Your library is amazing! I tested it with Arduino and it's really fast. Now I have a Raspberry Pi Pico and although it is a 120mhz board, the examples I found are really slow. Is there a CircuitPython or MicroPython version of this library?

Thanks for a nice library...

I have a ST7789 TFT 320x240 and I can get it to work with some of the examples, but the rest of screen outside 240x240 is flickering as assumed it should be in this mode...

I’m not an experienced Arduino programmer, but I’ve tried to change to 320x240 in the example code, but I am not sure exactly where to set it up, if possible...?

Is there any chance to update or change code in this driver for use 320x240 TFT screens...?

Thanks!

Does this library work with esp32 boards ?
Would it be possible to modify the pins to match esp32 pins ?

Good day cbm80amiga, kindly review the downloading link. file cant be downloaded

HI, this is really a good library, thank you for your contribution.

I'm testing this library on an Arduino UNO board just as the YouTube video shows: LINK
connecting my IPS 240x240 display directly on UNO

but my display are always "black" (or just very blurry with only some pixel moving)
I only get the correct image in a split second when I press the reset button.

After searching for a while, I see a comment under that YouTube video saying adding some 1K resister will help.

so I have tested it and can confirm adding an 1K resister on each communicate pin (SCA/SCL/RES/DC) will resolve this problem.

I'm wondering this might be a "hardware issue" but not a "software issue", might have something to do with 5V instead of 3.3V system
so maybe we can add some instruction / notice on "README.md" or even in the file to help future user ?

if the author thinks this is a thing worth to do, I can test most boards on my hands and create a pull request.

Any suggestion will be appreciate, or may be I can be wrong on the hole thing(?)

I'm using the Adafruit_Benchmark sketch in examples. I have all the pins connected to where they are on the script, but it just gives me a compile error. I can't figure out why. Here's the screen.

I cannot get this library to work with an IPS 240x240 TFT? I have tried 2 different IPS to ensure it was not a hardware issue. Both have the backlight illuminate; but will not operate. I have tried several of the example codes and none work at all. I have ensured the connections and I am using an Arduino Nano. I read past issues and even tried placing a 1k resistor on each communication line; still only a blank screen with the backlight lit. I am using 3.3v and the wiring is correct. Anything I might be able to try? Thanks

Hello, really good and fast library! Just one thing, i am using an 1.14" 135x240 pixel display and the origin (x 0, y 0) is not on the display but on the outside so just can see the half of the displayed things. I tried to edit the defined size in the .h and .cpp file but I can't get it to work.

I would be very happy if there is a solution for my problem!

Hi, i im using ST7789V2 (tied CS to GND) and all is working except resolution, in library i see that is defined WIDTH and HEIGHT of 240x240 but i need to be 240x280 because i need to get all pixels working on my display.

Here is code that i write from example library:

`#include "SPI.h"
#include "Adafruit_GFX.h"
#include "Arduino_ST7789_Fast.h"

#define SCR_WD 240
#define SCR_HT 280

#define TFT_DC 7
#define TFT_RST 8
//#define TFT_CS 9
#define CS_ALWAYS_LOW

Arduino_ST7789 tft = Arduino_ST7789(TFT_DC, TFT_RST);

void setup() {
// put your setup code here, to run once:
tft.init(SCR_WD, SCR_HT);
tft.begin();
tft.setRotation(1);
tft.fillScreen(BLACK);
//tft.setCursor(0, 0);
//tft.setTextColor(WHITE); tft.setTextSize(2);
//tft.println("IPS 240x280 ST7789V");
}

void loop() {
// put your main code here, to run repeatedly:

}
`

And here is the picture what i was getting as output:

As you can see screen is black for 240x240 (library limit), i define 240x280 but it have white color and that is missing 40 pixels....can you please update your library to be working with higher resolutions others that 240x240?

Thanks.

Hello.

Firstly thank you very much for providing for a great library. I am struggling to get 4 or 8 bit bitmap with palette working with your bitmap example. A 24 bitmap generated with your bmp2src works fine, but if I use a 4 or 8 bit it doesn't work.
Would you be able to provide an example please or steer me in the right direction?

Thanks in advance,

Regards

Is there a possibility to add readPixel(x,y) to the library. I hear that the ST7789 support reading the GRAM.
Thanks

I'm using arduino mkr wifi 1010 and I'm getting this error:
Arduino\libraries\Arduino_ST7789_Fast-master/Arduino_ST7789_Fast.h:19:10: fatal error: avr/pgmspace.h: No such file or directory
#include <avr/pgmspace.h>

Will this ever work for a SAMD board or am I just missing a library ?

Please tell me this library is different from the library https://github.com/cbm80amiga/Arduino_ST7735_STM?
The one that is intended for microcontrollers is weaker than stm32 and therefore you made the work with SPI a little more curtailed in it?
Or is this library Arduino_ST7789_Fast really fast and will work on stm32?
I am trying to get your libraries to work on the new arduino core for stm32.

As far as I found by asking google it's something about the SPI.

Hello!

How to make dynamic text.

There is a text and a value after the text, how to make the value not overlap each other?

void setup(){
   while (1) {
      sens_signal = analogRead(IR_SENSOR_PIN);
      lcd.setCursor(10, 30);
      lcd.setTextColor(RED);
      lcd.setTextSize(2);
      lcd.println("IR");
      lcd.setCursor(40, 65);
      lcd.println("SENSOR");
      lcd.setCursor(100, 90);
      lcd.println(sens_signal);
      if (millis() - reset_timer > 5000) break;
    }
}

I need to display a digital value from the sens_signal variable, it changes and overlaps, it turns out nonsense.

lcd.println(sens_signal);

Hey I have the 12 pin ST7789 display but instead of using the 7 pin module display I am trying to connect the bare 12 pin display itself. I used this library to upload the Hello World sketch to my Arduino and it works fine on the 7 pin module version of the display. However when I wire up the 12 pin the screen flashes white before going blank.

Here are my connections:
All 4 GND of display: GND on Arduino,
LEDK: 3.3V Power,
LEDA Arduino GND,
VDD: 3.3V,
D/C: D7 on Arduino,
CS: GND,
RES: D8 on Arduino,
SDA: SDA on Arduino,
SCL: SCL on Arduino.

Since this works with the module version I assume it's a wiring issue. Anyone else here able to use the bare 12 pin screen with Arduino? Appreciate any help I can get, thanks.

Hello!
I used your Benchmark script (actually some other as well with the same result). The display does not show full pictures but only some of dots. If I press reset button it display as normal untill I release the button. I use Arduino (Genuino) UNO.
What can be an issue?

Hi I’m trying to get the library to work with a 135x240 display. I’ve modified the initialisation and screen rotation elements in the .cpp which all seem to be specifically ported from adafruit for the 240x240 display. But haven’t got it working yet.

Has anyone attempted to modify the code for other resolution?
