I would like to also know what is the state of this crate? It seems that a lot of good stuff is in this PR https://github.com/loyd/rscam/pull/30.

It would be nice if rumqtt could also support `pkcs8` private keys: https://github.com/ctz/rustls/blob/master/rustls/src/pemfile.rs#L69. This caused panic for me.

I am also very interested in knowing if it is still maintained.

Use case can be that there is a `no_std` lib that is primarily meant for embedded devices and it has bunch of `defmt` prints in there and you wanna use...

There is actually a lot of information in docs: https://docs.rs/stm32f4xx-hal/0.8.3/stm32f4xx_hal/adc/struct.Adc.html. ADC over DMA example can be found from https://github.com/stm32-rs/stm32f4xx-hal/pull/186

FYI: this PR should add support for non-blocking writes https://github.com/esp-rs/esp-idf-hal/pull/84 however it is not entirely tested yet.

I have added examples to documentation for the drivers that I have improved: * [can](https://github.com/esp-rs/esp-idf-hal/blob/embedded-hal-1-compat/src/can.rs#L5-L33) * [serial](https://github.com/esp-rs/esp-idf-hal/blob/embedded-hal-1-compat/src/serial.rs#L8-L35)

I can confirm that this fixes panic in such rtic idle loop: ```rust let mut t = monotonics::now(); loop { let now = monotonics::now(); if now - t >= Milliseconds(500).into()...

This fork allows to do it: https://github.com/marjakm/fern-rs/commit/29cead260804a4d192b2ade8ad374cf45f70c12c

I am OK with proposed changes.
