Description
This command does control the LEDs present on some PCB AVR cards and shows some nice effects.
Effect type 0x01 does switch the LEDs specified in P2 on. Each bit controlls one LED. Which LED is controlled may be card dependent. Currently bits 0 - 6 control the leds beginning from the left, when looking down at them with the contacts to the top.
Effect type 0x02 does implement a runlight with the left 4 LED block. It may need adjustment on other cards to select the correct LEDs.
This command is only enabled when setting CONF_WITH_FUNNY to 1.
