The ``adc_digi_config_t`` struct is modified on esp32c3: configuration
of clock divider factors are not provided anymore. The SARADC sampling
frequency is provided instead. In this way, we can handle the frequency
limit better.
- add lock for single read and continuous read APIs
- update onetime read start singal delay for hardware limitation[*]
- move adc_caps to soc_caps.h
- update license dates
[*] There is a hardware limitation. If the APB clock frequency is high, the
step of this reg signal: ``onetime_start`` may not be captured by the
ADC digital controller (when its clock frequency is too slow). A rough
estimate for this step should be at least 3 ADC digital controller
clock cycle.
ESP32 in revision0 and revision1 uses touchpad to provide
current to oscillate xtal 32k. But revision2 and revision3
do not need to do that.
Note: touchpad can not work and toupad/ULP wakeup sources
are not available when toupad provides current to xtal 32k
During HAL layer refactoring and new chip bringup, we have several
caps.h for each part, to reduce the conflicts to minimum. But this is
The capabilities headers will be relataive stable once completely
written (maybe after the featues are supported by drivers).
Now ESP32 and ESP32-S2 drivers are relative stable, making it a good
time to combine all these caps.h into one soc_caps.h
This cleanup also move HAL config and pin config into separated files,
to make the responsibilities of these headers more clear. This is
helpful for the stabilities of soc_caps.h because we want to make it
public some day.
This commit adds the feature where the TWAI ISR will continue to
run even if the cache is disabled. Whilst cache is disabled, any
received messages will go into the RX queue, and any pending TX
messages in the TX queue will be transmitted. This feature should
be enabled using the CONFIG_TWAI_ISR_IN_IRAM option.
Replace periph_module_enable/disable by periph_wifi_bt_common_module_enable which are in IRAM.
AddIRAM_ATTR periph_ll_wifi_bt_module_enable_clk_clear_rstandIRAM_ATTR periph_ll_wifi_bt_module_disable_clk_set_rstto fit O0 optimization level.
Delete duplicated spinlock and counter.
This commit adds TWAI driver support for the
ESP32-S2. The following features were added:
- Expanded BRP support
- Expanded CLKOUT Divider Support
- Updated example READMEs
The SPI bus lock on SPI1 introduces two side effects:
1. The device lock for the main flash requires the
`CONFIG_FREERTOS_SUPPORT_STATIC_ALLOCATION` to be selected, however this
option is disabled by default in earlier IDF versions. Some developers
may find their project cannot be built by their old sdkconfig files.
2. Usually we don't need the lock on the SPI1 bus, due to it's
restrictions. However the overhead still exists in this case, the IRAM
cost for static version of semaphore functions, and the time cost when
getting and releasing the lock.
This commit:
1. Add a CONFIG_SPI_FLASH_BYPASS_MAIN_LOCK option, which will forbid the
space cost, as well as the initialization of the main bus lock.
2. When the option is not selected, the bus lock is used, the
`CONFIG_FREERTOS_SUPPORT_STATIC_ALLOCATION` will be selected explicitly.
3. Revert default value of `CONFIG_FREERTOS_SUPPORT_STATIC_ALLOCATION`
to `n`.

* Add test support for ESP32S2
* Add loop back test
* Support chip internal connection, no external wiring required.
* Delete the relevant codes of PDM of ESP32-S2 ll layer.
* fix dac dma mode issue
* Let `[ignore] case` return to freedom
1) Because this test uses its own ISR, we need to release it with `esp_intr_free` instead of `pcnt_isr_service_uninstall`.
2) `pcnt_evt_queue` needs to be created before the interrupt is registered and needs to be released at the end of each case.

* Support chip internal connection, no external wiring required.
The following commit refactors the CAN driver such that
it is split into HAL and Lowlevel layers. The following
changes have also been made:
- Added bit field members to can_message_t as alternative
to message flags. Updated examples and docs accordingly
- Register field names and fields of can_dev_t updated
