If you're using just one SPI device no problem, because CS (chip select) when LOW means this device is ACTIVE (in use).

The TFT should have one pin to control the brightness. Is this your TFT http://forum.arduino.cc/index.php?topic=200126.0? See the link, if it help you with wiring or another tip.

i use library
https://github.com/esp8266/Arduino/tree ... it_ILI9341

Platform Arduino ide ESP8266

Try 50-60 resistor and write post. Thank you.

Same as mine (it has touch panel )

Try connect the TFT LED pin, between SDO (MISO) and SCK, direct to 3.3V or 5V.

I used SMING, tonigth will try with Platform Arduino IDE ESP8266

any ideas?
