Hi Everyone,

This debug tool is useful in finding my coding error/s or helping figure out what the problem is:
github.com/me-no-dev/EspExceptionDecoder?tab=readme-ov-file

Also, I found this useful online resource for visualising your HTML and CSS code OR someone else’s:
.w3schools.com/html/tryit.asp?filename=tryhtml_intro
And this for learning HTML and CSS coding:
w3schools.com

I purchased your books to say THANK YOU and help keep you going 🙂
Kind Regards
Amos

Thanks for the reply back and for all the great projects. I ended up deleting some libraries and reloading them and now the sketch compiles but when I try to load it on the board I get a new error

Serial port COM6
A fatal error occurred: Could not open COM6, the port doesn’t exist
Error while setting serial port parameters: 9,600 N 8 1

I have th Ai Thinker Esp32 cam selected in the boards menu.
I think it is a driver problem or I need to update the ide.

There is a program already on the esp32 and I see it running in the serial monitor when I connect it an select the port so maybe it is not the driver I am just not sure really.

Thanks again I am going to keep working on it and maybe I will get lucky.

In reply to Farouk.

Hi.
That is a normal response of the ESP32 after a reset.
If you don’t get any other messages, the code should have been uploaded just fine.

Hi Sara
Can you please help
I have a problem with my ESP32 Board
I made a PC Board to mount it on
I am using a LoRa module with it
On bread board it works and transmits the signal
When I mount it on my PC board it shows the following problem

rst: 0x10 (RTCWDT_RTC_RESET), boot:0x33 (SPI_FAST_FLASH_BOOT)
flash read err, 1000
ets_main.c 371
ets Jun 8 2016 00:22:57

You have addressed this problem with a previous query I followed that solution
It still does not work
Is there something else that could cause this
I have checked my PC board over and over for any errors

Kind Regards

In reply to Sara Santos. Hey actually I'm getting this error message whenever I upload the code then press the boot button while connecting message appears: Download mode successfully detected, but getting no sync reply: The serial TX path seems to be down.
