Merge pull request #634 from dhalbert/3.0_UART 
Implement UART for 3.0 + related fixes.
 2018-02-21 23:07:27 -05:00

5f101f3535 Add dummy UART implementation to nrf so it builds with UART turned on. Also add OneWire. 2018-02-21 22:53:17 -05:00
Dan Halbert
9b4477e1dc Implement UART for 3.0 + related fixes. 
1. UART: ported to ASF4. Allow rx-only and tx-only. Add .baudrate r/w property.

2. Make NeoPixel timing deterministic by turning off caches during NeoPixel writes.
3. Incorporate asf4 updates:
  a. async USART driver
  b. bringing Atmel START configuration closer to what we use
  c. Clock initialization order now specified by CIRCUITPY_GCLK_INIT_1ST and _LAST.
4. supervisor/port.c: Move commented-out clock-test pin setting to correct location.

QSPI. The previous spi_flash functions are now called external_flash
to minimize confusion.

b001c0711b Correct _etext location; clean up .ld files 
1. Make _extext and _sidata coincide. Old _etext location did not include
.ARM.exidx sections, which were usually absent but not always. So flash
data was copied to RAM in wrong place.
2. Use decimal constants with "K" and "M" suffixes in .ld files instead
of hex constants, to make them easier to read and check for accuracy.

Merge pull request #443 from dhalbert/3.0_spi

312444bbd2 non-DMA SPI working; adding this now for testing; will continue with DMA 
Also, fixed pin mappings for rev B Metro M4:
swap PA12 and PA13 on SPI 2x3 header
swap A3 and A5

Comment out all frozen modules in CPX again to make room while waiting
for SPI flash.

971bd7e9a6 atmel-samd: Improve MSC reliability. 
* Be more liberal with critical sections to ensure ordering.
* Correct usb_busy so that it is busy when no errors occur on
  transfer. I believe it worked before because it would be false
  momentarily until a second transfer was attempted and a busy
  error was returned, therefore setting usb_busy to true. That
  risks the first "failed" transfer completing before a second one
  is attempted.

7292984204 Implement busio.I2c. 
* Added asf4_conf/samd*/hpl_sercom_config.h
* Adjusted clocks in peripheral_clk_config.h.
* Put some frozen libs back in CPX for testing.
* Implement common-hal I2C
* Add samd*_peripherals.h in parallel with samd*_pins.h for common
  functions and data.
* Store SERCOM index in pins table for convenience.
* Canonicalize some #include guard names in various .h files.

simpler reset of SERCOMs; remove unused routine
