Graphical Displays with PBP3

[rocket_troy]

Well, there's 2 things I never considered - (1) using the upper 4 data lines for transfer and (2) grounding the unused.
It's probably worth mentioning (for a heads up to others) the display I'm using has a serial/parallel 3 pad jumper on the back that was soldered to parallel setting as purchased. I needed to change that to serial in order to operate in serial mode. Whether that eliminates the need to pull/push the PSB pad I never bothered finding out - I just assumed the PSB pad still needed setting.

edit: just after posting that I realised that jumper is probably a direct link to the PSB pad to push or pull - duh.

Richard,
Is it a big deal adding a character like a colon to the large font table? Working out the dot matrix for the character should be pretty straight forward, but not sure about the indexing and whatnot?

Thanks,

Troy

you can use your own fonts Generated by MikroElektronika GLCD Font Creator 1.2.0.0
the font headers have some basic details on how to pbp-ify MikroElektronika fonts

I've just tried that but I'm confused: I can pick a standard font and make something up from that using the tool, but what do I do then? Do I "export" it? Exporting, produces the matrix of hex codes for the font graphics but that's all it produces. The largenum and bigchar files you included have many lines of headers? footers? whatever... above and below the font dot matrix codes and the export button that I'm clicking doesn't appear to generate any of that and it's not really clear what those lines are?

Regards,

have a look here

Thanks. That link eventually lead to the TFT export option needing to be visible to click on. Alas, that appears not useful without some kind of description of what those headers represent. Intuitively I would've thought they'd be some kind of memory addressing but they can't be. The 1st column looks like the font width but no idea what the second byte represents?

you need to be more explicit, i cannot see the problem

here is the raw " C " code as exported for chrs 48 to 60 as 11 x 16 sized font

you simply need to make it comply with pbp limitations , thats it you don't have to understand it
its pretty simple anyway

0x00, unused
0x00, unused
0x30,0x00, first chr
0x3C,0x00, last chr
0x10, height
0x00,

0x0B,0x3C,0x00,0x00, width of chr1. offset to font data for chr 1
0x0A,0x5C,0x00,0x00, width of chr2. offset to font data for chr2
0x0B,0x7C,0x00,0x00, width of chr3. offset to font data for chr 3

post#1

i wrote this graphics lib to handle led dmd's [1/4 scan dot matrix displays] in mono, red/green or rgb in varing sizes up to 128x32 pixels.
it occured to me that with a little more effort it would make a general purpose graphic lib for nearly any display. so here it is.
it uses mikroe fonts that you can easily generate. the variable width fonts can be up to 23 bits wide if you like.

no guarantee 24 bit wide will be reliable either

[rocket_troy]

Okay, so fixed widths can have a wider limitation?

Troy

[richard]

no there are no fixed width fonts not that that would alter anything.
the mask is 32bits wide that is used to insert the font row data into the graphics frame memory, 23 bits font + 8 bits to allow insertion at any bit point offset + 1 clr column between chars = 32 bits. to get to 24 bits the mask would need to be 48 bits wide [needs 16 bits to allow insertion at any bit point offset], the code size would double the speed halve. any font over 23 bits wide will intrude on its neighboring chars space at some bit offsets

[rocket_troy]

Thanks Richard, that clears that up. No biggy anyway.

edit: actually the one working fine was 18x24 (I was mixing up the width & height)
