hey man you look like Dave Pensando

how to flash the esp32 lvgl 2.8 module to nerd miner?

I am a newbee trying to learn about this board. I followed as much as I understand your TH-cam instructions but getting the following errors. Please help me understand these errors and how to fix them? Thanks.

13:10 well don't worry just use an external usb to serial straigth to the esp32 , load an OTA sketch, so u can do it via wifi, and you're off :)

Devil is in the details! I was wondering why the USB wasn't getting detected. Turns out you disconnect the DSP from the programming board[ICP1]. Connect ICP1 alone first (sigmastudio USB module turns green), THEN connect the DSP. Dumb indeed! Thanks for sharing Rob!

does it work well with a finger or thumb?

What did he take? Needthat.

Hello! Thanks for the awesome video! Do you know what is the voltaje input for the EXT Power Conn : P1 ( VIN, TX, RX, GND )?. I would like to use an external battery so not sure where I should use the 3.7v or if I need an stepup to use 5v Thanks!!!

One needs laser focus on ground loops. with two boards. Thats why I usally make two monoblocks and 2x psu in one case. Avoiding ground loops is easier that way.

THANKS

I went to your git page I think I found to sound thing.

please send the code for the sound

It clips to protect little ears

I love that sound

Hi, I'm looking to make a small display that will get info from an API, turn the JSON into something readable, and display it on the screen. Do you reckon that would be relatively straightforward to do with this? I know how to call and handle APIs, but unsure about displaying the data on the screen. Once set up, is it similar to any other Arduino display?

there are some youtube fixes for the audio issues which are quite simple. google esp 32 audio fix th-cam.com/video/6JCLHIXXVus/w-d-xo.html

비싸도 좀더 잘 만들어서 팔자

Wow ! A most interesting project and explanation of how each component works. I also thoroughly enjoyed the discussion later and also the demo. 🤔😀👍

"NC" normally closed contact.

Worth noting that the ESP32 can also do QSPI output, so you could run 4 sets of shift registers at the same speed. People have also used the I2S peripheral to push DMA out of 8 channels at once I believe.

I just inherited this lens from my dad. He used with the Nikon Vintage 70's or 80's camera. Can I get an adapter and use it with my Sony A7IV?

www.amazon.com/AITRIP-Development-ESP32-2432S028R-Bluetooth-240X320/dp/B0CKYVPWX9 the link i used to buy it on amazon is dead but another has sprung up ;-)

what you a building is called a guie with sound

i have the same board and i want to display a gif on repeat. I'm a complete novice and have been researching to no avail. can you please help?

Don't know if you intended to use it commercially, but SquareLine Studio is free :)

What is quality of sound?

My expectation from a display with a processor would be to at least get a simple Hello World example with a couple of widgets to be able to expand from. I find my projects wind up on a 2 line or 4 line I2C display for simplicity and reliability.

What are you using for a power supply?

i have simple ESP32 with 50 inches screen - very simple

Could be a good board. It's cheap because there are so many bad designs on it. For example The i2c connector is wrong. Such a shame

Rewatching your video again. I have done this a few times to to get as much info as posible as both Sound Inports and Dayton audio dont have much simplified info on this product. I have got very far in programing and implimenting the dsp in my project . Thanks your your advise and williness to help. I have this thing buried inside a case but need to have the pots on the front panel as opposed to indide the case. I am willing to desolder the pots on the board and solder wires to get external pots. my question is there must be a simpler way. Do you have any idea how to do this without de soldering? Thanks

Elecrow customer support suggests switching to LovyanGFX to correct the screen shift issue and so far in my testing it works. forum.elecrow.com/discussion/578/7-inch-esp32-s3-random-screen-shift#latest

I'm guessing, but the connectivity problem is likely due to the fact that the PCB designer did not seem remove the copper parallel to the antenna on the ESP32 module. At least that's what it looks like from what I can see of it on the elecrow web site. A ground plane really close to a pcb trace antenna will change the range that the antenna can send/receive at. It might be possible to bodge wire an external antenna in to resolve that problem, not ideal, but... As for the display shift issue, looks like there is an offset error creeping in. Watching your video for the scrolling label, I notice that the "right" edge, when it wraps around from the right hand side of the screen to left hand side of the screen, it also shifts down a line. At a guess, one of the pointers to the display memory buffer is getting modified. One of the pointers will be being used by the DMA hardware on the ESP32 chip that pushes that memory out the 15 pins that are connected to the TFT display. The other pointer is the one used by the graphics library to make modifications to the display output. Once you have figured out which one is getting modified, you need to track down how it is getting modified. If your code is compiled and the processor is configured to run "big-endian", an 8 bit integer packed in after the pointer, if increased by a 16 bit operation, could be why the LSB of that pointer is getting changed. Changing the byte order of the code from big-endian to little-endian should change the behavior of the bug if this is the issue. I say change, because if this is the problem, something is working on an eight bit field using sixteen bit math, which is causing overflow, always a problem.

I suggest the ESP32 Wrover Kit, it doesnt have a tft display but has a custom library for display, it has a built on one and from use so far its quite good and im able to get up to 15-20 meters (up to 60 foot) in a clear space with a empty channel and the antennas facing eacholer but otherwise up to 10m through walls (30ft)

really cool, thanks!

Great vid. I just bought 2. I'm trying to find out How to connect a esp32 to it. I clicked on the github page but could work out how to make the connections. Can anyone here help. Thanks

Is there any compatibility involve in this product sir?

th-cam.com/video/0AVyvwv0agk/w-d-xo.html CYD 👍

what's "board type" in Ardruino IDE, sir? i can not connect esp32 2432s028 to my computer, i tried to select : esp32 dev module, esp32 wrom dev module...but it's still no working. please help me

Interesting video. Nice product for controlling projects. Are you planning on a video of how to design the graphics/buttons?

Very off topic here. do you know what is the connector type and pitch for the screen you used, IO connector ? I went to a couple shops and i get different answers.

I want to get one of these i just dont know if it is using the IL9341/ST7796 or XPT2046/GT911.

been looking for info for these sorts of esp borads found one like this on aliexpress just been trying to get info on them is not ez looking to use one as a gif player

Thanks for the information. I bought an earlier version before the ESP32 was popular and there was ZERO information on it. Even the manufacturer had deleted the information for it because they were trying to push the 32 versions. After that I just avoid these all in ones like the plague.

Macsbugs is Japanese, doofus.

TFT = thin-film transistor. It's the type of LCD display technology. en.wikipedia.org/wiki/TFT_LCD

th-cam.com/video/6JCLHIXXVus/w-d-xo.html Nice mod for audio.

What camera does this lens go to? Bought it for 10$ at a yard sale and I don’t know what it goes to but it looks cool

It's well worth the money imo. Swap the op amp and it bumps it up several notches.
