LCD font generator app for type 0 fonts

Open Camarine11 opened this issue 3 years ago • 3 comments

Hi

I have question about what app for LCD font generator can be used to generate new type 0 fonts. Can I use the free LCD font generator from MikroC? If this app is not good for this what app or online LCD font generator to use?

I need to make a 51 or 55 pixel height font with low spacing (eliminate all vertical and horizontal lines with white pixels) to fit 5 characters on a 1.3 inch SH1106 128x64 oled screen. LCD font generator from MikroC is nice app that shows the font image but did not work for me.

Found next in font_format.txt - type 0 fonts support only ascii chars with codes 0 - 127, and extended chars with codes 128 - 255. These fonts can be generated with LCD font generator ONLY.

Thank you

Hi @Camarine11

There is font online compiler, kindly provided by @RoboDurden: https://pionierland.de/fonts/index.php

As stated here: https://github.com/lexus2k/lcdgfx/wiki/How-to-create-new-font-for-the-library#creating-new-font-using-GLCD-font-creator-fixed-width-fonts, you can use LCD font generator from MikroC to generate new fonts for the library.

Please, use new format option of fontgenerator.py script to eliminate all empty vertical lines.

If anything doesn't work, let me know

Hi lexus2k

Thank you for quick answer.

I tested as follows and had partial success:

Used Arduino IDE v1.8.13 set to Arduino Pro mini 3.3V 8Mhz and SH1106 128x64 screen with lcdgfx library v1.1.1 installed and USBasp programmer. Used Python 3.6 with PIP 21.2.2, freetype-py v2.2.0 and freetype.DLL v2.11.0 made for Windows.

  1. Generated the large font with MikroC GLCD and tried running the python script as per wiki python fontgenerator.py --glcd glcdfont.c -f old > ssd1306font.h

I always get next error (this might be because I use Windows version of the Python):

Traceback (most recent call last): File "C:\Users\RMPC\Documents\Arduino\libraries\lcdgfx\to , line 176, in source = glcdsource.GLCDSource(fname, fsize, "utf8") File "C:\Users\RMPC\Documents\Arduino\libraries\lcdgfx\to e.py", line 79, in init bitmap[y].append( (bytes[row] >> bit) & 0x01 ) TypeError: list indices must be integers or slices, not float.

This is the content of the glcdfont.c file from GLCD I used:

  1. Tried creating Fixed width font from ttf font file suing the python command: fontgenerator.py --ttf impact.ttf -s 40 -g "0" ":" -f old > ssd1306font_py.h

This worked fine and resulting font displays fine on the SH1106 screen.

  1. Tried creating Variable width font from ttf file -> this produced the font file ok but I get garbled data on the olded screen. Used next command: fontgenerator.py --ttf impact.ttf -s 40 -g "0" ":" -f new -d > ssd1306font_py_n.h

Testing I found I get garbles data on SH1105 screen even when using built-in variable size fonts type 0x02: I used free_calibri11x12 from fonts.c file and still getting garbled data on the screen. I get garbled data when using any font created by fontgenerator.py using the -new format command.

Had similar result when used the font file generated by online tool from https://www.pionierland.de/fonts. Since I also get garbled data with built-in font type 0x02 I think the online tool generates the font file code correctly.

Used this type of code in the Arduino sketch to test the type 2 font:

    display.setFreeFont(free_calibri11x12);
    display.printFixed(0,  8, "Hello", STYLE_NORMAL);

Cheers
