I've been looking far and wide for simple videos that explain esp32 NOT using the arduino framework. Thank you for your work and I hope to see more of your content!

[@AntonioJose-uk8ln]

It's so frustrating as a developer that EVERY ESP32 tutorial ends up being based on the Arduino framework (even when it's not explicitly said in the title). I'm glad to have found this video.

[@mohamedabdelrehem7698]

please don;t stop posting and finish this ESP playlist it is the best as you start from down ♥♥

Dude, i just found your videos and you have blown my mind. Im sad you only have 4 videos and I encourage you to make may more. No one explains thime details if hiw to set this stuff up but you. I havent watched all 4 yet. In fact i stipped 1/2 way through a different video so i could come here and see fron the start how it's done.. thank you

[@YuriR]

Hi Yakine, thank you so much for the feedback! I'm happy you liked the content. 😉

[@yakine13]

@@YuriR Quick question my friend: I'm trying to save data to the SPIFFS storage partition to retrieve them later. But seems like SPIFFS is depreceated for LITTLEFS, though I can't define this on my .csv partition... Can you clarify the confusion? Is littlefs just a library on top of SPIFFS? Also, do you have any recommendation to make a webserver where I can download this .txt file? Thank you

Cheers buddy!

[@fcf8269]

So this is great if you are writing a program and then upload it to the chip, but what if you want to access these files say from a serial port console? Is the ESP32 able to operate as if it was a minimalist terminal to load and save files from its flash? Or do you access its flash only by making a C app and uploading it to the ESP32 chip? Thanks.

[@LordHaehnchen]

Hi Yuri. I like the way you explain things. Very strait forward. Im learning programming with Circuitpython on Esp32 and Cortex M4 microcontrollers from Adafruit. Right now im diving in coding State Machines. My biggest issue is that i can not use the debugger from VSC as the Code runs on the board itself. You made a video about the JTag debugging option. Is it possible that you can check if there is a way to debug circuitpython on VSC in a similar way? That would be so awesome…. I cant find any approach in the internet so far…. Cheers

[@tonydiamond4118]

Sorry for the long question, I'm not that knowledgeable in this area and am very much a noob, but I think this is the solution I'm looking for but not sure if it's too ambitious or if I'm even in the right place. I have a project idea with the EPS32 & a tft display, would this work to store gif or mjpeg files so that animations can be called up and play on a tft display? For example: I have an animation of a character, it'll have 3 states, asleep, awake, & wave and they would be triggered by some event like motion or vibration. Would it be possible to store those states in separate folders on the flash memory and then call them up to a tft when triggered? I had the esp32 hooked up to a small 1.44" tft display and had tft_espi examples running, I made an attempt to add littlefs to try the idea I mentioned above for storage and somehow ruined the screen or the esp32. The screen is stuck on white and cannot get the espi examples running. Idk how that's relevant to this other than I'm competent enough to wire the controler to the tft but once I get to the code I'm lost AF.

Please get rid of the noise music.

[@YuriR]

Please let me know any suggestion of music.

[@kevinslattery5748]

@@YuriR Thanks for listening. Please have no music at all. It's all noise. Your dialect is hard enough to understand, let alone trying to make out you're saying through the noise. Also you have very technical content so background music simply doesn't match. I'd like to understand and focus on what you're saying not to enjoy music. The 2 are incompatible. Please no music at all. If anyone wants music they can play their own private music in their own living rooms from their own source.

[@dbl_play]

@@kevinslattery5748 TBH, I think the dialect of YuriR is not so hard to understand and he is doing also a great job, and the music not that bad, I would say like this is not borring :). But Yuri can take a decision on this one! :)

the #include "freertos/FreeRTOS.h" line is always red on my VSCode, I already modified the path setting on intellisense with the "C:/esp/esp-idf/**" but still. How can I fix it? Is it even a problem?
