In a sister project we have introduced the YLab for building interactive sensor recording devices. Using CircuitPython, developing sensors for everyday research never was easier.
The purpose of YLab Edge is to follow YLab in spirit, but improve on what Ylab lacks the most, and that is: speed! Highest achieved readings with YLab are in the range of 250 SPS, which is enough for many applications, but is insufficient for large sensor arrays with high sample rates, e.g. motion capture or EEG. The solution is to re-implement the YLab API in the systems programming language Rust.
YLab Edge Pro is the version to use for STM32 microcontrollers. Currently, Pro is also the most powerful version in terms of channels and throughput. However, it is not interactive, like YLab Edge Go.
Currenty, the following devices are implemented using [Embassy]: https://embassy.dev/. All devices are running in their own async task.
- LED control
- on-board ADC channels
- USART data transfer
A test system with
- 16 analog channels in two banks @ 600 Hz
All code in this crate is currently developed for STM Nucleo devices with an F446 MCU. This is branch Nucleo64, using the Nucleo-64 board with an F446RE MCU.
To install the latest version of YLab Edge Pro:
- Install Rust and Cargo on your system
- clone this repository (e.g. in VSC)
- run cargo update
- connect an STM32 Nucleo board via USB
- open a terminal in the ylab-edge folder and type:
$ cargo run --bin ylab_dgIf you get an error about not being able to find probe-rs, try:
$ cargo install probe-rsthen try repeating the cargo run command above.
