Changelog

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

The format is based on Keep a Changelog.

Unreleased

Added

• ws2812: Connect Neopixels to the wristband GPIOs and make your card10 even more colorful!
• micropython.mem_use() function.
• High-pass filter and pulse detection in default ECG app.
• leds.get_rgb(): Get the current color of an LED.
• leds.get_rocket(): Get the current brightness of one of the rockets.

Changed

• Pycardium: Switched from long-long to mpz integer representation. This should resolve any issues with large numbers which had popped up so far.

Fixed

• Backlight and Vibration motor were not reset when switching apps.
• Mismatch in default settings of the Card10 Nickname app.
• Fixed the PMIC ADC muxer not being properly reset to neutral after a measurement.

v1.9 - 2019-08-28 23:23 - IcebergLettuce

Added

• tools/pycard10.py: Tool to interact with card10's serial connection and upload files directly:

  ./tools/pycard10.py path/to/python-script.py

• epic_disp_print_adv & Display.print(font=...): Print with different fonts! The following fonts are supported: 8px, 12px, 16px, 20px, and 24px.
• pycardium: Support for RAW REPL mode.
• bhi160: Function to disable all sensors (bhi160.disable_all_sensors()).
• ls_cmsis_dap: A tool to enumerate CMSIS-DAP debuggers.
• Tons of new features to simple_menu: Timeout, scrolling of long texts, robustness against crashes, and proper exiting.
• card10.cfg config file which allows enabling ELF files.
• Analog read for wristband GPIOs.

Changed

• Refactored menu and personal-state apps.
• main.py was moved into an app to allow easier reconfiguration of the default app. The new main.py points to the "old" one so behavior is not changed.
• After a timeout, the menu will close and main.py will run again.
• BLE security updates.
• More detailed battery state display in nickname app.
• Improved ECG app.

Removed

• Some unused font files.

Fixed

• Fixed a regression which made the ECG app no longer work.
• Fixed card10 advertising support for AT-commands.
• Rectangles being one pixel too small.

v1.8 - 2019-08-27 11:38 - HabaneroChilli

Added

• API-call for direct light-sensor readout: epic_light_sensor_read.
• Pause mode in ECG-App.
• bin field in metatdata for an alternate entrypoint.
• shell.nix: Nix-Shell which installs patched OpenOCD and dependencies.
• Cool LED animation in default ECG app.

Changed

• No longer require locking the display for setting the backlight.

v1.7 - 2019-08-24 21:48 - Garlic

Added

• ESB: Epic Serial Bus (Better than USB!), stability improvements of the USB module. Preparation for mass-storage access in the Firmware.
• Enabled the Hardware Watchdog; Card10 will reset itself if the firmware crashes
• Log messages when BLE is pairing / connected.
• The name of the offending app is printed to the serial console, if an app crashes the metatdata parser.

Changed

• Improved log messages in cases of lock-contention.
• Menu will show an error message if a crash occurs.

Fixed

• Fixed race-conditions in serial writes by using a queue.
• "Card10 Nickname" crashing if only nickname.txt exists.
• Lockup when debug prints are enabled.
• Delayed BHI160 startup a bit so the PMIC task can check the battery first.
• Relaxed the PMIC lock-timeouts so other task can take a little more time.
• Fixed off-by-one error in gfx_line().
• Fixed the API interrupts sometimes getting stuck.
• Fixed binary building on MacOS.
• Fixed race-conditions in serial console prints by introducing a queue.
• Fixed API & MAX30001 mutexes being initialized late sometimes.
• Fixed wrong stripe width in bi flag.

v1.6 - 2019-08-23 20:30 - Fennel

• Maxim BLE SDK update

Added

• BLE: Added personal state API to card10 SVC.
• ECG: Support for ECG + Python app
• BLE: Characteristic to read the time

Changed

• Improved performance of circle-drawing algorithm.

Fixed

• Removed a debug print in the bhi160 module.

v1.5 - 2019-08-23 00:18 - Eggppppplant

Added

• bootloader: Add an error message when flashing fails.
• display: Option to set backlight from Python
• utime: Function to read time in ms from Python

Changed

• gpio: Rename constants for consistency.
• ble: Storing pairings outside BLE stack context
• security: Disable ELFs by default, prevent access to some more files

Fixed

• gpio: Fix field-setting in gpio_cfg_t.

v1.4 - 2019-08-22 19:43 - DaikonRadish

Added

• Support for the bme680 environmental sensor.
• Support for the bhi160 sensor fusion.
• simple_menu module for creating simple menus in Python.
• power module to access the voltage and current measurements from the PMIC.
• Support for color themes in the default clock script: Color themes are read from a json file, so people can customize their clock. Last selected theme is saved in the clock.json so it is persistent.

Changed

• Refactored BLE card10 service.
• Improved BLE file-transfer (added security).
• Replaced dynamic attribute creation with static attributes.

Fixed

• Fixed menu listing files starting with ..
• Fixed utime.set_time() applying the timezone offset in the wrong direction.
• Fixed the PMIC driver not releasing some locks properly.

v1.3 - 2019-08-22 00:12 - CCCauliflower

Added

• A splashscreen in Epicardium showing the version number.
• os.urandom() function.

Changed

• BLE file-transfers now create missing folders.

Fixed

• gfx: Add a linebreak before character, not after. This prevent the last character being cut off.
• Fixed serial task overflowing because it had a too small stack size.
• Removed confusing MAXUSB messages.
