Led Controller (LED controller) is through the chip processing control LED light circuit in each position of the switch.
The controller controls the driving circuit according to the pre-set program to make the LED array emit light regularly, thus displaying words or graphics. Led Controller, with MCU, DSP, FPGA as the processor, add interface i/o circuit, write the corresponding program code, deal with the protocol of LED driver chip, to achieve control switch and PWM duty cycle, to achieve full-color changes, can display animation, such as flowing water, gradual change, jump, video, etc. .
