* build.zig: Trivial rename around UART test
* mmio: Add writeRaw() to set a full register
* UART: Add TODO for auto baud rate detection
* STM32F30x Initial USART1 output/transmit support
All code assumes default chip clock configuration.
Code assumes STM32F303xB / STM32F3030xC.
Code supports only 8 data bits, 1 stop bit.
* stm32f3discovery @panic() to UART1
This is done by implementing `debugWrite()` for the board,
which only initializes UART1 if that was not yet done,
and flushes afterwards to make sure the host receives all.
* stm32f303: Support UART1 reader
This is done by implementing `rx()` and `canRead()`.
* stm32f303 UART1 correctly support 7 and 8 bits
This includes correctly masking the parity bit
on reads.

* stm32f303 UART1 simplify parity code
* stm32f303 I2C rough initial code
Allows only writing and reading single bytes.
* stm32f3 i2c: enable debug 'logging'
* Add a few comments
* I2C API changes, STM32F303 I2C multi-byte transfers
Now using controller/device terminology, instead of master/slave.
Now using 'transfer objects' to make STOPs and re-STARTs explicit,
and allow using Writer and Reader APIs.
Added 'register' abstraction.
STM32F303 I2C now supports this new API, and multi-byte transfers.
Now waiting for I2C_ISR.BUSY == 0, after setting I2C_CR2.STOP == 1.
Without this, the sequence write-stop-write caused an additional STOP
to be sent immediately the START and address of the second write.
* Make work with regz-generated registers.zig change
* Updated to match regz-generated update
* After #23 repair Reset on stm32, lpc1768
* Clean-up I2C `readRegisters()`.
* Refactor to separate read/write states
* On STM32F303, make second read call fail
Also doc comments to clarify the new API.
* STM32 I2C: Properly support multiple write calls
* I2C STM32: Fix release mode compile error
...on top of an earlier commit on this branch.
* I2C Add 'write register' shorthand functions
* Make sure vector_table is correctly exported
It needs to be a non-`comptime` `var` for `@export` to work properly.
The only 'documentation' for this behavior currently seems GitHub comment
https://github.com/ziglang/zig/issues/5157#issuecomment-618933196 .
This issue was introduced in 1c17304 for PR #27,
which broke at least ARM-based STM32F303.
* fix missing vector table on ARM
* Revert "Merge branch 'fix-vector_table-export' into marnix-master"
This reverts commit 8ea0a74e1031cd0b88abe0283f179f0cf20f450c, reversing
changes made to 355a3618080d28c5da6e044773e6449989355fe5.
* Temp commit for SPI
* Check new I2C target_speed config setting
* Corrected incorrect doc comment
* Initial SPI transfer support for STM32F303
* SPI device CS pin is now used
* Revert accidentally committed debug flag.
* SPI: Add shorthands for 'register-based' devices.
* Additional fix to remove PE3 pin dependency
* SPI: Renames, comments, extracted device-specific code
Specifically,
top-level `Spi` is now `SpiBus`;
and the internal API has an additional `switchToDevice()`,
and receives `DeviceConfig` in more places.
* SPI device: Add `transceive()` method.

ziglang/zig#14181 changed the interface for overriding the log function.
Previously, you would define a public `root.log` function. Now, you
define a `root.std_options` namespace that has a `logFn` decl.

* i2c: pass a config to init
For now, allow setting the i2c target speed
* i2c: allow selecting the scl/sda pins
Similar to the previous commit for uart, this allows specifying the pins for
microcontrollers that support multiple pins for a single i2c peripheral
* stm32f407: add support for i2c
Supports using all I2C peripherals with all their pins in standard mode (fast
mode support will be added in the future).
board: and chip: can be prefixed to the pin to force using a pin defined in the
board or in the chip. Currently though, neither chips or boards are handling
this prefix.
Since this is just used to give priority when parsing the pin, this commit
removes the namespace from the spec passed to parsePin. This isolates the
namespace handling to the Pin type creation, without having to handle it in
chips and boards.
While this does not automate clock configuration yet, at least it allows using
microzig with applications that configure the clock themselves and then declare
the speeds of the various domains.
Without this, all peripheral depending on different clock domanins (e.g. Uart or
I2C on STM32 devices) could only work with the reset frequency.
* Makes AVR UART work.
* Some comment. This is definitly not padding.
* Exports panic, log and log_level from application.
* Implements generic quadrature decoder driver.
* Fixes `@export` bug in AVR interrupt logic. Now we get distinct interrupt vectors.
