ST7735 display only shows glitchy lines

I bought a few ST7735 displays off eBay and am having some trouble getting it to display anything except some glitchy lines.

Here is how I wired everything up:

Imgur: The magic of the Internet (The red line near the top is from the sticker on the display)

And this is what I get:

Imgur: The magic of the Internet

#include <Adafruit_GFX.h>
#include <Adafruit_ST7735.h>
#include <SPI.h>

Adafruit_ST7735 LCD[] = { 
    Adafruit_ST7735(22, 24, 20, 21, -1),
    Adafruit_ST7735(23, 25, 20, 21, -1)
};

void setup() {
    for (int i = 0; i < 2; i++) {
        LCD[i].initR(INITR_144GREENTAB);
        LCD[i].fillScreen(ST7735_RED);        
    }
}

void loop() {
    for (int i = 0; i < 2; i++) {
        LCD[i].fillScreen(ST7735_GREEN);
    }
}

|500x459

|375x500

Just connect one display at a time.

I still get the same lines with 1 display connected.

OK, well that will be how you start to address the problem.

Next, you need to read the instructions and post what code you are using. I'll be out of here as I presently have no familiarity with graphic displays. :roll_eyes:

To insert images, you have to use the URL of the image itself, not the page on which it appears. You can make corrections to previous posts using the "More -> Modify" link at the bottom right of that posting.
