Hi
I have just bought a cheap 1.8" Serial SPI TFT LCD Module Display off Ebay and I'm trying to connect it to an Arduino Uno. The module has 16 pins -
LED-
LED+
SD CS
SD MOSI
SD MISO
SD SCK
TFT CS
TFT SCK
TFT SDA
TFT AO
TFT RESET
NC
NC
NC
VCC
GND
Obviously LED- and LED+ are for the backlight and the connections are -
Board Arduino
LED- GND
LED+ 3.3V
VCC 5V
GND GND
I have installed the Adrafruit Arduino ST7735 and GFX libraries. As the board also has an SD card reader, I would like to use this as well as the TFT display. As the board has pins for both the TFT and SD, I need guidance in how to wire it up to my Uno. Any help would be appreciated,
I've managed to get the TFT example sketches working using the following wiring -
LED- GND
LED+ 3.3V
SD CS
SD MOSI
SD MISO
SD SCK
TFT CS 10
TFT SCK 13 (SCLK)
TFT SDA 11 (MOSI)
TFT AO 9 (DC)
TFT RESET 8
NC
NC
NC
VCC 5V
GND GND
I now need to know how to wire the SD pins so that I can display a bitmap that's on an SD card. Any ideas?
SORTED!!!
I managed to get the SD card (and TFT) working by patching the SD MOSI to TFT SDA and the SD SCK to TFT SCK . I also wired up SD CS to Arduino 4 and SD MISO to Arduino 12.
Now I can load graphics from the SD card and display them.
Here's the full wiring -
LED- GND
LED+ 3.3V
SD CS 4
SD MOSI 11
SD MISO 12
SD SCK 13(SCLK)
TFT CS 10
TFT SCK 13 (SCLK)
TFT SDA 11 (MOSI)
TFT AO 9 (DC)
TFT RESET 8
