Change Log

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

v0.10.0

Added

  • Serial terminal is available on USB for settings configurations
  • Reboot to DFU support added via the serial terminal for remote bootloading
  • The meta topic now contains metadata about the compiler, firmware, and hardware similar to Booster
  • Panic information is now persisted after reboot and available via telemetry and the USB serial console.
  • Device operational settings can now be modified, stored and cleared from device flash using the USB serial console. Run-time settings are unique to each application, but network settings are unified for all applications (i.e. lockin, dual-iir, etc.)

Changed

  • Broker and static IP/DHCP are no longer configured at compile time, but is maintained in device flash and can be changed via the USB port.
  • MSRV removed. Stabilizer uses latest stable rust.
  • The IIR (biquad) filter used for PID action has changed its serialization format. See also the iir_coefficients Python CLI implementation.
  • The stream target is now configures as a 1.2.3.4:4321 string

Fixed

  • Fixed an issue where the device would sometimes not enumerate on Windows

v0.9.0

Fixed

  • Fixed a defect where powering up with Pounder attached would cause an internal panic.

Changed

  • idsp crate update to 0.10: lockin now uses a double second order lowpass.
  • The batch_size field in the the UDP stream frame now contains the number of batches not the number of samples per batch. It has been renamed to batches.
  • All MQTT clients upgraded and APIs updated.
  • MQTT broker may now be specified via DNS hostnames
  • hitl/streaming.py no longer requires a prefix
  • Streaming now supports UDP multicast addresses

v0.8.1 - 2022-11-14

  • Fixed the python package dependencies

v0.8.0 - 2022-11-07

  • [breaking] MSRV bumped to 1.63 (array_from_fn via enum_iterator)
  • [breaking] Bumped dependencies on miniconf, minimq leading to changes in the Miniconf settings API
  • Bumped HAL dependency to fix a crucial I2C bug
  • Added gain limits for iir_coefficients
  • Added a IIR transfer function plotting tool
  • Fixed a bug in the Python telemetry client that led to no data being returned
  • EEM Gpio pins are now available from setup()
  • Added white noise output to signal_generator

v0.7.0 - 2022-08-10

Added

  • Optional specification of a static IP address (#509)
  • Temperature sensor measurement for Pounder and Stabilizer's CPU has been added #575
  • External clock support for Pounder
  • Auxiliary ADC support for Pounder

Removed

  • Minimum supported Rust version bumped to 1.62
  • The pounder_v1_1 feature has been replaced by the pounder_v1_0 feature with inverse meaning.
  • The Telemetry python client has been integrated into the stabilizer Python library

Fixed

  • Fixed panics when using a batch size of 1 (#540)
  • Fixed an issue where startup delays were 1/4 of what they should be (#524)
  • Fixed Pounder GPIO extender issues by rewriting the mcp280xx crate
  • Fixed improper calculation of the signal generator phase increment (#543)

v0.6.0 - 2022-02-11

Added

  • Telemetry (#341)
  • Logging via RTT (real time tracing) over SWD/JTAG instead of semihosting for fast and low-overhead debugging (#393 #391 #358)
  • Settings structures now automatically publish after a short delay on boot (#475)
  • Full-rate data streaming (e.g. complete raw ADC/DAC data) via Ethernet/UDP (#414 #394 #380)
  • Compilation specifically targeting Cortex-M7 instruction set for faster code (#358)
  • Fast double-buffered DMA pattern for less overhead (#367)
  • Integrated signal generator for stimulus and scan waveform generation (#434 #388)
  • Expanded code documentation (#452 #346)
  • Quick-start guide and book (#431 #430 #401 #404 #483)
  • Expanded and revised python API including the computation of IIR coefficients from PID gains (#472 #471 #451 #427)
  • Device MQTT broker connection status indicated via MQTT (#468 #441)
  • The signal generator supports adjusting its phase (#505)

Changed
