Rust Bare Metal NeoPixel led not working on ESP-Buddy

[georgik]

The LED is has inverted signal.
There is no implementation on bare metal due to missing InvertedPin: esp-rs/esp-hal#178

Signal is inverted probably because of transistor used for driving 5V NeoPixel input from 3V3 ESP32 output, but i can't find any schematics of ESP-Buddy to prove this.

Hi @lada1k . That's correct. Still we're missing Rust Bare Metal implementation of Inverted GPIO to get it working with Rust.

@bjoernQ succeeded in creating working prototype for the board.
Following issues are blocking this feature:

• Wrong timing in smart-led-adapter esp-rs/esp-hal#855
• https://github.com/bjoernQ/esp-hal/pull/1/files
