This is a small 5x7 bitmap font I found on the internet. It looks like
This package contains the font in C array
Here is a C program which prints out a range of the
above characters in column-first format, useful for OLEDs and such.
More Fonts for OLEDs
I wanted to use a Heltec OLED and the tiny font I used above was too small
to be comfortably read. So, I started looking for new fonts. I found some
These fonts aren't constructed very nicely, but they are OK for a personal
project. Anyway, I wrote a little code to convert and use these fonts
on a Heltec 0.96" OLED using an Atmega8.
The last one is a program which takes the converted fonts and generates
code to display them on an Atmega8. The input to the program is a simple
text file which includes one command per each line. The generated code
contains functions to communicate with the OLED as well as functions
to display a given character using different fonts. Here is a sample
R 32 32
An input file consists of blocks. Each block starts with the name of the font
file, given by the 'F' command. A block ends when the 'E' command is given.
This command specifies the name of the function which will display the
given characters on the OLED. Between these two commands, character set
specification commands must be given. These are as follows:
- S string Characters in the string are added to the set.
No whitespace or control characters are allowed in this form.
- C character The given character is added.
- R start end Characters between numeric values start and
end are added to the set. This is the only way to specify nonprinting
The output functions have no concept of any control characters. i.e. newline
doesn't switch to a new line, it just prints the character associated with
In addition there are two more commands.
