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.

Ayke van Laethem 17b5b6ec5b all: use less magic in memory-mapped IO
Don't store addresses in the values of registers, this leads to problems
with char arrays (among others). Instead, do it like it's done in C with
raw addresses cast to struct pointers.

This commit also splits gen-device.py, as AVR and ARM have very
different ideas of what a register is. It's easier to just keep them
separate.

Ayke van Laethem 90fb0ee4eb Add AVR support
This requires support in LLVM, as AVR support is still experimental. For
example, in bindings/go/build.sh, add
-DLLVM_EXPERIMENTAL_TARGETS_TO_BUILD=AVR to cmake_flags.
