Setup
Platformio.ini changes
In the platformio.ini
file, uncomment the TFT_eSPI
line within the [common] section, under lib_deps
:
# platformio.ini
...
[common]
...
lib_deps =
...
#For use of the TTGO T-Display ESP32 Module with integrated TFT display uncomment the following line
#TFT_eSPI
...
Also, while in the platformio.ini
file, you must change the environment setup to build for just the esp32dev platform as follows:
Add lines to section:
default_envs = esp32dev
build_flags = ${common.build_flags_esp32}
-D USERMOD_ST7789_DISPLAY
-DUSER_SETUP_LOADED=1
-DST7789_DRIVER=1
-DTFT_WIDTH=240
-DTFT_HEIGHT=240
-DCGRAM_OFFSET=1
-DTFT_MOSI=21
-DTFT_SCLK=22
-DTFT_DC=27
-DTFT_RST=26
-DTFT_BL=14
-DLOAD_GLCD=1
;optional for WROVER
;-DCONFIG_SPIRAM_SUPPORT=1
Save the platformio.ini
file. Once this is saved, the required library files should be automatically downloaded for modifications in a later step.
TFT_eSPI Library Adjustments
If you are not using PlatformIO you need to modify a file in the TFT_eSPI
library. If you followed the directions to modify and save the platformio.ini
file above, the Setup24_ST7789.h
file can be found in the /.pio/libdeps/esp32dev/TFT_eSPI/User_Setups/
folder.
Edit Setup_ST7789.h
file and uncomment nad changep GPIO pin numbers in lines containing TFT_MOSI
, TFT_SCLK
, TFT_RST
, TFT_DC
.
Modify the User_Setup_Select.h
by uncommentig the line containing #include <User_Setups/Setup24_ST7789.h>
and commenting out line containing #include <User_Setup.h>
.
If your display includes backlight enable pin, #define TFT_BL with backlight enable GPIO number.
