TIL: the ( badge) got a few firmware updates since then – in addition to attempts to use it for covid contact tracing(!), they also feature battery life improvements and a new watch app that turns on the screen based on movement (only show the time when you need it) \o/

Does anyone have a / / @card10badge they're no longer using and willing to sell? Thanks!

I took the Control Center app for the that Niklas Roy wrote, and fiddled with it for so long that almost no byte is left where it was before:

badge.team/projects/control_ce

(alarm) clock, calendar, flashlight, compass, and weather station, all in one.

Pushed an update to my framebuffer repo. Now with font file library, including a toolchain for fonts in the Frank Abelbeck font file (faFF) format.

My font library also speaks a very basic printf dialect! I've added a large digit font, too.

Well, finally (after months of reinventing the wheel) I've all tools ready (png, surface, font) to write a... drumroll... clock .

I've completed work on my font toolchain. Creation and checking now possible via one CLI program. It can simulate font rendering, too (see screenshot). Just some more QA and I'll push it to my repo.

Guess I can call that beta state... Showcase/test rig of font rendering with clipping. The rectangle is the new surfaceBlendPosition() function at work.

First alpha of my bitmap font library.

Yes, I know that G abd M are missing -- forgot to define them in my font file. At least the replacement character (U+FFFD) mechanism works.

Good news! I completed work on my bitmap font format. Features: definition of any unicode character as column-oriented bitmask (up to 256x256*); lookup via a pre-compiled minimal perfect hash table (i.e. looking up any char always takes constant time).

*) previous tweet said 64x64, but I'm working on that.

Created a new : triangledemo. A rotating, flat-shaded cube, demonstrating the new triangle drawing routine of my surface library.

Update: now my surface lib can draw pixels, lines, circles and arcs. All surface-modifying functions record their changes in a new data structure. This allows more efficient surface redrawing. github.com/FrankAbelbeck/card1

surfacedemo update: now consistently themed...

Behind the scenes: I had to create a variant of my library for this crawling text. The original library ignores the projection part of homogeneous coordinates, significantly reducing the computational load of the matrix magic.

Finally! PNG reader and surface/framebuffer libraries work as expected. I'm cleaning up the code right now, so I can update the repo tonight.

@card10badge I can build a , but when using math.h float functions (fmodf, sinf etc) I get undefined references. I can resolve these with -lgcc. But then the l0dable freezes when calling any float math function. My firmware fails to boot, too. (used official v1.14 to run the l0dable)

My current toolchain setup:
cross-arm-eabi/binutils-2.33.1
cross-arm-eabi/gcc-9.2.0-r3 +libssp +vanilla
cross-arm-eabi/newlib-3.1.0 +nano

I am at a loss.
