using 1.44" TFT with HUZZAH32 ESP32

Post by earthres »

I have a feeling this isn't a very smart question, but trying the sample code for displaying a bunch of stuff on your 1.44" TFT, I can't seem to assign pins that work. How should I make the connections to a HUZZAH32-ESP32? Do I need to assign the RESET pin? (It doesn't seem to need to be connected when I use this display on a UNO.)

This should be the the ADA# 2088 TFT, correct?

The graphicstest code provides the Huzzah32 pins.

Code: Select all

#if defined(ARDUINO_FEATHER_ESP32) // Feather Huzzah32
  #define TFT_CS         14
  #define TFT_RST        15
  #define TFT_DC         32

Here are the pin connections that I'm using and now -- 12 instead of 32 for TFT_DC was just my arbitrary choice. The graphicstest code works fine and the data I generate in my application also works as it should. Apparently for displaying code-generated content on the display, the RST pin doesn't actually have to be attached to anything. Right?
#define TFT_CS 15 // TCS
#define TFT_RST 14 // RST
#define TFT_DC 12 // D/C
#define TFT_MOSI 18 // SI
#define TFT_SCLK 5 // SCK
