Array string must be ByRef

Thanks

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

Currently you have your array size at 3840 (128*30) ? Now you need to make array that is 128*40 = 5120 and then save only 6 bits per byte.
I guess you are currently reading 8 bits one by one from the bitmap and then saving the byte to the array ? Now you need to read only 6 bits at a time and leave the 2 bits empty. I hope I've understood right how you are doing it now.

Exactly, now i have a 3840 (128 * 30) array. Ok i will try with the 5120 bytes array, with 6 bits, per byte. Later i will comment the result.

Thanks

:? :? :?

Well, Henri, with an array of 5120, my display it's equal than with the 3840 array, 8O 8O 8O 8O 8O .

Well, I create a matrix of 5120 with a BMP, with the FAST LCD Designer (first i convert it to a file of hexadecimal values, and then i fill the matrix).

With the matrix that i have created, I use this function to fill the LCD:

Code:
    Public Sub sbrDrawLCDHex(ByVal pvstrPoints() As String)
        Dim shtAdreça As Short
        Dim shtcont As Short

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



Do you know where is the problem ¿?

Does the Fast LCD Designer save the data in 6 bits per byte format ?

When you save the bitmap in a BAS archive, you can put 6x8 or 8x8.

I supose that if i put 6x8, the lcd designer will save the file with 6 bits, is it ¿?

Well, we supose that the file is in 6 bits per Byte. My display doesn't work properly too... :? :? :? :? I'm so desanimated ! ...

Thanks

Did you save it as "Image" or "Image array" in the Fast LCD Designer ? I just did some testing and first tried to save as array but got some strange results. Then I saved as 6 bit Image and the file looked like it could be ok.

Yes, I save the file like Image, and with a 6X8, and the result is the same. Two posts ago i put the code that i use to display the bimpat, could be the problem there ¿?

It's very frustating ! 8O 8O 8O 8O

Thanks

I had a look at the code but didn't notice anything special. But as I know nothing about VB I might not even notice if there was some problem.
