Jeff Epler c0029e1d97 Don't lose half of the processor's serial number 
Before this change, `microcontroller.cpu.uid` returned values
where the top 4 bits of each byte were zero, because of
an incorrect bitmask used in this function.

Ayke van Laethem fa55b15ac6 extmod/vfs_fat_file: Implement SEEK_CUR for non-zero offset. 
CPython doesn't allow SEEK_CUR with non-zero offset for files in text mode,
and uPy inherited this behaviour for both text and binary files.  It makes
sense to provide full support for SEEK_CUR of binary-mode files in uPy, and
to do this in a minimal way means also allowing to use SEEK_CUR with
non-zero offsets on text-mode files.  That seems to be a fair compromise.

Jeff Epler a7e3c74fed Autocreate files that prevent MacOS indexing of the CIRCUITPYTHON dive 
.. the price of this appears to be about 112 bytes of flash and 12
bytes of RAM, according to the stats printed during the build.

It also uses up 4 directory entries (out of 128), but does not reduce
the number of blocks usable for storing file contents.

These are the same items noted in the Adafruit README for Trinket M0
as preventing MacOS indexing.

Closes: #689

Jeff Epler dddfad6594 UART: Fix maybe-uninitialized diagnostic 
The following error occurs when building with gcc 5.4.1 (debian stretch):

common-hal/busio/UART.c:104:83: error: 'sercom_index' may be used uninitialized in this function [-Werror=maybe-uninitialized]
                   sercom_insts[rx->sercom[j].index]->USART.CTRLA.bit.ENABLE == 0) ||

It may be related to the addition of rx-only UARTs; gcc is unable
to infer the intended relationship between have_tx and sercom_index
being set (I am still not entirely confident of it myself)

This saves 380 bytes on the Arduino Zero build. (More pins ==

Scott Shawcroft 7a3f86d184 Check usb_busy up front in usb background function. 
Waiting to do so risks accidentally queueing another response.

Hopefully fixes #655 but we'll let @jerryneedell confirm.
 2018-03-14 10:32:41 -07:00
Scott Shawcroft c37ade9aeb Correct NO_TIMER index value for SAMD21. 
We check validity by ensuring it's lower than the total number of
timers. 0 is a terrible number for the NO_TIMER value because its
valid even though it shouldn't be.

Scott Shawcroft 8157248189 Move usb read finish into interrupt. 
Having the `active_read = false` in the background function left
a chance that a new_write occurs before active_read is set to false.

In that case, we'll read the appropriate data rather than write it
and never clear the active write.

Hopefully fixes #655.
