This scheme adopts pl51wt003 chip, which integrates 16kb flash, 256byte true EEPROM, 8 + 8-way 11bit ADC, 6-way PWM and other rich resources. At the same time, pl1166a RF chip is integrated on the chip to realize wireless remote control and other functions; The scheme collects the current of each lamp bead in real time to achieve the accurate closed-loop control of lamp bead current, which can effectively avoid the problem of brightness reduction caused by long-term use of lamp beads;
1、 Scheme performance characteristics
1. The main control chip pl51wt003 has rich resources and high integration;
2. 11bit ADC module to collect the current of each lamp bead in real time;
3. 6-channel PWM output, configured with AD value to accurately control current output;
4. 16kb flash program space, which can optimize a variety of compensation algorithms;
5. Integrate RF chip to optimize design cost.
