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

Can you use other free GPIO pins instead of GPIO9, GPIO10, GPIO11?

The board doesn't use USB-serial convertor, it uses the native USB of the ESP32-S2 chip.

You'd probably need to figure out which serial to use and have USB CDC on boot option selected.

It would be impossible to solve this for you since we lack the same software and hardware as you but we can compare with the board that works.

> 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?

A good choice for a small touchscreen that is compatible with the AM3359-SOM-EVB-IND is the 4.3-inch LCD with resistive touchscreen from Waveshare. This monitor has a resolution of 480x272 and comes with a USB touch control board, making it easy to connect to the AM3359-SOM-EVB-IND via USB port.

I did a test with another supplier of a board using WLED as well using the same settings on Ethernet and their board did not flash pixels. I was hoping it would have been the WLED software as it is a easier fix.

Can you guys look into it ?

I want to standardize my products using your board. So far I have over 100 boards and they all seem to give the same issue

Thank you

ESP32 / Serial Monitor with ESP32-S2-D...

Last post by dwd - May 16, 2024, 08:25:46 PM

I suspect this is a silly question, but I cannot get the Serial Monitor to work with this board. I can put it into boot-loader mode and upload a sketch, then RST and run it. However, when I RST the board so it runs, the Arduino IDE (Version 2.3.2) loses contact with the board and so cannot display anything.

What am I missing?

Minimal code to reproduce:

Code Select Expand

#define PERIOD  1000  //ms

void setup()
{
  Serial.begin(115200);
}

void loop ()
{
  Serial.println("Hello World!");
  delay (PERIOD);
}

ok, quindi non c'è modo di farlo funzionare? dovrei trovare due schede con revisione E?

Yes, better create a new thread.
