240x320 Video Converter

[Carmelina Olden]

Anyoneknow how to hook this thing up with an UNO and get it working? I can probably figure out the software side, but I'm not confident I have the pins connected correctly. Should the VCC and LED pins both be connected to 3.3V or 5V on the UNO? Which pins are necessary to use? (excluding the touch or SD card).

Naturally I stubble on a possible answer right after I post. So it seems with this shield I need a 5v-3.3v logic level converter for it to work with the UNO. Here is a link with someone who apparently had the same issue.

I'm at work currently so haven't had a chance, plus I'm waiting on a new breadboard since my other one is currently occupied so testing is a pain at the moment. I will give it a try when my new breadboard arrives.

I installed them both and the serial monitor ran through all the display stuff like drawing lines and whatnot, but nothing showed up on the screen. I'm sure it's the hardware side that's my problem. I'm still trying to understand why I need a logic level converter if the arduino has a 3.3v pin I can tap into. I need to do more reading. I think this link will explain it better which I will read after work.

Because the display is looking for 3V highs, not 5V highs.

The display is taking 3V for power from the Arduino 3V supply, but the Arduino outputs are still 0/5V.

Don't fight it, just go with it.

Ok, finally got around to cleaning my breadboard and trying to get this thing working. The first thing I tried was using 1k resistors like one of the links I posted suggested, and it works! The Adafruit demo loaded up and went through the demo stuff.

The problem now, I'm trying to get the "breakouttouchpaint" example to work from their touchscreen library, but again I don't know how to wire this thing. In the code they refer to X positive, X negative, Y positive, and Y negative. They link these 4 to Analog pins 2,3, and digital pins 4,5. Does anyone know what the equivalent is on this board to the Adafruit ones?

You can connect the Touch controller to the same SPI bus as the SD card and the TFT.

Make sure that all the logic levels are 3.3V. Your "resistors" are a bit fierce! 1k0 and 2k2 would be nearer 3.3V.

AFIK, Adafruit do not do a library for the SPI Touch controller chip.

Avoid anything from UTFT unless you are prepared to waste the GPIO pins.

UTFT has only heard of bit-bashing, and will certainly kill any hardware SPI devices on those pins.

This is the part that's confusing me since I'm a newb. Isn't the SPI bus on the UNO consist of pins 10 (ss),11(mosi),12(miso), and 13(sck)? I'm already using those pins for the display to work, so do I share them with the "touch" pins on the touch screen (t_IRQ, t_DD, t_DIN, t_CS, and t_CLK)?

It won't work. It needs both the UTouch and UTFT libraries. I tried it and got an error msg. Problem is the UTFT Library needs a lot of flash memory, and I got a msg saying Sketch uses 33,460 bytes (103%) of program storage space. Maximum is 32,256 bytes. Even the website states:

Wait! It kind of works. Not sure why I thought UTFT was needed, must have loaded a different example. I'm trying the "uTouchButtonTest" example and it's letting me click on the numbers, but something is off with the alignment. Hitting "clear" gives me 9, "enter" gives me 7, and whatnot. At least its progress

Ok, got it working! I did the calibration example and updated the UTouchCD.h file with the results. Now everything works great. Thanks guys! Now that I know it works I can try figuring out how to make my own menu system on it.

I have been playing around with the touch screen a bit, and there's an issue I can't figure out. Basically when I'm using the ILI9341_due library, the colors often get messed up, or the screen sometimes stays white (even though I believe the sketch is loading underneath).

When it messes up I run the adafruit "graphictest" example and it plays fine, and in the process seems to reset everything. I'm convinced it's some kind of conflict with the reset button, either from the library side or my connection from the Reset pin directly to the 3.3V pin on the Arduino Uno.

Below is some simple code, the only change in the code is the library I'm using, and all it's supposed to do is display a sequence of different colors on the screen (Black, Red, Green, Blue, and Yellow) repeatedly.

It still doesn't explain why when I load a ILI9341_due sketch after powering up the Arduino, the screen stays white, where's when I run the Adafruit one it always loads. There's still something off about the way it resets/refresh's. Funny part is when I load a ILI9341_due sketch, then the adafruit one, for a split second I can see the ILI9341_due sketch appear on the screen before the adafruit one starts.

As I said before, the reset pin on the touch screen is connected to the 3.3V on the Arduino. My setup is just like this, except I changed 4 of my resistors to to 2K2 as someone suggested. Do I need a logic level converter for the Reset pin also?

Guys please suggest me a good video converter software for openSUSE to covert videos into multiple formats.it will be easy if it ask me to covert videos for a specific device like i-pod,Nokia,Samsung mobiles.thanks in advance:-)

Nowadays, digital devices like mobile phones use images as wallpapers. Users want to use their custom images as wallpaper. But the image they have can be larger than the mobile screen. On the other hand, a photo converter is an online platform that allows its users to change the dimension or resolution of a larger image into a smaller one. In addition, CompressKaru has a variety of image resizing and converting tools that can be accessed with a single click without installation.

A 240320 pixels (width x height) converter is developed using the latest algorithms and techniques. So, there is no need to worry about cropping and losing image quality. Moreover, this tool will analyze the image itself and then optimize it according to the quality of the image. You can bookmark this tool by pressing the Ctrl +D button at the same time for future use.

This online resizer used to resize your image file dimension to 240 x 240 pixel picture file. so this act as converter tool works for convert the photo to 240x240 px resolution online. It helps to set profile photo for social media. resize the passphoto and signature to 240*240 for online gove, private job applications.

To convert the image dimensions like width and height to constant 240*240 px, here its best web application for resize it. simply upload the photo to FreeImageKit website. and picture dimensiona are automatically changed to 240x240 px.

We offer you this online pixel converter in order to effectively convert pixels to millimeters (mm). All you need to do is just type the number of pixels (px) and the resolution value to calculate those in millimeter (mm).

An introduction to the inline formatting context. Explores line-height and vertical-align properties, as well as the font metrics. Understand how text is rendered on screen, and how to control it with CSS.

We are planning to switch a component of the font converter back to the one that was used in 5.3 and prior versions. That will hopefully fix the majority of the issues that users are seeing with fonts in 6.0.

1. Click the "Choose Files" button to select multiple files on your computer or click the "URL" button to choose an online file from URL, Google Drive or Dropbox. Image file size can be up to 200M. You can use file analyzer to get source image's detailed information such as image size, resolution, quality and transparent color.

2. Set target image format, image quality and image size. You can use the original image size or select the "Change width and height" option and enter a custom image size. The format is [width]x[height], for example: 1920x1080. The image quality option only works on a few image formats such as JPG, WEBP or AVIF. The value ranges from 1 (lowest image quality and highest compression) to 100 (best quality but least effective compression). If this value is blank, the converter will use the estimated quality of your input image if it can be determined, otherwise 92. The target image format can be JPG, PNG, TIFF, GIF, HEIC, BMP, PS, PSD, WEBP, TGA, DDS, EXR, J2K, PNM, SVG, etc.

3. Click the "Convert Now!" button to start batch conversion. It will automatically retry conversion on another server if one fails, please be patient while converting. The output files will be listed in the "Conversion Results" section. Click icon to show file QR code or save file to cloud storage services such as Google Drive or Dropbox.

Image files are composed of digital data in one of image file format that can be rasterized for use on a computer display or printer. An image file format may store data in uncompressed, compressed, or vector formats. A raster graphics image is a dot matrix data structure, representing a generally rectangular grid of pixels, or points of color. As opposed to the raster image formats, vector image formats contain a geometric description which can be rendered smoothly at any desired display size.
