Wow! So well explained. Thank you!

Can you make a tutorial on how to use RGB Color Wheel in SquareLine Studio with this screen to control RGB LED.

@Elecrow Месяц назад

Thank you for your kind advice, i will let you know when I update the video related to this! 😊

@@Elecrow Thank you, I'm really looking forward to it

Hi Can you make a tutorial on how to load in a PNG image as either .png, or .bin stored in SPIFFS, and SD Card? I have an application which uses a few images, and no space to use the C source code on the target

@Elecrow Месяц назад

Thank you for your attention. We will collect your all suggestions. If we plan to release related tutorials, we will notify you through subscription.

@@Elecrow Thanks for the prompt reply, I really appreciate it. Just one thing to add, the main thing that seems a bit complicated, and would need a bit of attention, is mounting the SPIFFS, and SD card to LVGL, loading PNG, bin, JPEG, and gifs seems to be quite straight forward. I look forward to seeing a tutorial about this, thank you again

Hi, thanks a lot for you help. I'm trying to use I2C to set an communication channel to another ESP32S, but the ELECROW display generate an error (see following). Could you tell me what I can use to avoid this and communicate using a master/slave similar method?

The GPIO error is due to the use of code with a pin number of "-1" in the initialization of display and touch. There is no need to modify it, and these errors will not have any impact. As for the I2C issue, the touch function is already occupied. You can first watch the video in lesson 8, which explains how to use the I2C function: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Hs3UPth3JhM.html

@jumbodumbo1472 3 месяца назад

Is it possible to use external function in ui_events? Let's say from main file.

@Elecrow 2 месяца назад

Yes, but there may be errors due to compilation problems in C and C++, so I would recommend leaving the action to the ino file and the event is only used to change the flag.😊

Sorry for the English translation. I am French speaking. This is really an excellent tutorial. Well done, well explained, really excellent. I have a small question. I have the 7 inch screen. When I download the code, everything works perfectly. However, when I press the ON button or the OFF button, the whole image moves slightly from left to right, a little oscillation. Is this normal?

@Elecrow 2 месяца назад

This may be because the speed of the 7-inch display driver is too high, you can appropriately reduce a little, in the gfx_conf.h file, find the 7-inch driver interface code, find cfg.freq_write = 16000000; You can change it to 14000000 and it will have a noticeable effect.

@@Elecrow I just did the test. Wonderful. The problem is completely solved. Thank you very much for the extremely fast response.
