annotate Scan/ISSILed/led_scan.c @ 384:82ce1988fefe

Adding basic ISSI led brightness control capabilities - 6 modes * Single led: decrease, increase, set * All leds: decrease, increase, set - Currently update speed limited to once every 30 ms * Likely an I2C driver or ISSI limitation preventing even faster updates
