BMP monochrome

[maxtisc]

Hello
a question for the team
in block GLCD you can enter the print function BMP image read from a sd card for monochrome displays (type KS0108)?
in the forum and in the examples it is always a color display, or you have a sample file that does this?
thank you

Hello,

Yes outputting a monochrome bitmap to a monochrome graphical LCD should be fine.

You can use paint to save a bitmap file with a monochrome colour depth. It's then just a case of parsing the file and getting the pixel data.

The colour examples should be a good starting point. The wikipedia page on bitmaps should also help you with the parsing the monochrome file format.

hi benj
to do the tests I used your post http://www.matrixtsl.com/mmforums/viewt ... fat#p36423
which is very informative but I came to a point that I can not get past, now I can read the mmc and see the display characteristics of the stored images (width 128, height 64, BPP 1, comp 0, offset 62) but I do not see the picture, I see only that the screen fills from bottom to the top.
I tried to change the flow PBB 24 to 1 and eliminated the part about reading color, but had no effect
You can help me?

Hello,

I have had a bit of a play with your code and this now seems to be working to display the bitmaps correctly.
