Stabilizer Firmware

Hardware

Hardware

Applications

The Stabilizer firmware offeres a library of hardware and software functionality exposing input/output, timing, and digital signal processing features. An application can compose and configure these hardware and software components to implement different use cases. Several applications are provides by default

Dual-IIR

Flow diagram

  • dual channel
  • SPI ADC
  • SPI DAC
  • up to 800 kHz rate, timed sampling
  • down to 2 µs latency
  • f32 IIR math
  • generic biquad (second order) IIR filter
  • anti-windup
  • derivative kick avoidance

Lockin external

Lockin internal

Minimal bootstrapping documentation

  • Clone or download this
  • Get rustup
  • rustup target add thumbv7em-none-eabihf
  • cargo build --release
  • When using debug (non --release) mode, increase the sample interval significantly. The added error checking code and missing optimizations may lead to the code missing deadlines and panicing.

Using Cargo-embed

  • Install cargo-embed: cargo install cargo-embed
  • Program the device: cargo embed --bin dual-iir --release

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.[^swd]
  • 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
  • Get cargo-binutils
  • cargo objcopy --release --bin dual-iir -- -O binary dual-iir.bin or arm-none-eabi-objcopy -O binary target/thumbv7em-none-eabihf/release/dual-iir dual-iir.bin
  • dfu-util -a 0 -s 0x08000000:leave -D dual-iir.bin

Using ST-Link virtual mass storage

  • Get cargo-binutils
  • cargo objcopy --release --bin dual-iir -- -O binary dual-iir.bin or arm-none-eabi-objcopy -O binary target/thumbv7em-none-eabihf/release/dual-iir dual-iir.bin
  • Connect the ST-Link debugger
  • copy dual-iir.bin to the NODE_H743ZI USB disk

Protocol

Stabilizer can be configured via MQTT. Refer to miniconf for more information about topics. A basic command line interface is available in miniconf.py.
