Does anyone have a #card10badge / #card10 / @card10badge they're no longer using and willing to sell? Thanks!

Still can't get my arm-none-eabi toolchain to compile a #card10badge firmware that boots.

binutils-2.33.1
gcc-9.2.0-r3 +libssp
newlib-2.5.0 +nano

My #l0dable compiles and runs as long as I don't call certain library functions (like printf with string conversion or math stuff) -- such things freeze my app. epic_file_open() stalls, too.

I don't have debugging hardware, so I have to dissect the elf files. I suspect incompatibility with my newlib nano instance.

@card10badge

The newest version of my #card10badge #l0dable applies an affine transformation matrix during image composition. This means the sprite can be moved, rotated, sheared, scaled, squeezed etc before painting it onto a surface. LEDs show a cycletime of approx. 20 ms.
