Pulse Width Encoding Protocol

which is widely used on led strips.

Named by me and is not responsible for any thing -.-

Backend difference

RMT

• Very very accurate timing.
• Currently cannot take use of DMA and is heavily depending on ISR routine, which makes it quite unstable when higher proority tasks are running (such as WiFi).
• Able to simulate Dshot timing.

SPI

• Minimal step resolution is limited so that it is expected to have some timing difference between real output and desired output.

• Can take use of DMA and is reliable for great amount data to send.

I2S

Examples

There are currently two examples under the repo:

Dshot ESC control

in examples/dshot_esc_ctl

Only supports RMT backend

LED strip

in examples/led_strip
