I have a SeeedStudio Wio Terminal.
I'm using this lib in VS Code with PlatformIO but the lib
don't use the `SPICOM` variable when it's a generic device.
Steps to reproduce (using a Wio Terminal):
* Create a project using PlatformIO
* Add the TFT_eSPI lib to the project
* Add in the build flags these lines
```
build_flags =
-DUSER_SETUP_LOADED=1
-DILI9341_DRIVER=1
-DHASSPI=1
-DSPICOM=LCD_SPI
-DTFT_CS=LCD_SS_PIN
-DTFT_DC=LCD_DC
-DTFT_RST=LCD_RESET
-DTFT_BL=LCD_BACKLIGHT
-DTFT_BACKLIGHT_ON=HIGH
-DTFT_BACKLINGT_V=2000
```
* Compile and transfer to the device
=> only backlight works
