rp-hal VS pico-examples

probably, I didn't really check it, but I found [1]. Rust has a lot of support for embedded systems, even from the companies that provide the chips, like STM and Espressif.

About the same time, I was learning Rust and discovered how it could be used on embedded targets from Low Level Learning on YouTube, the video introduced me to the amazing rp-hal crate that provides abstractions to talk to the Raspberry Pi Pico microcontroller. Getting used to the no_std mode took some time, the most challenging was not being able to collect an iterator to a container.

Well, just as I posted this, I came across the issue on Github: https://github.com/rp-rs/rp-hal/issues/525

Have a read of https://github.com/rp-rs/rp-hal/issues/257 for more info.

I've made an example for a RPI Pico (PR for the RP2040 HAL project here) .

Here's an example: https://github.com/rp-rs/rp-hal/blob/main/boards/rp-pico/examples/pico_usb_twitchy_mouse.rs

What are you on about, can you clarify? Rust can compile in no-std/embedded style just as fine (or better) than C can for basically any ARM or RISCV based processor, and quick googling shows this hal for nearly all pi needs and even MEGA65 is "as supported" (read: not at all officially by anything, fan-only) as any current C compiler. Setting up rust for a new target, so long as the code-gen is supported somehow by LLVM, LLVM plugin, LLVM IR transpiler (and maybe libgcc-jit sort of soon) is just as painful or unpainful as setting up a whole team to work via C/C++ with comparable testing harnesses. This doesn't mean easy and is an area Rust is still improving rapidly by the various enterprise agencies (Ferrous systems, Oxide, more I can't remember...) who specifically want to bring rust to such low end hardware because frankly both C and C++ suck with vendor proprietary tool chains and quirks.

He says he can't find crate for 'bare_metal'. He was setting up and testing the HAL for the pico (https://github.com/rp-rs/rp-hal). While compiling it pulls down critical-section-0.2.7/src/lib.rs and bars on line 7

Navigate to the Pico Examples repository.

I'm experimenting with the "pico/wifi/tcp_server/". It works as expected with a WPA2 secured network, however I can't figure out how to access a WP3 secured network. According to the Pico W datasheet the device supports WPA3. However the function cyw43_arch_wifi_connect_async doesn't seem to have the option to select WPA3. The supported options are CYW43_AUTH_WPA_TKIP_PSK, CYW43_AUTH_WPA2_AES_PSK, or CYW43_AUTH_WPA2_MIXED_PSK.

I connected the MPU6050 and Pico as shown in the wiring guide for the example code here and have also tried using a level shifter with this wiring setup.

There's an iperf opkg pkg, or is it just netperf (which works with fluent)?

Okay I abandoned both of those libraries and tried the simpler WS2812 example in the Pico SDK and I did get it working....finally.

For C++, you could look at the pico-examples on Github https://github.com/raspberrypi/pico-examples

I don't know what you mean. There are dozens of tutorials on the frontpage of google. And just straight up a bt folder of projects for the pico w in the rpi github at https://github.com/raspberrypi/pico-examples/tree/master/pico_w/bt. have you tried that? If you haven't, then you need to work on learning how to use google because people aren't here to do work for you. If you have tried this and it didn't work then reread my previous post and ask better questions.

I'm sorry I don't use the pico-sdk so I'm not 100% sure of which method it'd be. A short lookup in the pico-examples repository brought me to this.

The LED is controlled by a GPIO pin on the radio, not the RP2040. See https://github.com/raspberrypi/pico-examples/blob/master/pico_w/wifi/blink/picow_blink.c.
