Documentation on Hackaday.io. In action: YouTube.

Pattern generation

The displayed pattern is hardcoded into the program. You can either manually edit the bitpattern in pov.c (const uint8_t data[] ...) or include a generated C file.

See banner1.txt for a template for the generated C file. "X" is LED on, " " off. The awk script will generate a C include from it

./banner_txt2c.awk < banner1.txt > banner1.inc

or just

make banner1.inc

Compile, generate pattern and flash with usbasb programmer

make flash
