Abstract
A method of transmitting data serially can be provided by generating a pulse for a current data bit on an electrical conductor coupled to a string of LEDs, where the pulse has a pulse duration that is defined by a time between a rising edge of the current data bit and a falling edge of the current data bit, that is based on a logical value of the current data bit. A random delay time can be introduced between the falling edge of the current data bit and a rising edge of the next data bit and then the rising edge of the next data bit can be generated after expiration of the random delay time.
