simple_frame_app 3.0.0

Flutter and Lua quickstart app scaffolding and standard library functions for Brilliant Frame development on Android/iOS

3.0.0

• Changed RxPhoto to rotate back to upright by default. Specify upright: false in the constructor to save a few cycles if you don't need it

2.0.3

• Changed default invalid plain_text color VOID/0, changed to WHITE/1

2.0.2

• Removed unusable quality 100 from camera settings drawer

2.0.1

• Changed camera_capture_and_send() to remove all delays between sends on Frameside, just retry on bluetooth send failure. Overall performance improvement, but retry counts of 10, 50, 100+ occur with some packets suggesting further improvement is possible.

2.0.0

• Renamed printInstructions(), tapHandler() to standardized names of onRun(), onTap(), and added onCancel() abstract function to allow implementing app class to perform app-specific initialization and cleanup

1.8.0

• Added frame_vision_app mixin as a specialized form of simple_frame_app for computer vision applications. Separate templates are now provided in templates/ for simple_frame_app and frame_vision_app apps. Frame Vision Apps automatically listen for taps which can be used to capture photos, and provide a hook for a vision processing pipeline when photos are captured. Auto and Manual exposure camera settings are supported and a settings drawer widget is provided.

1.7.0

• Fixed scan/connect/reconnect code to be able to be called synchronously, and properly awaited.
• Added helper startup method to try scanning, connecting, starting Frame app and optionally running phoneside run() method, suitable for use in some apps from initState()

1.6.1

• Fixed bitmask bug causing analog_gain_limit and manual_analog_gain to be incorrectly parsed in Lua

1.6.0

• Added rudimentary support for TxSprite.fromImageBytes() to load arbitrary PNG or JPG files for display on Frame (previously limited to indexed PNG files of 2, 4, or 16 colors only)

1.5.1

• Corrected 'GRAY' to 'GRAY' for plain_text display to match firmware

1.5.0

• Added simple moving average smoothing option for IMU data

1.4.1

• Tweaked Lua source file for image_sprite_block to prevent a bug introduced by the minifier stripping out necessary parentheses

1.4.0

• Added RxIMU parser and corresponding frameside sender for streaming magnetometer (compass) and accelerometer data from Frame

1.3.0

• Added TxImageSpriteBlock for splitting an image into lines of TxSprite, allowing for progressive/incremental rendering. Also supports in-place updates of sprite lines for continuously updating images.

1.2.0

• Updated TxCameraSettings and camera.lua to support both autoexposure and manual exposure/gain photos

1.1.1

• removed extra logging statements in text_sprite_block.lua

1.1.0

• implemented TxTextSpriteBlock more fully to support multi-line text, including scrolling frameside when the number of lines sent exceeds maxDisplayRows. The call to rasterize() has been updated to require providing indices for lines to rasterize.

1.0.1

• fixed TextUtils to change wrapTextSplit to wrapText, i.e. wrapText now returns List<String>, so join('\n') the result if a single string is required

1.0.0

• removed deprecated *DataResponse functions, use Rx classes instead (RxAudio, RxPhoto, RxTap)

0.1.0

• Added Rx classes in place of imageDataResponse, audioDataResponse, tapDataResponse.
• Deprecated TextUtils.wrapText(Split), going forward use the wrapText that returns a List of Strings and join them if you need the single String

0.0.9

• Added audioDataStreamResponse support for real-time streaming of Frame audio data
• Added tapDataReponse as a multi-tap-detection subscription from Frame
• Added wrapTextSplit and deprecated wrapText in TextUtils, returning a List<String> instead of a String so the caller to quickly select the first, last or a sliding window of Strings to enable scrolling. If a newline-joined single String is desired, it can quickly be assembled with a join()
• Performance: modified logging calls with expensive string interpolations to use a closure so they are not evaluated if not logged at the current logging level

0.0.8

• Added initial audioDataResponse support for Frame audio data as whole audio clips

0.0.7

• Updated camera code (lua and dart) with camera parameters from recent firmware updates - exposure_speed, analog_gain_limit, white_balance_speed etc.

0.0.6

• Added TxTextSpriteBlock message type to send a paragraph of text for display on Frame. Supports Unicode (including right-to-left) script. Rasterization is performed phoneside and text is sent as a series of TxSprites
• Renamed tx/text.dart and lua/text.lua to plain_text to match class names - no interface change, just update imports/assets

0.0.1

• Early prototypes
