acc4fe4d7d atmel-samd: Stop relying on an external crystal. 2016-11-07 12:37:38 -08:00
Scott Shawcroft
23112a6434 atmel-samd: Merge init into the constructor and check all available 
SERCOMs during initialization.

Fixes #16. It was broken because the MISO pin used the second SERCOM.
 2016-11-01 17:30:01 -07:00
Scott Shawcroft
674f3d46e8 atmel-samd: Reset all SERCOMs except the SPI flash one if used. #29 2016-11-01 11:03:12 -07:00
Scott Shawcroft
19e5f1fef2 atmel-samd: Break out of delays with CTRL-C. 
This means you can CTRL from within time.sleep() and that autoreset
will work from within a long sleep too. Fixes #45.
 2016-10-31 11:31:52 -07:00
Scott Shawcroft
f42b41e1e9 atmel-samd: Increase autoreset delay to reduce duplicate resets. 2016-10-31 11:31:33 -07:00
Scott Shawcroft
5b3a143ffe atmel-samd: Rework tick timer to use TC5 and support neopixel status LED. 
The tick timer needed to be reworked because the ASF delay functions also
use the SysTick timer. Now, it uses TC5 and calls out to the autoreset
logic every tick. Fixes #43.

Added neopixel status colors and corrected the latch time from ms to us.
Fixes #42.

fc78f6950f atmel-samd: Add D13 as flash write indicator on Arduino Zero. 2016-10-27 17:49:52 -07:00
Scott Shawcroft
86a1d1db30 atmel-samd: Fix autoreset when no repl is present and keep running mss storage code during a sleep. 2016-10-27 17:48:42 -07:00
Scott Shawcroft
3a9cb1ac49 atmel-samd: Fix Arduino SPI pin. Datasheet net name is wrong. :-( 2016-10-26 20:16:53 -07:00
Scott Shawcroft
85e4d3572d atmel-samd: Add named pins for Arduino Zero SPI. Fixes #11. 2016-10-26 18:02:34 -07:00
Scott Shawcroft
2098515f6a atmel-samd: Rework pin definitions to share most of the data structures and included based on ASF defines. 2016-10-26 17:57:47 -07:00
Scott Shawcroft
73848f4cd0 atmel-samd: Stop aliasing os to uos and time to utime. They expose different APIs. Fixes #23. 2016-10-26 13:33:50 -07:00
Scott Shawcroft
34fa81eaf3 atmel-samd: Hook in DTR for more ports and make the serial TX more resiliant to long strings. 2016-10-26 13:32:41 -07:00
Scott Shawcroft
d189a3f3cf atmel-samd: Support auto-reset based on USB write activity. 
It will soft-reboot micropython after a burst of writes to the
file system. This means that after you save files on your computer
they will be automatically rerun.

This can be disabled in the build by unsetting AUTORESET_TIMER in
mpconfigboard.h.

Using the REPL will also prevent the soft resets until you reset
with CTRL-D manually.
 2016-10-25 18:36:37 -07:00
Scott Shawcroft
614c1fdba2 atmel-samd: Only output to USB after DTR and don't send anything larger than the room left in the USB TX buffer. 2016-10-25 18:29:04 -07:00
Scott Shawcroft
b7768a74a7 atmel-samd: Fix file system init. 
Adding the USB write protection prevented file system reset from
working. Since it happens before USB start we temporarily set the
volume to writeable and then set it back to read-only before USB is
started.

Scott Shawcroft
98c8f2f6a3 atmel-samd: Update the FatFs sector cache on USB mass storage write 
to the same sector.

This fixes #20, the issue where a listdir or import won't work
without a reset when it was run before the file was copied.
 2016-10-21 15:44:10 -07:00

b8ef783052 extmod: Fix getting sector size when the max and min sizes are the 
same.

Also switch the max size back to 512 for atmel-samd to save ram.
 2016-10-21 15:44:10 -07:00
Scott Shawcroft
9eb86e8015 Add support for USB writeable, MicroPython read-only volumes. 
This prevents file system corruption due to two systems mutating
it at once.

8b1526e95e atmel-samd: Add a heap based cache for writing to flash. 
The code will fallback to the flash scratch space when the GC
cannot allocate us enough memory.
 2016-10-21 15:44:09 -07:00
Scott Shawcroft
bb1822faea atmel-samd: Support external flash on the Metro M0 w/Flash.

Scott Shawcroft
306c921ed1 atmel-samd: Rework mass storage interaction with underlying block 
storage to use micropython's VFS interface.

This makes mass storage work with any VFS implementation rather
than a single one.

Scott Shawcroft
14f25337e7 atmel-samd: Fix FAT by giving the option of 4k sectors. 
This causes the FATFS struct to have the ssize member because
sector size can be anywhere between 512 bytes and 4k bytes.

7e08347d5c atmel-samd: Support composite CDC and mass storage USB device.

7d8929c470 atmel-samd: Add I2C support. 
This commit also introduces a new shared-bindings directory which is used to store the common Python -> C binding code. By having a shared directory we can ensure that the Python API across ports is the same. Each port will have a corresponding common-hal directory which provides definitions for the C api used in the shared-bindings code. That way the compiler can enforce the C api.

To migrate to this new shared API create a common-hal directory within your port and change the Makefile to compile both the shared-bindings and common-hal files. See atmel-samd/Makefile SRC_BINDINGS for an example.

0c4f9b878a Enable REPL over USB. 
All of the code was there except the linker was failing to clear the bss section because I added too many .zeros. The should have only been the exported globals that start with _ like _szero = .. Fixing that and turn on the usb transmit fixed everything.

8f26d181c3 Blinking the LED works. Clocks should be set up correctly. 
Everything works fine without USB being plugged in but faults (I think) when USB is plugged in. This is switched away from the USB code from the bootloader onto the USB code thats generated by Atmel Studio using the high level classes from ASF.
