* pinout yamls removed
* machine: implement default UART pin configuration for Embedfire boards
* flash command moved to chip level so VS Code plugin can select bare chip
* machine: add support for alternate pin mode configuration
* add build targets for embedfire on py32
* add support for embedfire target in GNUmakefile for py32
* lib/py32-svd: remove duplicate DBGMCU.IDCODE CODE field
Update submodule to fix duplicate SetIDCODE/GetIDCODE method
declarations in the generated py32f002bxx.go device file.
* update subproject commit reference in py32-svd
* refactor: update CPU frequency handling in machine and runtime packages
* refactor: replace ConfigureUARTPin function with direct pin configuration in UART setup
* SetAltFunc documentation for GPIO pin alternate functions
* refactor: improve UART write and flush error handling with timeout
* machine/py32: generalize UART driver to any USART
Add a per-instance setup func to the UART type so the driver is no longer
hardwired to USART1. DefaultUART stays USART1; add UART2 (USART2) in a
separately build-tagged file since py32f002x parts lack USART2. RX IRQ
handlers reference runtime-assigned vars to break the init cycle, and setup
is assigned in the var initializer so it runs before InitSerial.
Add the py32f003_32k_4k target (32K flash / 4K RAM).
* Add canonical PY32F002, F003, and F030 density targets
Use CMSIS/pyocd device names for target files and build tags. Add all F003 and F030 densities plus F002A/B, correct F002B to 24K flash and its own startup file, fix the F030x8 pyocd target, and update Embedfire inheritance.
* Add targets for all PY32 CMSIS devices
* Support all PY32 register layout variants
* machine/py32: use generated register definitions
* machine/py32: fix alternate-function documentation
* machine/py32: report the configured CPU frequency
* machine/py32: use unsafe.Add for GPIO ports
* machine/py32: bound and yield UART polling
* machine/py32: configure UART pins from UARTConfig
* build: use the current PY32 SVD repository URL
* test: cover PY32 UART register layouts
* machine/py32: restore dynamic CPU frequency tracking
* machine/py32: share the USART TX-ready bit
* targets/py32: scale system stacks with RAM
* machine/py32: keep clock state internal
* targets/py32: normalize generated metadata
* machine/py32: normalize GPIO configuration
* machine/py32: fix T020 UART setup
* machine/py32: reduce clock variant files
* machine/py32: clean up UART variants
* machine/py32: decouple UART clock capability
* lib/py32-svd: use organization repository
* runtime/py32: name 24MHz HSI encodings
* machine/py32: derive startup clock from capability
* machine/py32: use generated USART clock mask
* machine/py32: name T020 8-bit UART mode
* ci: include PY32 in sharded smoke tests
* runtime: remove PY32 HSI frequency workaround
This change implements a new "scheduler" for WebAssembly using binaryen's asyncify transform.
This is more reliable than the current "coroutines" transform, and works with non-Go code in the call stack.
runtime (js/wasm): handle scheduler nesting
If WASM calls into JS which calls back into WASM, it is possible for the scheduler to nest.
The event from the callback must be handled immediately, so the task cannot simply be deferred to the outer scheduler.
This creates a minimal scheduler loop which is used to handle such nesting.
This is only very minimal support. More support (such as tinygo flash,
or peripheral access) should be added in later commits, to keep this one
focused.
Importantly, this commit changes the LLVM repo from llvm/llvm-project to
tinygo-org/llvm-project. This provides a little bit of versioning in
case something changes in the Espressif fork. If we want to upgrade to
LLVM 11 it's easy to switch back to llvm/llvm-project until Espressif
has updated their fork.
These files don't really belong in this repository. It's better to
generate them automatically from a source, like the one provided by the
avr-rust project. So a new command `make gen-device-avr` has been
provided for this purpose.
