Scott Shawcroft	f21cf15c38	Add OnDiskBitmap which loads pixel data straight from disk. ... Also, renamed Sprite's palette to pixel_shader so it can be anything that produces colors based on values (including color values). Added a ColorConverter that converts RGB888 (found in bitmaps) to RGB565 for the display. Fixes #1182	2018-09-12 15:25:59 -07:00

Scott Shawcroft	6697544cdf	Introduce displayio to render graphics to displays. ... It's designed to minimize RAM footprint by using Sprites to represent objects on the screen. The object model also facilitates partial screen updating which reduces the bandwidth needed to display. This is all handled in C. Python simply manipulates the objects with the ability to synchronize to frame timing.	2018-08-31 12:31:52 -07:00

Scott Shawcroft	de5a9d72dc	Compress all translated strings with Huffman coding. ... This saves code space in builds which use link-time optimization. The optimization drops the untranslated strings and replaces them with a compressed_string_t struct. It can then be decompressed to a c string. Builds without LTO work as well but include both untranslated strings and compressed strings. This work could be expanded to include QSTRs and loaded strings if a compress method is added to C. Its tracked in #531.	2018-08-16 17:40:57 -07:00

Jeff Epler	b0e33f6a11	atmel-samd: UART: allocate rx buffer in long-lived region ... This is not strictly needed in order for #1056 to be resolved, because the "make long-lived" machinery is unaware of this pointer. However, as UARTs are assumed to be long-lived, this change is beneficial because it moves the long-lived buffer into the upper memory area with other long-lived objects, instead of remaining in the low heap.	2018-08-08 19:21:57 -05:00

Noralf Trønnes	e158702a68	atmel-samd/samd51: Use crystal for RTC ... This uses the crystal to clock the RTC on boards which have a crystal. Disable clock generator 2 which was enabled in commit 8e2080411f ("atmel-samd: Add rtc module support"). samd51 differs from samd21 when it comes to the RTC clock. samd51 doesn't have an explicit clock peripheral so no need for a clock generator. The same commit didn't even setup XOSC32K correctly, it missed EN1K and XTALEN. The RTC uses the 1k clock output, so enable it on the OSCULP32K even if it works without it.	2018-06-01 18:03:23 +02:00
Noralf Trønnes	ab7ddfddd5	atmel-samd/samd51: Refactor clock setup ... Refactor the convoluted asf4 clock setup into something more readable. enable_clock_generator() has 2 changes: - Set 'Output enabled' to match the current clock setup - Handle divisors above 511 Add an enable_clock_generator_sync() version which makes it possible to setup clocks without waiting for syncing. The bootup would hang without this.

Scott Shawcroft	4140b3b944	atmel-samd: Stop double CSW after MSC reads ... This explicit zero length xfer leads to a second CSW packet. If another read was started between the two CSWs then the host gets confused and resets the device. On reads, the CSW is automatically sent when we reply with the total length. Writes must do it manually so they can wait for the disk to flush the data.	2017-11-03 15:08:55 -07:00

Scott Shawcroft	268bf6f99e	atmel-samd: Fix non-DEBUG USB cdc. ... I believe the issue was that LTO exacerbates a problem where a CDC read is initiated but fails and leaves pending_read true preventing further reads.	2017-10-31 15:43:45 -07:00
