raw display access
over 50 FPS
1), nice for viewing bargraphs
nearly 500Hz refresh-rate
making use of cool custom VDR displays
using a dual-access SRAM (writing and reading)
writing to SRAM via USB endpoint zero-calls
no kernel module, using libusb via usermode
special commands for changing the brightness
low-cost parts
RegExp used
G[0-9]{1} are gates, counting starts on the left side
[a-e]{1}[0-6]{1} are points of the dot-matrix
italic items are unnecessary (cos they've been occured already)
*bold* itmes are special segments, explained later
H+ and H- are for heating the display (~3V)
