The LCD delay registers configure a delay mode (0=no delay, 1=delay on rising edge, 2=delay on falling edge), not a tick count. Rename the LL layer functions and parameters to reflect this, and add lcd_ll_set_data_delay_mode for esp32s31 and esp32p4.
esp_hal_cam
⚠️ 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_cam component provides a Hardware Abstraction Layer for
- Camera Controller
- Image Signal Processor (ISP) 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, parameter settings). 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.
