ESP32 / Re: ESP-POE having problems wi...

I think it is some influence between grounds or ground loops. It seems to me it is power related.

How do you power the ESP32-POE? Is it powered from the same source as the LED strip? If not - did you measure if there is voltage difference between the two grounds? Can you give me a diagram or sketch or schematic on how the hardware connection and power supplies and grounds are connected?

There should be COM port after the reset, that is the whole point of USB CDC on boot. I see it listed as COM after reset. If settings are set as I've set them here, then probably something didn't update properly.

Try restarting the Arduino IDE. Maybe try another USB port and also try using the generic board entry instead of the Olimex one, it is called "ESP32S2 dev module". Then set like this:

Also this seems like quite often encountered problem for WLED users. Did you check for other users of WLED that reported similar problem like:

> I did a test with another supplier of a board using WLED as well using the same settings

Which other board exactly did you use and where did you connect the LED on it?

Hi
the software is open source. You can install it here https://install.wled.me/
You select using the ESP32-POE as the ethernet device which is your product.

The code for this project is also open source and can be downloaded from  GIT

Code Select Expand

// ESP32-POE
  {
     0,                   // eth_address,
    12,                   // eth_power,
    23,                   // eth_mdc,
    18,                   // eth_mdio,
    ETH_PHY_LAN8720,      // eth_type,
    ETH_CLOCK_GPIO17_OUT  // eth_clk_mode
  },
Are the settings for your board. All other boards are specified and then they run though the same software chain to the output.

the link to the GIT Code is
https://github.com/Aircoookie/

This is the similar board that we used the same code ver 14.3 to test with. Granted it does not have POE.
https://quinled.info/quinled-dig-octa-brainboard-32-8l/
 
He used GPIO 0 for the output to the LEDS.
There is a whole process I went through to determine where I felt the problem was.




1. Installed WLED and ran the internal patterns - no flashing
2. Ran Artnet though Ethernet port - Flashing
3. Ran Artnet through Wifi - No Flashing
4. Added Level Converter - still Flashing
5. Added 1000uf capacitor after the BUC converter near to the ESP - still flashing
6. tried 4 different versions of WLED including the latest BETA versions.
7. Changed Power Supply with different brand - Circuit draws 1.4A we tried both 6A and 4A
8. Tried different GPIO, 16, 15 and 32

please dont get me wrong, I love your board.

Flashing defined:-
The easiest way to see it is to use a program that sends Artnet data like a free one JINX or Madrix.

Then on Blackout leave it for up to 10 minutes and there will be random flashes, sometimes all 100 pixels and other time only a few. Sometimes they are 3-4 minutes apart and other times within 1 minute.

I only use 100 Pixels per controller for this project. They are WS2815 12v.
I have tried with and without inline resistors on the data line

The fact that the LEDs work perfectly by either using the Internal Patterns and ARTNET using the Wifi Connection points towards 2 areas.

1. There is a problem with the WLED code or
2. There is compatibility issue between WLED and the ESP-POE.

By getting a similar product that works through the same code chain , helps me to eliminate the WLED code (My personal feel)

If I have missed anything that you can suggest. I am open to trying it out. I do not believe it is between the port and the LEDs as in 2 different ways it works perfectly. Having tested the issue it with a competing board and it works, narrows down the issue to your Wonderful board. 

Thank you

Thanks for the suggestions. Installing "developer Arduino for ESP32. 3.0.0-rc3" helped a little, as the "USB CDC on boot" option now appears (and is enabled).

Unfortunately, I still see the problem. In boot-loader mode, I see two ports (COM3 & COM4 - COM3 looks like the one that works), and I can upload a sketch. However, when I reset to run mode, the ports disappear, and so the serial monitor does not work. "Not connected. Select a board and a port to connect automatically." But, the Port menu option is disabled (grey).

I have tried 2 boards, different cables and different USB sockets  I guess there is some other magic missing!

You are right, looking at the source code that is also published, and more specifically in OLIMEX.h there is list of all commands and corresponding code and at the bottom there is:

#define SET_ADDRESS 0xF0

I will be fixing the manuals, sorry for your troubles but thanks for the effort and contribution.

Your code works fine here: https://imgur.com/a/d9JChM2

These are the settings I use: https://imgur.com/Apk76Z6

I use latest developer Arduino for ESP32. 3.0.0-rc3
