LCD BARgraphs

[Darrel Taylor]

Like Alain said way up there.

Due to the spaces between the characters landing on an Odd number, vertical bargraphs on LCD displays don't work very well.

Bummer!

Hi, Darrel

Could you explain those lines to me :

ASM
lines = 0x10000001 ; Define the Styles
boxed = 0x10000002
blocks = 0x10000003
ENDASM

(From LCD_Bar.inc ) ...

My MPLAB 7.30 seems not to understand it ( comes in red ) ... nor me !!!

Hi Alain,

Those just assign some unique ID's to the words lines, boxed and blocks.

I used numbers outside the 16-bit range of PBP just to minimize confusion for myself. Then when PBP uses the number, all it sees is 1, 2 or 3.

I haven't bothered downloading the latest MPLAB so I hadn't seen any problem yet. But it should be ok to just make them 1, 2 and 3

ASM
lines  = 1                            ; Define the Styles
boxed  = 2
blocks = 3
ENDASM

Hi Acetronics

I had the same problem, when you use the macro, be careful about the letters upper and lower case thingy, I mean Blocks and blocks are different when you use MPASM. Darrel wrote blocks in LCDbar_INC file in the difintions, so you have to use blocks, not Blocks in the macro, the same applies for lines and boxed. This worked fine for me.

For example:

' In LCDbar_INC file you will find the following definitions that darrel wrote:
ASM
lines = 0x10000001                            ; Define the Styles
boxed = 0x10000002
blocks = 0x10000003
ENDASM
' No need to change them nay way...

In your code, you will use this macro:
;  BARgraph   Value, Row, Col, Width, Range, Style
@ BARgraph  _VOL_L,   2,   0,    20,   255, Blocks    ' Doesn't work

;  BARgraph   Value, Row, Col, Width, Range, Style
@ BARgraph  _VOL_L,   2,   0,    20,   255, blocks    ' Works fine

In order to change to Blocks, Lines, and Boxed. Instead of block, lines, and boxed, you have to change the following in LCDBar_INC file:

ASM
Lines = 0x10000001                            ; Define the Styles
Boxed = 0x10000002
Blocks = 0x10000003
ENDASM

And this too:

    if ((Style >= Lines) & (Style <= Blocks)) ; Is Style a valid constant ?
        MOVE?CB    Style, _BAR_style
    else                                      ; NO, treat it like a variable
        MOVE?BB    Style, _BAR_style
    endif

After that you can use Blocks, Lines, and Boxed in your code macro.

Seems like a lot of work to rewrite a program to use a different Case, when you can just turn off case sensitivity for MPASM, and use any case.

For MicroCode Studio Plus:

From View | Picbasic Options... | Assembler Tab and Options tab
uncheck the "Case sensitive" Checkbox
Press OK

The Microchip MPASM checkbox must be checked to see the Case option.

For other editors, or dos:

Add -c to the MPASM command line.

Hi darrel

I could have said that, as a matter of fact, being careful about letter cases while writing a code, prevented me of throwing that note about "uncheck the Case sensitive Checkbox", thats all darrel,

I have never used an include file other than the ones provided with PBP. I am getting an error trying to load the include file from Darrel. The only thing I can think of is that I have it in the wrong place. Can someone tell me where I have to put it?

Thanks,

Chris
