NANO ESP32 with Adafruit HX3857 3.5 TFT

[jgadelman06]

I can't get my NANO ESP32 to work with my Adafruit 3.5 TFT. All I get is a white screen. It works fine with Adafruit libraries.

Driver I uncommented:
#define HX8357D_DRIVER

Pin setup I uncommented:
// ###### EDIT THE PIN NUMBERS IN THE LINES FOLLOWING TO SUIT YOUR ESP32 SETUP ######
// For ESP32 Dev board (only tested with ILI9341 display)
// The hardware SPI can be mapped to any pins
#define TFT_MISO 47
#define TFT_MOSI 38
#define TFT_SCLK 48
#define TFT_CS 21 // Chip select control pin
#define TFT_DC 18 // Data Command control pin
//#define TFT_RST 17 // Reset pin (could connect to RST pin)
#define TFT_RST -1 // Set TFT_RST to -1 if display RESET is connected to ESP32 board RST

Read_User_Setup returned the following:
[code]
TFT_eSPI ver = 2.5.34
Processor = ESP32
Frequency = 240MHz
Transactions = Yes
Interface = SPI
Display driver = 8357
Display width = 320
Display height = 480

MOSI = GPIO 38
MISO = GPIO 47
SCK = GPIO 48
TFT_CS = GPIO 21
TFT_DC = GPIO 18

Font GLCD loaded
Font 2 loaded
Font 4 loaded
Font 6 loaded
Font 7 loaded
Font 8 loaded
Smooth font enabled

Display SPI frequency = 27.00
[/code]

I also tried calling pins out as D12, D11, D13, D10, D9, as well as 12, 11, 13, 10, 9.
I have no clue what I'm doing wrong. Any help would be much appreciated.

I have the same issue with an Adafruit ST7789 1.54 screen.
Anyone ?

This may help for the interface connections:

Thanks for responding. The video gave me some new ideas, and I finally figured it out after several hours of tinkering. In the IDE, I had to go to tools>pin numbering, and select "by GPIO."
