C47D 31247430df lvgl_tft: Remove gpio_pad_select_gpio from drivers init functions 2022-01-11 21:28:26 -06:00
Carlos Diaz 17eb416ef8
Update helpers and drivers to handle LVGLv7 and v8 versions (#161)
* [lvgl_helpers] Cleanup and misc code cleanup

Checks for SPI_HOST_MAX symbol before using it.

Rename lvgl_driver_init to lvgl_interface_init because it now only initialize
the interface bus for display drivers, we still need to remove the indev
drivers from here.

Use types defined in spi_types.h for spi host (spi_host_device_t) and
spi dma channels (spi_dma_chan_t).

Also add a couple of symbols to avoid using magic numbers

* [lvgl_helpers] Reduce usage of if defined in lvgl_interface_init

* [lvgl_helpers] Fix spi dma channel for ESP-IDF versions <= 4.2

* [examples] Update hello_world to call lvgl_interface_init

* Add lvgl_get_display_buffer_size helper

This helper will allow us to get the calculated display buffer size instead of using a global symbol.

* Implement lvgl_get_display_buffer_size

This API will be used to get the calculation of display buffer size.

* Delete DISP_BUF_SIZE symbols

The same functionality is handled by lvgl_get_display_buffer_size

* Move SPI max transfer size calculation to helper

Use calculate_spi_max_transfer_size to calculate the SPI max transfer size for the SPI master configuration

* Remove SPI_BUS_MAX_TRANSFER_SZ definition

Same functionality is now handled in calculate_spi_max_transfer_size

* Update display buffer size calculation

Use lvgl_get_display_buffer_size helper instead of DISP_BUF_SIZE symbol

* Update example to LVGL v8

Add comments about changes from:
- LVGL v7 to LVGL v8
- Configuration helpers and display drivers

* Update lvgl_helpers.c

* Update sh1107 driver

* Update EVE driver

Check for symbols used in previous implementations before trying to use them
and add a fallback temporary implementation when not found.

The falback implementation isn't tested with hardware.

Symbols:
- DISP_BUF_SIZE
- SPI_TRANSFER_SIZE

* Update uc8151d driver

* Update jd79653a driver

* Update ra8875 driver

* Update il3820.h

Check for LV_HOR_RES_MAX and LV_VER_RES_MAX before trying to use them

* Update lvgl_helpers.c

Check for ESP-IDF version before trying to use spi_dma_chan_t type

C47D a0e915eebc Remove TAG from LVGL log API
The filename is appended at the beginning of the log output by default, we don't need to do it.

Rop Gonggrijp 7b571a7fc7 LV_DISP_USE_RST
Allows to not allocate a GPIO for display reset: some may have that pin tied or attached to a Power management IC.

Supersedes PR from @usedbytes doing same but only for IL9341, this is for all supported displays.
