- Removed conditional definitions for various RCC_ATOMIC macros across multiple files, replacing them with a unified PERIPH_RCC_ATOMIC() macro. - Updated instances where specific RCC_ATOMIC macros were used to ensure consistent usage of PERIPH_RCC_ATOMIC(). - Deleted unused uart_share_hw_ctrl.h file as its functionality is now integrated into the new structure.
esp_hal_i2c
⚠️ This HAL component is still under heavy development at the moment, so we don't guarantee the stability and backward-compatibility among versions.
The esp_hal_i2c component provides a Hardware Abstraction Layer of I2C for all targets supported by ESP-IDF.
In a broad sense, the HAL layer consists of two sub-layers: HAL (upper) and Low-Level(bottom). The HAL layer defines the steps and data that is required to operate a peripheral (e.g. initialization, start and stop). The low-level is a translation layer above the register files under the soc component, it only covers general conceptions to register configurations.
The functions in this file mainly provide hardware abstraction for IDF peripheral drivers. For advanced developers, the HAL layer functions can also be directly used to assist in implementing their own drivers. However, it needs to be mentioned again that the interfaces here do not guarantee stability.
