Tutorial: Getting TFT LCD displays working

Tutorial: Learn how to get common TFT LCD displays working with Teensy or Arduino. Shown is how to use these SPI displays with Arduinos and Teensy. Wiring, code, and a short example using a 2.8 inch TFT is included. Whether you use the Adafruit_ILI9341 or ILI9341_t3 libraries, hopefully this lesson will help you get your display working.

Good to see examples for the Teensy

[@KrisKasprzak]

Many more examples with teensys are coming…

Waw, this was really interesting and usefull ! I got my mind made up now !

[@KrisKasprzak]

Glad it was helpful!

if a lcd display says 5v then all the sdl sca pins use 5v and vice versa?

[@KrisKasprzak]

really depends on the display. Some accept 5v0 on Vcc but have an onboard regulator for power and data pins *should* be 5 volt tolerant. If the display has an SD card some mfg's put series resistors to protect the card. you can always use a voltage divider for data lines if the display has issues

@@KrisKasprzak st thr 5v display operates at 5v and the card reader operates at 3.3v?

[@KrisKasprzak]

@@taranagnew436 Card readers run on 3V3, most displays are 3V3 as well. Depending on the display they may have level shifters or resistors to drop the voltage to a safe level.
