Wiring parallel TFT with ESP32

Question

I have this Parallel LCD TFT. I want to connect it with an ESP32 (NodeMCU). I am using the TFT_eSPI library. In the TFT_eSPI documentation, it says that the connection should be as following:

// The ESP32 and TFT the pins used for testing are:
//#define TFT_CS 33 // Chip select control pin (library pulls permanently low
//#define TFT_DC 15 // Data Command control pin - use a pin in the range 0-31
//#define TFT_RST 32 // Reset pin, toggles on startup
//#define TFT_WR 4 // Write strobe control pin - use a pin in the range 0-31
//#define TFT_RD 2 // Read strobe control pin - use a pin in the range 0-31 
//#define TFT_D0 12 // Must use pins in the range 0-31 for the data bus
//#define TFT_D1 13 // so a single register write sets/clears all bits.
//#define TFT_D2 26 // Pins can be randomly assigned, this does not affect
//#define TFT_D3 25 // TFT screen update performance.
//#define TFT_D4 17
//#define TFT_D5 16
//#define TFT_D6 27
//#define TFT_D7 14

P.S. My tft does not have DC PIN. So, I wired nothing to GPIO15

After I wired the TFT, the ESP32 stop responding to flash process. and obviously, it did not run anything(even if I flash it without the screen and then wiring it again)

My question is:

• What is the mistake did I do? How can I link this parallel LCD with ESP32

• LotPings: How did you wire the 5V pin of the display? When attached to an uno/mega2560 it gets power over this (and possibly the 3v3) pin.
• Majenko: DC is the same as RS (or LCD_RS on your board).
• Humam Helfawi: @LotPings External 5v power supply

Sorry for the Late reply, I had the same issue. You cant have anything connected to pin 15 or 2 during flash
