<h2>[Unreleased]</h2>
<h2>[v1.0.0-alpha.1] - 2020-06-16</h2>
<p>*** This is an alpha release with breaking changes (sorry) ***</p>
<h3>Added</h3>
<ul>
<li>A nonblocking trait for interfacing with random number generation hardware.</li>
</ul>
<h3>Changed</h3>
<ul>
<li>All traits have been marked as proven (<code>unproven</code> feature has been removed).</li>
<li>All trait methods have been made fallible.</li>
<li>All trait methods have been renamed <code>try_*</code> (i.e. <code>try_send</code>) for consistency.</li>
<li>The <code>Capture</code>, <code>Pwm</code>, <code>PwmPin</code> and <code>Qei</code> traits have been moved into their own
<code>capture</code>, <code>pwm</code> and <code>qei</code> modules for consistency.</li>
<li>Void has been replaced with <code>core::convert::Infallible</code> which should be used
in trait implementations where methods cannot fail.</li>
<li>A new <a href="https://github.com/rust-embedded/embedded-hal#how-to-add-a-new-trait">process</a>
has been adopted for the addition of traits to the embedded-hal.</li>
<li>The minimum supported Rust version is 1.35 due to <a href="https://github-redirect.dependabot.com/rust-lang/rust/issues/54973">this issue</a>.</li>

Continuous Integration

Stabilizer Firmware

Flow diagram

Hardware

Features

  • dual channel
  • SPI ADC
  • SPI DAC
  • 500 kHz rate, timed sampling
  • 2 µs latency, unmatched between channels
  • f32 IIR math
  • generic biquad (second order) IIR filter
  • anti-windup
  • derivative kick avoidance

Limitations/TODOs

  • Fixed AFE gains
  • The IP and MAC address are hardcoded
  • Expose configurable limits
  • 100Base-T only
  • Digital IO, GPIO header, AFE header, EEM header are not handled

Hardware

See https://github.com/sinara-hw/Stabilizer

Minimal bootstrapping documentation

  • Clone or download this
  • Get rustup
  • Get cargo-binutils
  • rustup target add thumbv7em-none-eabihf
  • cargo build --release
  • Do not try the debug (default) mode. It is guaranteed to panic.

Using GDB/OpenOCD

  • Get a recent openocd, a JTAG adapter ("st-link" or some clone) and everything connected and permissions setup. Most Nucleo boards have a detachable ST-Link v2 and are cheap.1
  • Get a multiarch gdb (or a cross arm gdb and edit .cargo/config accordingly)
  • openocd -f stabilizer.cfg and leave it running
  • cargo run --release

Using USB-DFU

  • Install the DFU USB tool (dfu-util)
  • Connect to the Micro USB connector below the RJ45
  • Short JC2/BOOT
  • cargo objcopy --release --bin stabilizer -- -O binary stabilizer.bin or arm-none-eabi-objcopy -O binary target/thumbv7em-none-eabihf/release/stabilizer stabilizer.bin
  • dfu-util -a 0 -s 0x08000000:leave -D stabilizer.bin
  • cargo objcopy --release --bin stabilizer -- -O binary stabilizer.bin or arm-none-eabi-objcopy -O binary target/thumbv7em-none-eabihf/release/stabilizer stabilizer.bin
  • Connect the ST-Link debugger
  • copy stabilizer.bin to the NODE_H743ZI USB disk

Protocol

Stabilizer can be configured via newline-delimited JSON over TCP. It listens on port 1235. stabilizer.py contains a reference implementation of the protocol.


  1. Build a cable: connect a standard 8 conductor ribbon with the wires numbered 1-8 to the pins on the St-Link v2 single row 2.54mm connector as 647513(82) ((i) marks an unused wire) and to the 1.27mm dual row on Stabilizer as 657483x2x1 (x marks an unused pin, enumeration is standard for dual row, as in the schematic). It's just folding the ribbon between wires 5 and 6. The signals on the ribbon are then NRST,TDI,TDO,TCK,TMS,3V3,GND,GND. ↩︎
