f0.97.1

Touch sensitivity tune shortcut

• Touch sensitivity tune LED patterns changed to match the updated manual.

f0.97.0

Touch sensor

• Measurements and threshold use float values (decimals).
• Multiple samples taken and averaged, until using all the time budget (100 microseconds).
• Option to toggle measurement polarity.
• Default measurement polarity is inverted.
• Debounce prioritizes keeping the touch detection up to avoid microcuts.
• New automatic threshold logic based on baseline factor.
• Changed touch sensitivity presets:
  • Preset 1: Auto low.
  • Preset 2: Auto mid (default).
  • Preset 3: Auto high.
  • Preset 4: Custom 1.
  • Preset 5: Custom 2.

Calibration / Drift

• Option to perform long calibration (4x longer).
• Option to swap gyros (left <-> right).
• Fix for calibration procedure getting wrong values under some circumstances.
• Fix for LED cycling animation not being smooth.
• Added user calibration offsets (see Ctrl app 0.97.0 release for more info).

Log modes

• Log mask to enable additional logs on demand.

Home button fixes

• Fix for home profile (shortcuts) getting stuck under some circumstances.
• Fix for home button double-press + hold not holding the gamepad guide button (required for Steam Deck shortcuts).

NVM (Non Volatile Memory)

• Reserved space for all the new features in the config struct.
• Config sector version 97000 (Controller config will reset to factory defaults if version does not match).

f0.96.0

Buttons

• Added double-press mode.
  • Double-press time is defined in config value CFG_DOUBLE_PRESS_TIME, which is 300 milliseconds by default.
• Button OVERLAP has been renamed to IMMEDIATE. (Since outputs do not overlap when applied to double-press).
• Button modes are now bitmask flags (NORMAL, HOLD, DOUBLE, IMMEDIATE, LONG, STICKY) and can be combined in the profile definitions. Though not all permutations are supported. See button_logic.md

Profiles

• Unlocked 4 slots for custom profiles, default names are Custom 1, Custom 2, Custom 3, Custom 4.
• Custom profiles are selected by holding Home + double-pressing a D-pad direction.
• Custom profiles are indicated on the controller LEDs with 2-on 2-off patern:
  

WebUSB

• Profile overwrite feature:
  • Ctrl app can request profile slots to be overwritten with build-in defaults.
  • Ctrl app can request profile slots to be overwritten with a profile from other slot.
• Profile SECTION_SET request over WebUSB now replies with an async confirmation, so the Ctrl app can send batches of profile data (profile loading from file).
• Controller firmware version is shared with the Ctrl app.
• Ctrl app shares the system time with the controller (for latency measurements).

Thumbstick

• Added anti-deadzone feature.
  • Anti-deadzone value is contained in each profile thumbstick settings. (There is no global anti-deadzone value).
  • Anti-deadzone is applied after deadzone, so the defined deadzone remains as a zero-output area.

Gyro

• Gyro ALWAYS_ON mode not working as expected has been fixed.

NVM (Non Volatile Memory)

• Each profile in flash memory is labeled with its own version identifier.
• Config and profile(s) sectors can be reset individually.
• Config sector version 96000 (Controller config will reset to factory defaults if version does not match).
• Profile(s) sector version 96000 (Profile slot will reset to factory defaults if version does not match).

f0.95.0

Communication

• Mouse delta values (X, Y) are now 16 bits, so they do not saturate even when using very high sensitivity.
• Device identifier for Windows XInput mode changed to A09C.
• Device identifier for Generic HID / DirectInput mode changed to A09D.

Profiles

• Double-click home shortcuts (enabled when double-clicking and holding home) now activates default gamepad buttons, even if the Console Legacy profile was modified.

Automatic diagnostics.

• During the booting sequence, the controller will automatically detect if there are issues such as:
  • Lack of calibration.
  • Problems when initializing the gyro(s).
• The controller LEDs display a blinking warning pattern if problems are detected.
• The users can dismiss the LED warning (until next boot) by double-clicking home.
• If the problem is unclear, the user can check the logs in the Ctrl app for more details.

NVM (Non Volatile Memory)

• Config memory block version 16 (Controller will reset to factory defaults if version does not match).

f0.94.0

Profiles

• Profiles are stored in the controller NVM in low-level Ctrl protocol format.
• Profile data can be read and writen via WebUSB (from/to the Ctrl app).
• If no profiles are stored, they are loaded from defaults.
• Default profiles (in code) now use Ctrl protocol format.
• Action labels included in profiles as strings (eg: Jump).

Thumbstick

• Thumbstick is disabled if the controller was never calibrated, this makes more obvious that the controller must be calibrated, and avoids unexpected input being sent.
• Fixed a bug in which deadzone applied to button mappings (eg: WASD) was incorrectly calculated.
• Default deadzone preset values changed to 8%, 12% and 20%.
• Default saturation has been reduced a bit, so outer deadzone is smaller.
• Radial mode refactored as distance calculation modes (axial or radial).

Touch

• Fixed touch sensitivity values from Ctrl app being always overwritten with defaults.
• Fixed touch sensitivity preset sorting reversed (changed back to the intended sorting introduced in f0.90.0).

Macros

• Now each profile has 8 macro slots, and they are triggered via procedure mapping (eg: PROC_MACRO_1).

NVM (Non Volatile Memory)

• Implemented cache in front of in-memory config and profiles, so read and writes from/to flash memory are reduced a lot.
• Each profile is allocated 4096 bytes of memory.
• Config memory block version 15 (Controller will reset to factory defaults if version does not match).

f0.93.0

Config

• Mouse sensitivity, touch sensitivity and deadzone preset values are stored in the controller memory.
• Preset values can be read and modified from WebUSB (Ctrl app).
• Default preset values are initialized with the same values that used to be hardcoded:
  • Mouse sensitivity: 1x, 1.5x, 2x.
  • Thumbstick deadzone: 7%, 10%, 15%.
  • Touch sensitivity:
    • Old PCBs: Auto, 2μs, 3μs, 5μs, 8μs.
    • New PCBs: Auto, 10μs, 15μs, 25μs, 40μs.

NVM

• Config memory block version 12.
• This update may reset the controller config to default values (Windows mode, no calibration, etc).
