AI Technical Summary
Existing LED control chips, due to frequency differences caused by manufacturing processes and application scenarios, accumulate signal recognition and reshaping errors in series connection, which limits the number of LEDs that can be controlled and the signal transmission rate, thus affecting application scenarios.
A data signal processing device is adopted, including an input interface module, an intelligent signal frequency interpretation module, a data signal acquisition module, and a data signal reshaping and output module. The intelligent signal frequency interpretation module performs bilateral trigger sampling within the clock cycle to determine the acquisition confirmation bit and the end bit, adjusts the duty cycle of the communication protocol, performs signal reshaping and decoding, and ensures stable signal transmission.
Without changing the system controller signal input frequency, it automatically adapts to the processing of input data, improves the transmission rate, stably transmits more LED beads, and ensures the stability and consistency of the LED transmission process.
