ESP8266 connected with ili9488 3.5-inch TFT screen for display +
touch
1. Use TFT_eSPI library
2. Configuration content
2-1)How the device is wired?
VCCLED - 3.3
GND - GND
CS - D8
RST - D4
DC/RS - D3
SD1(MOSI)T_DIN - D7
SCKT_CLK - D5
T_D0 - D6
T_CS - D2
* XXX/XXX indicates that a parallel line is required, which is only
applicable to ESP8266 and ili9488 screens
*Other screens must be adjusted according to the annotations in
User_Setup.h and User_Setup_Select.h, so as to avoid detours!!
2-2). Modify User_Setup.h
Find the User_Setup.h file in the library directory and modify the
annotations according to the model of the TFT screen
#define ILI9488_DRIVER // WARNING: Do not connect ILI9488 display
SDO to MISO if other devices share the SPI bus (TFT SDO does NOT
tristate when CS is high)
Uncomment this driver, and return the default li9341 to the comment
Add two parameters
#define TFT_WIDTH 480
#define TFT_HEIGHT 320
Because I am using a 480*320 screen, there are no corresponding
parameters in the file, so I can add it and use it directly if
there are parameters of the corresponding screen in the file
The file continues to scroll down
Find #define TOUCH_CS PIN_D2 and uncomment (corresponds to the
wiremap port)
2-3) Modify User_Setup_Select.h
Enable #include <User_Setup.h>
Enable #include <User_Setups/Setup20_ILI9488.h> (different
screens search for the corresponding driver according to the
English annotation)
*For other types of screens, you need to open the corresponding
User_Setups/Setup20_ILI9488.h driver file to check whether the pins
defined are the same as those in the wiring diagram.
2-4) Try it for a run
Open the instance -TFT_eSPI-Generic-Touch_calivrate in Arduino
(this instance is called touch calibration, touch must be
calibrated)
Follow the examples provided in the library and play to your
heart's content
