esp32-wifi's Introduction

esp32-wifi

NOTE: Superceded by esp-wifi.

A experimental wifi driver for the esp32 written in Rust.

Building

This crate uses the esp-idf binary blobs for wifi functionality. The C foreign function interface is generated with bindgen. This is done using the generate/bindgen.sh script, but only needs to be done again when the version of the binary blobs is changed.

The generate/bindgen.sh can be called from the root directory to create the various files in src/binary. The version of esp-idf used should match the version of the binary blobs in the esp32-wifi-lib sub-repository. (Currently version v4.1 of the esp-idf is used.)

esp32-wifi's Issues

Describe build requirements

Hi, I know this project is very early-days, but I was hoping to help work on it, but it's really hard to get building. First I tried rust 1.48.0, but changes to the unstable bits of the alloc and core crates failed the build. For some reason (in hindsight, doesn't makes sense now) I thought using 1.49.0 would work better, but there's an LLVM issue with that which prevents it from working properly. So I just tried rust 1.47.0 (and esp-idf 4.2; I re-ran the bindings generation and fixed up differences), but I'm still having one last issue:

error[E0277]: the trait bound `esp32::TIMG0: esp32_hal::timer::TimerGroup` is not satisfied
  --> examples/test.rs:35:23
   |
35 | static TIMER_HANDLER: TimerInterruptHandler<Timer<esp32::TIMG0, esp32_hal::timer::TimerLact>> =
   |                       ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ the trait `esp32_hal::timer::TimerGroup` is not implemented for `esp32::TIMG0`
   | 
  ::: /home/brian/src/esp32-rust/esp32-hal/src/timer/mod.rs:40:24
   |
40 | pub struct Timer<TIMG: TimerGroup, INST: TimerInst> {
   |                        ---------- required by this bound in `esp32_hal::timer::Timer`

I've tried rolling the esp32-hal crate back to mid September of last year, but still hitting this issue. If I go any earlier, I run back into problems with the unstable alloc stuff.

Essentially I'm just trying to figure out what versions of rust and esp32-hal I should be using to be able to successfully compile this. From there I'm happy to work on upgrading to esp-idf 4.2 and getting things like wifi scan results to work, and then eventually see about getting things to work with the latest rust and esp32-hal version.

Thanks for getting started on this project! I'm really excited to be able to build wifi-enabled stuff using rust on esp32!

[Compiling]: inline assembly is unsupported on this target

Hi, ESP-RS team,
I try to compile the project with the installed tooltain.
When I build the project with the command, cargo build -Zbuild-std=core, it generates the error as below:

error[E0472]: inline assembly is unsupported on this target
--> /root/.cargo/registry/src/github.com-1ecc6299db9ec823/xtensa-lx-rt-0.7.0/src/exception/assembly_lx6.rs:1:1

1 | / global_asm!(
2 | | "
3 | | .set XT_STK_PC, 0
4 | | .set XT_STK_PS, 4
... |
70 | | "
71 | | );
| |__^
|
= note: this error originates in the macro global_asm (in Nightly builds, run with -Z macro-backtrace for more info)

Please help have a check and give some hints.

Wi-Fi/BLE bindings to binary blobs, without IDF.

Currently (and most likely always), the WiFi/BLE binaries require a threaded environment to operate.

In this repo (based on the esp32 atm), we use the PRO core as a different thread of execution. This is not feasible long term for a few reasons; it relies on there only ever being one task spawned by the blobs; Most Espressif chips do not have more than one core.

We will need a simple scheduler, there is cortex-m-threads, and even a working example of a similar wifi chip using this approach.

the trait bound `esp32::TIMG0: TimerGroup` is not satisfied

Hi everyone!
I'm trying to build the example but I getting this error:

error[E0277]: the trait bound `esp32::TIMG0: TimerGroup` is not satisfied
  --> examples/test.rs:35:23
   |

   |

   |
40 | pub struct Timer<TIMG: TimerGroup, INST: TimerInst> {
   |                        ---------- required by this bound in `Timer`

Do you have any idea why?
thank-you :)

no `AllocError` in `alloc`

Hey, I really just stumbled upon this and it's quite likely I'm doing something wrong. I tried building the test like this:

cargo espflash --chip esp32 --example test --speed 460800 /dev/ttyUSB0

and I'm getting
