We are updating the previous post on drawing text, since we realized we needed to fix a major display bug in pixel locating the text. In addition to that we updated the API for drawing text to return a bounding box around the drawn text so that the developer can know the pixel coordinates of where the text was drawn in the framebuffer. We also updated the bit-dump API to optionally add color to the terminal output.

In this blog post, we demonstrate how we have used FreeType2 to draw
text on the screen using fonts that can be installed using your Raspbian distro
packages. FreeType2 provides an easy way to render any type of supported font on
the screen, and we encapsulate all of that in a single function call
ssd1306_framebuffer_draw_text().
