I think it's better not to provide a UART0 global at all than one that
does nothing.

Ayke van Laethem 9673ad3774 all: move Register{8,16,32} values into runtime/volatile
This avoids duplication of code. None of the smoke tests have changed
their output.

Ayke van Laethem 94b8214529 machine: refactor pins to be of Pin type 2019-05-26 20:48:50 +02:00
Ayke van Laethem e0cf74e638 avr: use register wrappers that use runtime/volatile.*Uint8 calls
This avoids the //go:volatile pragma on types in Go source code, at
least for AVR targets.

Ron Evans 4f4d7976c6 Add core support for multiple UARTs (#152)
* machine/uart: add core support for multiple UARTs by allowing for multiple RingBuffers
* machine/uart: complete core support for multiple UARTs
* machine/uart: no need to store pointer to UART, better to treat like I2C and SPI
* machine/uart: increase ring buffer size to 128 bytes
* machine/uart: improve godocs comments and use comma-ok idiom for buffer Put/Get methods

Ayke van Laethem 9392ef900d avr: add support for the digispark
Blinking the on-board LED works. Nothing else has been tested yet.
