Questions regarding CH582F chip #2

happytm · 2023-12-28T20:34:09Z

I am new to rust language. I have some questions regarding using CH582F chip.

I want to make an IOT project where I want to read 3 ADC pins every 5 minutes to read temperature, light level and battery level and then broadcast it using BLE (preferably coded phy 125kb for longer range). After broadcasting the chip should go to sleep for 5 minutes to conserve battery power.

Is this possible with current code in your repository?

Thanks.

read 3 ADC pins every 5 minutes to read temperature, light level and battery level

ADC and RTC part works as expected.

then broadcast it using BLE (preferably coded phy 125kb for longer range).

The BLE broadcaster example also works.

After broadcasting the chip should go to sleep for 5 minutes to conserve battery power

I haven't looked into lower power sleep. The current implementation uses WFI opcode and DCDC. I need to check the official EVT for a full low power implementation

Happy new year.

Sorry to bother you again. My goal is to flash board linked below using USB interface:

https://github.com/WeActStudio/WeActStudio.WCH-BLE-Core

I am trying to compile on Windows 7 machine but I am getting following errors:

Is there something I am missing in setting up rust environment?

Please help me get started.
Thank you.

Check out rust-lang/rust#44787 (comment)
It seems mingw32's version is buggy while linking against some rust libs.
The MSVC toolchains might work.

@andelf I searched on google for silutions for whole day but was unsuccessful.

Finally I removed all old installation of rust and installed standalone rust application which can compile hello world example created by typing "cargo new hello".

But when I try to compile your repository it gives following errors:

Please help.
Thanks.

I tried "hello world and seems like rust setup works fine.

@andelf Unfortunately, with rust standalone I dont have rustup available.

Is there any manual setting where I can add target?

Thanks.

This is the installation I have:


The official Rust standalone installers contain a single release of Rust, and are suitable for offline installation. They come in three forms: tarballs (extension .tar.gz), that work in any Unix-like environment, Windows installers (.msi), and Mac installers (.pkg). These installers come with rustc, cargo, rustdoc, the standard library, and the standard documentation, 
but do not provide access to additional cross-targets like rustup does.

The most common reasons to use these are:

Offline installation
Prefering a more platform-integrated, graphical installer on Windows
Each of these binaries is signed with the [Rust signing key](https://static.rust-lang.org/rust-key.gpg.ascii), which is [available on keybase.io](https://keybase.io/rust), by the Rust build infrastructure, with [GPG](https://gnupg.org/). In the tables below, the .asc files are the signatures.

That's a common error, use rustup default nightly to use the nightly release.

happytm · 2024-01-01T07:45:46Z

Finally. It compiled with some warnings.

Thank you so much for your help.

Now how can I download compiled Hex file using USB interface to above mentioned development board?

andelf · 2024-01-01T13:51:54Z

Use either of https://github.com/ch32-rs/wchisp and https://github.com/ch32-rs/wlink

happytm · 2024-01-01T18:14:06Z

@andelf I will take a look.

Thanks.

happytm · 2024-01-02T17:44:43Z

@andelf Pardon my ignorance. I was able to compile "brodcaster" example with your help.

I have WeActstudio ch582f board with built in USB port.
I need to flash the compiled "broadcaster" code from my windows 7 machine to this board but do not know how to do it.

I have installed official WCHISP tool on my computer. Usually , With Mounriver studio it creates *.hex file and I download this *.hex file using USB port on my board and WCHISP tool.

Can you give me step by step instructions please?

Thanks.

andelf · 2024-01-03T06:50:29Z

I have a WeActStudio CH582F too. It's the primary board I used to develop ch58x-hal. 😄

You need to locate the objcopy tool to convert ELF to bin or ihex(.hex) files.
You can use the objcopy bundled with Rust's llvm-tools.

> rustup component add llvm-tools
Then you will have `cargo objcopy` available

> cargo objcopy --release --example blinky -- -O binary blinky.bin
This generates the binary firmware

> cargo objcopy --release --example blinky -- -O ihex blinky.hex
This generates the .hex file for WCHISPTool

happytm · 2024-01-03T07:06:10Z

@andelf Thank you. I get following message:

Try this:

$ cargo install cargo-binutils

$ rustup component add llvm-tools

https://github.com/rust-embedded/cargo-binutils

happytm · 2024-01-03T07:33:30Z

@andelf It did a trick. I got blinky.hex file.

Thank you so much for helping me setup end to end environment for Rust embedded.

Now is time to play with all your great code for this amazing little chip . I will sleep better. Goodnight.

happytm · 2024-01-03T19:19:51Z

@andelf

I will leave this instructions here for future user of this repository using windows 7 machine:


 1. Download Rust installer from here https://rustup.rs/
 2. Use option 2 and enter default host triple as "x86_64-pc-windows-gnu" and use enter key for all other options.
 3. Now use option 1 to proceed with installation(default). This will use default host triple "x86_64-pc-windows-gnu".
 4. Now use following 3 commands in project root directory:
          cargo install cargo-binutils
          rustup component add llvm-tools
          cargo objcopy --release --example blinky -- -O ihex blinky.hex

 5. Use official WCHISP tool from WCH to flash *.hex file. Tool can be downloaded from here https://www.wch-ic.com/downloads/WCHISPTool_Setup_exe.html
