Project 136: Thermal Imager Project Update 4: 2.2″ TFT LCD Screen and Multiple Slaves on SPI Bus

I have received and connected my 2.2″ Adafruit TFTLCD display. Unlike my previous display, I had no issues connecting this one.

In additon to the Adafruit Core GFX library, I had to include the specific driver library for this display, which was ILI9340.

I was able to run through all of the basic “Hello World” tests from the graphic test program with no issues.

This display can use both the high-speed SPI bus and a slower connection type. Since my RAM module also uses SPI, I had to do some research into this system in order to connect both of them to the SPI bus at the same time. I will post in some detail on this later.

Now all I need to do to build the Thermal Scanner is connect up the SD card slot on the TFT display, and connect the Flir Dev Kit.
