Just noticed that Emil has deleted all his posts in this thread. So I guess there's no need to retrieve the missing posts from backups :wink:

Buff, there are something that don't run ...

When I clear the LCD, or when I draw bitmaps, there are some pixels that doesn't paint. It's like the functions doesn't be good, or something else, but i'm cracking up !

I want if someone has or had the same problem and have solutiones, how can solve this !!??

Thanks.

Are you using busy flag checking ? Or maybe you could try a delay instead of that.

I use the functions that you posted here, i think that doesn't use any delay.

Example:

Code:

Public Sub ClearLCDGraph()
        Dim shtCont As Short

        WriteData(G_BASE And &HFF)
        WriteData(RShiftLong(G_BASE, 8))
        WriteCtrl(&H24) 'address pointer to G_BASE 

        For shtCont = 1 To NUM_PIXELS
            WriteData(0)
            WriteCtrl(&HC0) 'write data and inc ptr 
        Next
    End Sub

Other example:

Code:

    Public Sub sbrDrawLCDHex(ByVal pvstrPoints() As String)
        Dim shtAdreÃ§a As Short
        Dim shtcont As Short

        shtAdreÃ§a = G_BASE '+ (0 * BYTES_PER_ROW) + (0 / 6)
        WriteData(shtAdreÃ§a And &HFF)
        WriteData(RShiftLong(shtAdreÃ§a, 8))
        WriteCtrl(&H24)
        For shtcont = 1 To UBound(pvstrPoints)
            WriteData(CInt("&H" & pvstrPoints(shtcont)))
            WriteCtrl(&HC0)
        Next
    End Sub

The delay and busy flag checking, if used, are in the WriteData() and WriteCommand() functions. Have a look at the first C code I posted to this thread.

Hi! The WaitDisplay Function in WriteData and in WriteCommand, i decided not to use it, because doesn't seem to be run with my LCD, it writes worst, and i have the same problem of non drawing pixels (a few).

I think it's problem of adresses, but i'm losted.

Thanks

You could try putting a delay in place of the WaitDisplayReady().

The waitDisplay function don't make a delay Â¿? I think tht this don't seem to be a delay problem, because all are drawn except a few bits. -_-'

I'm being crazy, whats possible that there are pixels that don't draw !!!

. And when i'm trying to display a whole image in Hexadecimal values, it seems that divide the lcd display in two.

Example:

This is the LCD
|------------------------|
|Â·Â·Â·Â·Â·ccccccÂ·Â·Â·Â·Â·Â·Â·Â·Â·Â·Â·ccc|
|Â·Â·Â·Â·Â·ccccccÂ·Â·Â·Â·Â·Â·Â·Â·Â·Â·Â·ccc|
|Â·Â·Â·Â·Â·ccccccÂ·Â·Â·Â·Â·Â·Â·Â·Â·Â·Â·ccc|
|------------------------|

This is the BMP
ccccccc
ccccccc
ccccccc

It's like divide the display, i don't understand anything :evil:

I hope you understand the draw.

Thanks

How many bits are you trying to write in one byte ? If you have your display set for 6x8 font you need to send 6 bits in one byte.

I'm putting 8 bits, but you're right, the font is set to 6x8.

This will be that I've to put only 6 bits, right ?

But then, how i can do this Â¿? If I have "FF" value this can't be represented only with 6 bits !!??

Thank you
