The data obtained from the sensor must be updated in the UI on the screen. This video covers how to update the screen by passing data through a queue based on FreeRTOS' task.

this is the same approach on my project! It allow the software to much much smoother in the interaction between touch and widgets!

@legobuildingsrewiew7538 Месяц назад

Hell yeah! Can you make a video on dynamically updating E Ink displays? Maybe on one other stm32 chips with lots of RAM and programming those

@mars3142 Месяц назад

Do you plan to do some ESP-IDF examples on this device with LVGL9? That would be awesome.

@ThatProject Месяц назад

I don't have any plans yet, but I'll give it a try.

@andrisetianabrata Месяц назад

How about to take data from global variabel And some task give the variabel for the value?

@ThatProject Месяц назад

There is no problem using global variables. As I mentioned in the video, I set up my system like this to minimize delay. There is no right answer here.

@Kevin-sx6we Месяц назад

Is the core 0 just for Wi-Fi application?

@ThatProject Месяц назад

Yeah. As far as I know, Bluetooth and WiFi are pinned to core 0 in the Arduino environment.

Is this the whole error message? Have you set up the lv_conf.h file?

i have an excelent idia . Please let some text-to-speech read your context. I really fell tortured by the way you you speak. your projects are great but for god sake stop this nightmare I really want to stay subscribed,

@ZefStudio Месяц назад

No please we don’t need more generic text-to-speech content in the world. Please just be yourself. You’re doing great and are understandable. Dude people from all over the world speak English and it’s ok that it’s in their own way, get out of your bubble and deal with it.

@mr.bianchirider8126 Месяц назад

You sound fine. Great project.

@sinmim1 Месяц назад

@@ZefStudio i really struggle. it Not personal. He is great at all other means. The English is not my native language also so it's really harder for us to understand

Just hit the CC button at the bottom to get auto-captions; problem solved :)

@murielcordeiro1231 8 дней назад

I bought a display but every code o try to upload to it gives this error Even tried googling it but nothing Someone help pls E(91) esp_core_dump_flash: incorrect size of flash dump image: 0

@ThatProject 7 дней назад

Did you set it to Default in the partition settings? Or did you choose Huge App? In the case of the Huge app, you can see this error message because the core dump partition does not exist. However, if you are not using coredump partition, you can ignore this message.

@murielcordeiro1231 6 дней назад

So, we are using the default partition settings The weird thing is that the display is reseting it self or something like that. We thought it had something to do with that error cause it runs through the whole code Can send more info if needed, we are completely lost honestly

@ThatProject 5 дней назад

@@murielcordeiro1231 That's weird. Going back to the beginning, you said you got the same product as me, the WT32-SC01 Plus. Is that right? Is it set to OPI PSRAM in PSRAM settings? This must be set to QSPI PSRAM.

@murielcordeiro1231 4 дня назад

@@ThatProject Oh, actually, it’s not the same product. Sorry about that. I found your channel, which works with a lot of display types, and thought it would be helpful to ask for your assistance. However, I couldn’t find another way to contact you (I actually sent a message on Instagram a few days ago), so I decided to reach out here. Thank you so much for helping us solve the partitions problem! Now, we’re encountering an issue with the driver (ST7262). The only library we know that works with it is Arduino_GFX, but we’re having trouble even getting a simple “Hello World” to run.
