# Pure/Hybrid micropython lvgl display driver for
# ili9341, ili9488, ili9488g, gc9a01, st7789 on ESP32
#
# For ili9341 display:
#
# Build micropython with
# LV_CFLAGS="-DLV_COLOR_DEPTH=16"
# (make parameter) to configure LVGL use the same color format as ili9341
# and prevent the need to loop over all pixels to translate them.
#
# For ili9488 display:
#
# Build micropython with
# LV_CFLAGS="-DLV_COLOR_DEPTH=32"
# (make parameter) to configure LVGL use the ARGB color format, which can be
# easily converted to RGB format used by ili9488 display.
#
# Default SPI freq is set to 40MHz. This means cca 9fps of full screen
# redraw. to increase FPS, you can use 80MHz SPI - easily add parameter
# mhz=80 in initialization of driver.
#
# For ili9488g (gCore) display:
#
# Build micropython with either
# LV_CFLAGS="-DLV_COLOR_DEPTH=32"
# or
# LV_CFLAGS="-DLV_COLOR_DEPTH=16 -DLV_COLOR_16_SWAP=1"
#
# Default SPI freq is set to 80MHz.
#
# For gc9a01 display:
#
# Build micropython with
# LV_CFLAGS="-DLV_COLOR_DEPTH=16"
# (make parameter) to configure LVGL use the same color format as ili9341
# and prevent the need to loop over all pixels to translate them.
#
# Default SPI freq is set to 60MHz as that is the maximum the tested display
# would support despite the datasheet suggesting that higher freqs would be
# supported
#
# For st7789 display:
#
# Build micropython with
# LV_CFLAGS="-DLV_COLOR_DEPTH=16"
# (make parameter) to configure LVGL use the same color format as ili9341
# and prevent the need to loop over all pixels to translate them.
#
# Critical function for high FPS are flush and ISR.
# when "hybrid=True", use C implementation for these functions instead of
# pure python implementation. This improves each frame in about 15ms!
#
# When hybrid=False driver is pure micropython.
# Pure Micropython could be viable when ESP32 supports Viper code emitter.
#
# ili9488 driver DO NOT support pure micropython now (because of required
# color convert). Pure micropython is only supported the for ili9341 and
# gc9a01 displays!
