This is the example wiring used for the sketch testing.
|
||
|
|
|
||
|
|
You must not define the TFT_CS pin in the TFT_eSPI library if you are
|
||
|
|
using two independant displays. Instead the chip selects (CS) must be
|
||
|
|
defined in the "config.h" tab of this sketch. The sketch can then select
|
||
|
|
the dispay to send graphics to.
|
||
|
|
|
||
|
|
If you are only using one display, then TFT_CS can be defined in the
|
||
|
|
TFT_eSPI library.
|
||
|
|
|
||
|
|
The "Setup47_ST7735.h" file was used for the two TFT test using the wiring
|
||
|
|
as shown below:
|
||
|
|
|
||
|
|
Function ESP32 pin TFT 1 TFT 2
|
||
|
|
MOSI 23 -> SDA -> SDA // The TFT pin may be named DIN
|
||
|
|
MISO 19 // Not connected
|
||
|
|
SCLK 18 -> CLK -> CLK // The TFT pin may be named SCK
|
||
|
|
TFT_DC 2 -> DC -> DC // The TFT pin may be named AO
|
||
|
|
TFT_RST 4 -> RST -> RST
|
||
|
|
CS 1 22 -> CS // Connected to TFT 1 only
|
||
|
|
CS 2 21 -> CS // Connected to TFT 2 only
|
||
|
|
+5V/VIN -> VCC -> VCC
|
||
|
|
0V -> GND -> GND
|
||
|
|
+5V/VIN -> LED -> LED // Some displays do not have a backlight BL/LED pin
|
||
|
|
|
||
|
|
The displays used for testing were 128x128 ST7735 displays, the TFT_eSPI library setup file may need
|
||
|
|
to be changed as these displays come in many configuration variants.
