NEC demonstrates how to control up to four HED LED channels

USA - NEC Electronics America ( http:// ) will, at Embedded System Conference 20009, demonstrate how to control up to four individual channels of HB LEDs, such as those used in the industrial market, using a DALI controller and a DMX512 controller.

The DALI protocol is popular for controlling office white light, while the DMX512 protocol is used in the atrical and entertainment lighting. These controllers send commands to NEC Electronics' 78K0/Ix2 MCU, which in turn, receives the commands, interprets them and drives the HB LEDs accordingly.
