LCD BARgraphs

[Christopher4187]

I tried everything and it still doesn't work. I have it in the same folder as the main program. I'm stumped.

[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.
