Fixes #1744 Set the terminal tilegrid NULL after free 2019-04-03T22:24:15+00:00 Scott Shawcroft scott@tannewt.org 2019-04-03T22:24:15+00:00 urn:sha1:a5520f8a3d7d866d4e97de8f04a08ab3dd908470 Without this, a double free can occur when a display (and terminal) is released and then a crash occurs. Upon a second release, different memory is released (sometimes the heap). When this is followed by an allocation for the flash cache, the cache can overwrite the active heap causing crashes. Fixes #1667 Store the original layer in Group 2019-02-15T22:29:59+00:00 Scott Shawcroft scott@tannewt.org 2019-02-15T22:29:59+00:00 urn:sha1:c9f036ed405f8e5ddf34dd2e15ad4074a270c3c4 As is we would return the native superclass object only. Fixes #1551 A variety of displayio improvements 2019-02-12T04:55:05+00:00 Scott Shawcroft scott@tannewt.org 2019-02-06T20:13:17+00:00 urn:sha1:c17f147be95e7490e5207c747add2da1cc8b167f This changes a number of things in displayio: * Introduces BuiltinFont and Glyph so the built in font can be used by libraries. For boards with a font it is available as board.TERMINAL_FONT. Fixes #1172 * Remove _load_row from Bitmap in favor of bitmap[] access. Index can be x/y tuple or overall index. Fixes #1191 * Add width and height properties to Bitmap. * Add insert and [] access to Group. Fixes #1518 * Add index param to pop on Group. * Terminal no longer takes unicode character info. It takes a BuiltinFont instead. * Fix Terminal's handling of [###D vt100 commands used when up arrowing into repl history. * Add x and y positions to Group plus scale as well. * Add bitmap accessor for BuiltinFont Fix built-in inits and terminal allocate 2019-02-01T09:00:10+00:00 Scott Shawcroft scott@tannewt.org 2019-02-01T09:00:10+00:00 urn:sha1:03068a93884e5d0c7bd5b937e0362b379bb2ac9a Fix hallowing and nrf builds 2019-01-31T19:42:15+00:00 Scott Shawcroft scott@tannewt.org 2019-01-30T01:10:17+00:00 urn:sha1:ec0388704095a7d3ab0cda65509db2fa0ef589dc Remove Sprite references 2019-01-31T19:42:14+00:00 Scott Shawcroft scott@tannewt.org 2019-01-29T23:40:20+00:00 urn:sha1:4672866eecebffed383b7882db13c71d3495d846 More improvements to Terminal: 2019-01-31T19:42:14+00:00 Scott Shawcroft scott@tannewt.org 2019-01-29T23:04:07+00:00 urn:sha1:601a910f4eb83cf1ae7516a25c011b469ac76b8b * Fix Hallowing. * Fix builds without displayio. * Fix y bounds that appears as untrollable row of pixels. * Add scrolling to TileGrid. * Remove Sprite to save space. TileGrid is a drop in replacement. Hook up the terminal based on the first display. 2019-01-31T19:42:14+00:00 Scott Shawcroft scott@tannewt.org 2019-01-26T00:59:18+00:00 urn:sha1:1a1dbef992442682413f6103e36440a26bc2dad7
