Missing esp_lcd_i80_alloc_draw_buffer

[MartinDavidWaller]

Hi, when I compile with esp32 devmodule, ep32c3 devmodule all is well. When I compile with esp32s3 devmodule I get:

C:\Users\marti\Documents\Arduino\libraries\GFX_Library_for_Arduino\src\databus\Arduino_ESP32LCD8.cpp:824:24: error: 'esp_lcd_i80_alloc_draw_buffer' was not declared in this scope
824 | _buffer = (uint8_t *)esp_lcd_i80_alloc_draw_buffer(_io_handle, LCD_MAX_PIXELS_AT_ONCE * 2 + 16, MALLOC_CAP_DMA);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I have the espressif V3.0.7 boards installed.

I was wondering if there is an easy fix for this?

I have updated to the latest board code from espressif and it all compiles now. Still not got it going though. I'm using an ESP32S3 supermini and the interesting code from your u8g2fonthelloworld code is:

Arduino_DataBus bus = new Arduino_SWSPI(LCD_DC / DC /, LCD_CS / CS /, LCD_SCK / SCK /, LCD_MOSI / MOSI /, GFX_NOT_DEFINED / MISO */);

Arduino_GFX *gfx = new Arduino_NV3007(
bus,
LCD_RST, // RST (Reset pin)
0, // Rotation (0-3)
true // IPS panel setting (true forces color inversion correction)
);

I have a feeling I'm doing something silly but can't see what yet!
