Just in case you’re thinking of upgrading to Arduino IDE 2.0.0, I just found out that it freezes when you use large text files like your image files. So it’s best to use the latest nightly build, which has the fix, until the IDE 2.0.1 comes out. Hope this helps you or someone 👍🏾🤓
I had to switch from 1.8 to 2.0 because of Java issues. 2.0 has it's own new set of quirks like changing the board your using every time you unplug it and changing setting when you do a library update like the TFT_eSPI
@@VolosProjects Yeah, but your video was about scrolling the image and that's the part of the code you didn't present. What seems obvious to you might be a mystery for a beginner. Also you could cover how to avoid flicker and other details that are useful. Most of your videos seem rushed. My advice is to prepare a little bit better before you film and to not rush so much. You have the knowledge, you just have to find a way to present it better. Thanks for your work, I appreciate it!
I see, I agree with you, my videos are rushed ,it is still hard for me to explain code and I dont have much time for better preparation. I am trying to make one video per week. I have my full time job, 2 month old kid and house i need to finish. I hope quality of my videos will improve in future.
That's very cool. I'm wondering if you could use a similar project with a screen that has touch and be able to manually scroll the image. Hopefully I'll be alive next week to see your next video as well...
I like to make a simple "smart watch" with one of these smaller screens- minus all the internet and mobile connectivity. All I want from it is: Time & Date (DD/MM/YY)- maybe the current temp and humidity. Maybe also current UV index. Would that be too complex to be compact?
Many thanks for this video. I appreciate you being able to put out such informative stuff so often, I know you’re a busy guy. I’ll have fun looking at your code. Also, Jessica Alba, Wolverine, burgers and beer will always bait me 😉 If she asks, tell your wife Pete made you do it 😂 Take care 👏🏾👍🏾🤓
Instead of writing 32400, just put in screenW*screenH. Then you can remove the comment, because you've replaced the magic constant with self-documenting code. (there is no optimization to be gained by calculating constants by hand)
I already have an Arduino mini computer! Thank you for your Video!Let me ask you a question,esp32 How do read the video from the SD card and play it on the TFT screen?
I live in Croatia, and i am not affected by war. (exept high prices of fuel and energy ) ... you are right accent is similar. At begining of video i stated that my wife will kill me becouse that scroling picture (good looking girl). So it was just joke :)
@@VolosProjects Good. Wives tend to kill with their look and the silent treatment, but that is just how it is. Never stopped me - after all I am a bloke and the body works like the body works - why hide it?
I'm tring your code on a esp32 and a ili9341 dysplay, and runs fine with width 240px and height 135px, but if I change the parameters to 320px and 240px and the unsigned short imageS[32400]={0} to unsigned short imageS[76800]={0} in order to fit the screen, I get this error during compilation: DRAM segment data does not fit How can I fix it?
@@VolosProjects My intent was to perform only the vertical scroll of an image. I managed to get it to work by dividing the ili9341 screen vertically into two parts. I have replicated your code for the left and right sides using the same imageS variable and now it works perfectly. All this hassle is to avoid memory allocation problems during the compilation. But now I should read the image from a micro sd card, instead of an .h file. I am trying to read the image from sd and dynamically convert it to a uint16_t variable but i am not having success. Do you have any idea?
@@VolosProjects you are right, that's why it wasn't working with uint8_t arrays in my tests. Is it possible to read image from sd card instead of .h file? I'm not able to convert the Image on the fly in a uint16_t array.
hi volos, amazing work with the project, im curious as how to make a background and foreground sprite. where the background is dynamic and the foreground is static like an aircraft attitude direction indicator? this is the code that I have now, it works perfectly but the 'ArrowSprite' which is the fixed aircraft symbol flickers when pushed onto the screen therefore I was thinking of making a composite sprite but I don't know how to get started. please advise. #include #include "Back.h" #include #include #include "Arrow.h" Adafruit_MPU6050 mpu; #define I2C_SDA 20 #define I2C_SCL 21 #include "frame.h" TFT_eSPI tft = TFT_eSPI(); // Initialize library for the TFT screen TFT_eSprite AH_Sprite = TFT_eSprite(&tft); // Create a sprite object TFT_eSprite ArrowSprite = TFT_eSprite(&tft); // Create a sprite object TFT_eSprite TranSprite = TFT_eSprite(&tft); // Create a sprite object void setup() { Wire.begin(I2C_SDA, I2C_SCL); // Initialize I2C communication tft.begin(); // Initialize TFT display tft.setRotation(0); // Set TFT rotation AH_Sprite.setSwapBytes(true); // Set byte swapping AH_Sprite.createSprite(240, 640); // Create a sprite tft.setPivot(120,160); ArrowSprite.createSprite(96,23); ArrowSprite.setSwapBytes(true); TranSprite.createSprite(240,640); if (!mpu.begin()) { tft.println("Failed to initialize MPU6050! Check wiring and connections."); while (1); // Infinite loop to stop further execution if MPU6050 not found } } void loop() { sensors_event_t a, g, temp; mpu.getEvent(&a, &g, &temp); // Read sensor data int angle = map(a.acceleration.y, -10, 10, 90, -90); // Map y-axis tilt to angle range int y = map(a.acceleration.x, -10, 10, 0, tft.height() - 640); // Map x-axis tilt to vertical range int OF=0; y += 160+OF; AH_Sprite.fillSprite(TFT_BLACK); // Clear the sprite AH_Sprite.pushImage(0, 0, 240, 640, Back); // Place background image on sprite // Update sprite's pivot point for rotation and vertical movement AH_Sprite.setPivot(120, 320 + y); // Adjust pivot point for both rotation and vertical movement // Rotate and draw the sprite based on accelerometer data // Since we're not using a physical device to display it immediately, you'd need to handle the sprite display to the TFT after rotation if needed ArrowSprite.pushImage(0,0,96,23,Arrow); ArrowSprite.pushToSprite(&AH_Sprite,72,145,TFT_BLACK); AH_Sprite.pushRotated(angle); // Rotate sprite, making the background transparent }
