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
