config LCD_PANEL_IO_FORMAT_BUF_SIZE
int "LCD panel io format buffer size"
default 32
help
LCD driver allocates an internal buffer to transform the data into a proper format, because of
the endian order mismatch. This option is to set the size of the buffer, in bytes.
config LCD_ENABLE_DEBUG_LOG
bool "Enable debug log"
default n
help
Wether to enable the debug log message for LCD driver.
Note that, this option only controls the LCD driver log, won't affect other drivers.
if SOC_LCD_RGB_SUPPORTED
config LCD_RGB_ISR_IRAM_SAFE
bool "RGB LCD ISR IRAM-Safe"
default n
help
Ensure the LCD interrupt is IRAM-Safe by allowing the interrupt handler to be
executable when the cache is disabled (e.g. SPI Flash write).
If you want the LCD driver to keep flushing the screen even when cache ops disabled,
you can enable this option. Note, this will also increase the IRAM usage.
config LCD_RGB_RESTART_IN_VSYNC
bool "Restart transmission in VSYNC"
default n
select GDMA_CTRL_FUNC_IN_IRAM # need to restart GDMA in the LCD ISR
help
Reset the GDMA channel every VBlank to stop permanent desyncs from happening.
Only need to enable it when in your application, the DMA can't deliver data
as fast as the LCD consumes it.
