* Update esp32_smartdisplay.c (#247) configurable backlight delay * removed dc_as_cmd_phase (#259) * Updated boards * Fix backlight duty validation and update error messages for CST816S touch controller * DMA (#264) * Add DMA manager for optimized bitmap transfers and update related functions * Refactor DMA initialization and add completion callbacks for optimized bitmap transfers * Add DMA support for optimized bitmap transfers across multiple display panels * Refactor LVGL display flush functions to utilize optimized DMA helpers - Removed redundant DMA completion callbacks from individual display files. - Introduced a new header file `esp32_smartdisplay_dma_helpers.h` for common DMA functions. - Implemented `smartdisplay_dma_flush_with_byteswap` for SPI/I80 panels to handle byte swapping and DMA transfers. - Added `smartdisplay_dma_flush_with_rotation` for parallel panels to manage software rotation and DMA transfers. - Updated all display panel files (GC9A01, ILI9341, ST7262, ST7701, ST7789, ST7796) to use the new helper functions for flushing. - Enhanced DMA initialization with standardized logging through `smartdisplay_dma_init_with_logging`. - Improved error handling and logging for DMA operations across all display panels. * Uncomment default_envs for esp32-8048S070C in platformio.ini * Refactor DMA helper functions and clean up code formatting for consistency * Update src/esp_touch_cst816s.c Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Update src/lvgl_panel_st7789_i80.c Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Update src/lvgl_panel_st7796_spi.c Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Update src/lvgl_panel_gc9a01_spi.c Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> --------- Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Update subproject commit reference in boards * Update subproject commit reference and refactor DMA initialization and transfer logic * Update subproject commit reference to indicate dirty state * boards * Uint to uint32 t (#270) * boards * boards * boards * renamed uint to uint32_t as it is not standard * Update src/esp32_smartdisplay_dma.c Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> --------- Co-authored-by: manhere <580122+manhere@users.noreply.github.com> Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com>
