2020-09-21_canio: Minimal implementation for SAM E5x MCUsJeff Epler
Tested & working: * Send standard packets * Receive standard packets (1 FIFO, no filter) Interoperation between SAM E54 Xplained running this tree and MicroPython running on STM32F405 Feather with an external transceiver was also tested. Many other aspects of a full implementation are not yet present, such as error detection and recovery.

Fix RGBMatrix, FrameBufferDisplay bugs
2020-09-02rgbmatrix: Move struct definition to shared-module, rename 'core' memberJeff Epler
2020-09-01RGBMatrix: Remove unused, dead allocationJeff Epler
@tannewt noticed this in a pull request review. The allocated memory was never used, but the GC would have collected it eventually.
2020-09-01FramebufferDisplay: Don't set rotation via core_constructJeff Epler
The expectations of displayio.Display and frambufferio.FramebufferDisplay are different when it comes to rotation. In displayio.Display, if you call core_construct with a WxH = 64x32 and rotation=90, you get something that is 32 pixels wide and 64 pixels tall in the LCD's coordinate system. This is fine, as the existing definitions were written to work like this. With framebuffer displays, however, the underlying framebuffer (such as RGBMatrix) says "I am WxH pixels wide in my coordinate system" and the constructor is given a rotation; when the rotation indicates a transpose that means "exchange rows and columns, so that to the Groups displayed on it, there is an effectively HxW pixel region for use". Happily, we already have a set_rotation method. Thus (modulo the time spent debugging things anyway:) the fix is simple: Always request no rotation from core_construct, then immediately fix up the rotation to match what was requested. Testing performed: 32x16 RGBMatrix on Metro M4 Express (but using the Airlift firmware, as this is the configuration the error was reported on): * initially construct display at 0, 90, 180, 270 degrees * later change angle to 0, 90, 180, 270 degrees * no garbled display * no safe mode crashes
2020-09-01rgbmatrix: Disable timer while reconstructing the displayJeff Epler
2020-09-01allocator.h: add a missing license noticeJeff Epler
2020-09-01rgbmatrix: Don't inline the allocator functionsJeff Epler
2020-09-01rgbmatrix: recover gracefully from allocation errorsJeff Epler
e.g., allocating a 192x32x6bpp matrix would be enough to trigger this reliably on a Metro M4 Express using the "memory hogging" layout. Allocating 64x32x6bpp could trigger it, but somewhat unreliably. There are several things going on here: * we make the failing call with interrupts off * we were throwing an exception with interrupts off * protomatter failed badly in _PM_free when it was partially-initialized Incorporate the fix from protomatter, switch to a non-throwing malloc variant, and ensure that interrupts get turned back on. This decreases the quality of the MemoryError (it cannot report the size of the failed allocation) but allows CircuitPython to survive, rather than faulting.
