Re: Need sample code for ILI9488 LCD on SPI Interface

There are two sets of pin configuration in tftspi.h, one for ESP_WROVER_KIT and one for other boards, you should modify the pins defines in the second set (starting with #define PIN_NUM_MISO 19 // SPI MISO)
I have tested this library on 4 different boards with 3 different displays and never had a problem.
Yes, you can try to change #define SPI_BUS VSPI_HOST to #define SPI_BUS HSPI_HOST
Can you give more details what exactly hapens when you try to run the example?
