just not displaying correctly. Here is the program:

; Initialize your hardware and LCD first.
define osc 20

' Set LCD Data port
DEFINE LCD_DREG PORTB
' Set starting Data bit (0 or 4) if 4-bit bus
DEFINE LCD_DBIT 4
' Set LCD Register Select port
DEFINE LCD_RSREG PORTB
' Set LCD Register Select bit
DEFINE LCD_RSBIT 2
' Set LCD Enable port
DEFINE LCD_EREG PORTB
' Set LCD Enable bit
DEFINE LCD_EBIT 3
' Set LCD bus size (4 or 8 bits)
DEFINE LCD_BITS 4
' Set number of lines on LCD
DEFINE LCD_LINES 2
' Set command delay time in us
DEFINE LCD_COMMANDUS 2000
' Set data delay time in us
DEFINE LCD_DATAUS 100
'This setup will tell PBP a 2-line LCD is connected in 4-bit mode with the data bus on the
'top 4 bits of PORTB, Register Select on PORTB.1, and Enable on PORTB.0.





DEFINE ADC_BITS 8 ' Number of bits in ADCIN result
ADCON1.7 = 1 ' Right Justify AD result

INCLUDE "LCDbar_INC.bas" ' Include the BARgraph routines

Value VAR WORD ' Must be a WORD even though AD is 8bit

LCDOUT $FE, 1 ' Clear Screen
pause 500

Loop1:
ADCIN 2, Value
LCDOUT $FE,2,"Value = ",DEC Value," "

; syntax- BARgraph Value, Row, Col, Width, Range, Style
@ BARgraph _Value, 2, 0, 16, 255, lines



GOTO Loop1


Like I said, these LCD commands were copied word for word from another known program. Any ideas?

Thanks again for the help.

The DEFINEs don't match the comments. Might be the prob.

Defines show RS on PORTB.2, and Enable on PORTB.3

But, your comment says...
<pre>'This setup will tell PBP a 2-line LCD is connected in 4-bit mode with the data bus on the<br>'top 4 bits of PORTB, Register Select on PORTB.1, and Enable on PORTB.0.</pre>
