Just FYI, since I've implemented something similar in Swift, using the PWM you would have had to implement more or less the same algorithm, i.e. changing the duty cycle of an high frequency signal to generate these "slot-based" patterns that identify the 0s and 1s of the WS281x (there are minimal timing differences between the variants) protocol. Note: God bless the Oscilloscope, essential for these projects. |
