I understand your point, but for me is not possible to create a full video, instead of a video it will be a course of several hours. But if you see the project on github, all steps are properly documented. You need to understand video creation is difficult job, requires several days. I hope u understand.

This is a good demo showing, however, the so briefly description of demo is sadly poor-friendly to new learner. That's to say, expert does not need to watch simple demo like this. New learner cannot understand this type of deadly-brief type of description.😂

I understand your point, but if you ask me I want to improve but the problem is time and money, this is my hobby but I get zero money in return, if you ever have created a video you might understand how difficult and time consuming it is. So that's why I have to keep it really short. This is one of the best performing videos on my channel, so I am assuming not all but some people might get benefit from this.

Hi, how should the TFT-ILI9341 be connected to the ESP8266? Can you tell me the connection pins? Thank you.
@EmbeddedLaboratory 3 ай бұрын
Actually tft is not connected with esp8266. Here Aruino Mega is used and tft ili9341 shield is used, so ili9341 is connected with arduino. Then with Arduino serial port esp8266 is connected, here esp8266 has AT firmware, and from Arduino mega I configure the esp8266 using at command to get data from openweather map. Please watch previous two videos to understand properly. Thanks

hello, im struggling to get the touch part to work. i am using arduino ide and lvgl there. the displaying of the ui works fine, but the touch for lvgl doesnt get detected. the touch is working, just not with lvgl. i went and checked the code, and my guess is that the my_touchpad_read function isnt being called. can you try and help me out? This is very frustrating, and i would like to finally be able to use this tool. I am using the demo code, but i just cant get the touch to work. I also added an extra function which is a simple if(getTouch){serial.print"bla bla"}, in the same code in the loop function, and if i touch, it detects the touch on serial, just lvgl is not processing it. am i missing something? do i need to add something to the standard my_touchpad_read function? Please help :((
@EmbeddedLaboratory 4 ай бұрын
Please check the value of this macro "LV_INDEV_DEF_READ_PERIOD" LVGL basically creates a timer that runs as per the period specified, u can add a print statement in your touch read function, and it should work. If u have your code on Git Hub, u can share the link and I can try to check for mistakes. The first step is to check whether the calling to you touch function is happening or not, and the next step is whether the touch is working. Please check this link also, this project is based on Arduino kzbin.info/www/bejne/iH-kdKCEacl-jck

Yes is possible then you don't need lvgl buffers, which means you don't need display manager file. And if you are referring a newer version of this project then you don't need display manager and gui manager.

I followed your video and the display just flickers a little. I'm using an ESP WROOM 32 board and a 2.8" SPI TFT Module. both the controller and display work with other examples. I compiled with both 5.2 and 4.4.6 esp-idf and lvgl version 8.3.11 and 9.0.0 without success. I have wired the SPI as shown in tft.h except for TFT_PIN_DC which is wired to GPIO_NUM_4 instead of GPIO_NUM_0 (there is no 0 on this board). I was hoping you might have a suggestion? Thanks in advance for any help.
@EmbeddedLaboratory 5 ай бұрын
As mentioned in the video also, first try to understand where the problem is. Start with ILI9341 drivers, try to display a pixel or fill the screen, and then see if this is working. The next step is to make the touch work. Then comes the LVGL integration part. My project only supports ILI9341 and LVGL 8.3.11. If you really want to learn, follow the small steps I have mentioned, it will take time, but the output and learning will be worth it.

Hi. great video thank you. Please help me solve when I am using a round display (240x240)the corners of calibration script do not show in the "corners" and I can't go the next step. This is happening even the LVGL examples.
@EmbeddedLaboratory 6 ай бұрын
Thanks for the appreciation. Unfortunately, I don't have any round displays with me, even I am not aware if they use resistive touch or capacitive touch. But calibrating the touch is very simple, Arduino based library hides the complex stuff inside, I would suggest you to go slow and try to understand the touch and fine tune it. Recently I did the same for XPT2046 resistive touch screen controller, u can take reference from here. github.com/xpress-embedo/ESP32/blob/master/ESP-IDF/LVGL_TemperatureHumidity/main/xpt2046.c

For deployment on Android, you should have an Android kit configured, and you have to build the MQTT library for the Android kit and then the same project should work out of the box.

However, this is a display diagram with a 32 pin ribbon connector! And in the pictures there is a display with a 14 pin ribbon connector and this display does not have pin 15. How to change, force another address change in this small 128x32px display? I need to control two displays and cannot use a multiplexer.

Hi, you posted on the incorrect video, but anyways fine. To answer your question, first thing is that I don't know which module you are using. The following lines are from the datasheet. "“SA0” bit provides an extension bit for the slave address. Either “0111100” or “0111101”, can be selected as the slave address of SSD1306. D/C# pin acts as SA0 for slave address selection. “R/W#” bit is used to determine the operation mode of the I2 C-bus interface. R/W#=1, it is in read mode. R/W#=0, it is in write mode. " So basically, u have to play with D/C line, in one module it should be connected to HIGH signal and in another to LOW signal. And if this pin is not available, I don't think you can do much.
