    Looks good. I don't have lcd to try it out.
    I hope that you didn't write all user command wrapper manually.
    I posted app for that

    I am aware of your app but the base code for this preceded it , so yes it was a manual work
    I haven't done anything pbp wise with enough user command code in it to use your app yet .it seems that
    I have spent most of my time coming to terms with the mcc and xc8 lately . I don't see myself coming back
    from that exercise now . development wise C is just so much easier, I will still keep hacking away at pbp
    for now anyway.

    Thank you for posting an SSD1306 example, Richard. I'd like to bring up my 128x32 OLED display using a 16F1823 and XC8 with a 'retro' TIL311 type font.

    Cheerful regards, Mike

    Hi Richard,

    it's any possibilities to drawing a line like a progress bar?
    For example, I had ADVAL value from 0 to 120, and I want to draw line on OLED.
    I try this:
    Code:
    GLCDDHL 0,0,adval,1
    This didn't work because GLCDDHL accept only numbers not variables like ADVAL.

    It there any way to do it with your include?

    Thanks Richard, tomorrow I try it.

    And this probably for vertical lines:
    Code:
     ;----------------------VERT LINE------------------------------------        
    GLCDDVL?CCC  macro Xin ,Yin , Hin 
        MOVE?CB  Xin ,_gx 
        MOVE?CB  Yin,_gy 
        MOVE?CB  Hin ,_gl 
        L?CALL _xyy
        endm 
    
    GLCDDVL?BCC  macro Xin ,Yin , Hin 
        MOVE?CB  Xin ,_gx 
        MOVE?CB  Yin,_gy 
        MOVE?CB  Hin ,_gl 
        L?CALL _xyy
        endm 
    
    GLCDDVL?WCC  macro Xin ,Yin , Hin 
        MOVE?CB  Xin ,_gx 
        MOVE?CB  Yin,_gy 
        MOVE?CB  Hin ,_gl 
        L?CALL _xyy
        endm
    Right?

    I tried it, and it works for drawing smooth line from variable 0 to 120 for example, but if the value decreasing from 120 to 0 then I'm not able to clean the line without clearing the whole display and it causes flickering.
    Why I need that? I'm trying to make a voltmeter with bargraph.
    Here are the code snipet:
    Code:
    gosub glcd_init
    GLCD_CLR
    
    do
    for n=0 to 120 step 1
    GLCDDHL 0,0,n,1
    next n
    
    for n=120 to 0 step -1
    GLCD_CLR
    GLCDDHL 0,0,n,1
    next n
    loop
    It would be good to have variable option in all options like:
    Code:
    GLCDDHL  var1,0,var2,0
    GLCDDVL  var1,0,var2,0
    GLCD_CLR var1,0,var2,0
    It's that possible?

    I Think a new command is easier
    USERCOMMAND "GLCD_BAR" ;clear/SET area x,y,X1,Y1,COLOUR


    eg

    GLCD_BAR 0,0,var1,3,1 ;draw a horiz bar from 0,0 to var1 . three pixels wide
    GLCD_BAR 0,0,var1,3,0 ;clear a bar from 0,0 to var1 . three pixels wide

    or

    GLCD_BAR 0,0,3,var1,1 ;draw a vert bar from 0,0 to var1 . three pixels wide
    GLCD_BAR 0,0,3,var1,0 ;clear a bar from 0,0 to var1 . three pixels wide


    i don't have anything setup so this is untested, caveat emptor



    ps if GLCD_BAR 0,0,3,var1,1 is not right then
    GLCD_BAR 0,0,3,var1,255 might be needed

    an improvement if bar cmd fails
    Code:
    gosub glcd_init
    GLCD_CLR
    
    
    do
    for n=0 to 120 step 1
    GLCDDHL 0,0,n,1
    next n
    
    
    for n=120 to 0 step -1
    GLCD_CLR 0,0,120,1 ;is a lot more efficient
    GLCDDHL 0,0,n,1
    next n
    loop

    Thanks for reply,
    It doesn't work quite well. It draw four lines instead one line. For me is more suitable to have variables in usercommands like I wrote before.
    Code:
    GLCDDHL  var1,0,var2,0
    GLCDDVL  var1,0,var2,0
    GLCD_CLR var1,0,var2,0
    because in this case I can point exactly what and where I want to clear the line, or draw a for example 10pixel wide line and move it horizontally wherever I want with changing variables.
    Code:
    do
    for n=0 to 120 step 1
    GLCDDHL 0,0,n,1
    next n
    
    
    for n=120 to 0 step -1
    GLCD_CLR 0,0,120,1 ;is a lot more efficient
    GLCDDHL 0,0,n,1
    next n
    loop
    This solution I tried before as well, it still flicker if line goes from 120 to 0.

    i can't follow what your saying
    show some code of what you try an describe what you get or post a pic

    did you try new include file like this for narrow bar?
    GLCD_BAR 0,0,var,1,1 ;draw a horiz bar from 0,0 to var . 1 pixels wide ;//or
    GLCD_BAR 0,0,var,1,255 ;draw a horiz bar from 0,0 to var . 1 pixels wide

    while usercmd helps alleviate the turpitude of pbp's immutable condition when it comes to
    support for any peripheral devices/hardware module less than 20 years old.
    usercmd is by no means perfect, a macro needs to exist for each and every permutation of input term/s
    and that can be lots and lots of macros. i create only the ones i require ,its not difficult to
    add more . a close look at the error messages when compiling tells you whats missing if there is an issue


    pedja089 made this if you want an easy way to cover many bases

    I suppose you are aware of the Darrel's Bargraph include file (http://dt.picbasic.co.uk/CODEX/LCDBARgraphs). Isn't this enough for your needs?

    It took a little while to figure out how to do it, but finally I made it.
    Thanks for help to Richard. He pointed me how to modify usercomands for my needs. Endless possibilities to create a bargraphs, progress bars etc. On camera looks a bit flickery, but in real life no flicker whatssoever.
    Here a little demo how it works:

    Hello,

    I need help getting this to work. My oled display does not respond at all and appears off. I'm running the sd1306_demo_16.pbp program. Everything compiles fine. I'm using a 16F1619. Here is what I've tried so far.

    1. I tried both the old and newer i2c.inc files
    2. Confirmed the oled works by using it on an Arduino
    3. Confirmed the proper oled address with the Arduino (0x3C). I made the change in the demo.pbp file
    4. Ran blink LED program on the PIC16F1619 to verify functionality
    5. Tried at lower 4Mhz clock speed
    6. Checked Clock and Data pins with scope to make sure data was being output to the display, it is
    7. Tried two other oled

    I'm not sure what else to try. I've never used an include file before so maybe I'm doing something wrong. I put all the include files and font files in the same folder as the .pbp file location.

    Code:

    3. Confirmed the proper oled address with the Arduino (0x3C). I made the change in the demo.pbp file
    arduino use a 7 bit address pbp uses an 8 bit addresss , correct address to use is (arduino address)<<1
    0x3c<<1 = 0x78

    thanks Richard,

    I had no idea. I changed the address back to 0x78 just now and I still don't get anything on the screen. I get this ASM Warning in the results window after compiling. Not sure if it matters

    [ASM WARNING] SD1306_DEMO_16.ASM (400) : Found label after column 1. (GLCD_BAR?CCBWC)
    [ASM WARNING] SD1306_DEMO_16.ASM (432) : Found label after column 1. (GLCD_BAR?CCBWC)
