to create a new `SpiBusDevice` instead of directly instantiating the
struct. `SpiBusDevice::new` takes care of setting up the CS line to be a
default-high output, too, which the raw struct doesn't.
Add a feature for the ESP32-C2 to`esp-hal-common` and update some `cfg`s
Organize the `esp-hal-common` imports and exports and update to include the ESP32-C2
Removes a lot of generic arguments and hard-codes the `SpiBusController`
and `SpiBusDevice` to work with the `Spi<T>` defined in the HAL instead.
This allows us to access the `cs_signal()` trait function from `T:
Instance`, which we need to connect/disconnect the CS I/O as
appropriate.
* Update the build script to inject a configuration value for the enabled chip
* Update all cfg gates to use the new symbols instead of the chip features
* Inject architecture and core count symbols as well, update as needed
* Organize the imports and exports of `esp-hal-common`
* WIP: common/spi: Implement `SpiDevice`
to get shared access to an SPI bus directly via the HAL.
* WIP: common/spi: add SpiBusDevice::new
to create instances via a function call.
* esp32/examples: Add example for spi device trait
* common/spi: Finish "SpiDevice" implementation
for esp32. Abandons the approach of having the user pass in some generic
mutex in favor of creating the Mutex as part of the API so it isn't
exposed to the user in the first place.
* common/spi: Add more thorough docs
* esp32/examples: Fix example for eh1 "SpiDevice"
* common/spi: Implement `SpiDevice` for xtensa arch
and move the code into a submodule that is fenced with conditional
compilation directives.
* esp32/examples: Update spi device example
to the changed APIs for the timers and clocks, and add more transmission
tests to the example code.
* common/spi: Create devices from buscontroller
directly, instead of offering only the `new` method.
* common/spi: Finish `SpiBusDevice` trait
from embedded-hal 1.0.0-alpha.8.
* esp32: Update `SpiBusDevice` usage example.
* common/spi: Fix mutex types for xtensa32 esp
because the esp32/esp32s3 can use `SpinLockMutex`, whereas the esp32s2
has access only to `CriticalSectionMutex`.
* common/spi: Implement `SpiBusDevice` for riscv
based esp32c3.
* general: Add examples for spi device loopback
to all esp variants.
* common: Use esp_backtrace in spi_eh1_device examples
* common/spi: Update module documentation.
* common/spi: Use `critical_section::Mutex`
to unify locking across all esp variants.
* esp32c3-hal: Fix spi device example
* esp32c3/examples: Fix typo in used spi pins
