Hi Segmentation, I may suggest you these good tutorials : https://randomnerdtutorials.com/getting-started-with-esp32/ https://randomnerdtutorials.com/installing-the-esp32-board-in-arduino-ide-windows-instructions/ https://randomnerdtutorials.com/esp32-troubleshooting-guide/ "Is an external crystal r...

That results are too slow for my needs.
What is the name of your ESP32 Module? May you post the link, please.
Thank you.
Be safe! Stay at home!

Hi EUA,

I attached some images, copied the link and inserted it in the post. The next day, those images disappeared.
I will look for the correct way to post images. I can't adjust the dimensions of my photos on this forum.

Do you know the name (or code) of PSRAM? Suggest you to look for datasheets.

Where are my images that I posted last week?
I lost a lot of images.
What's wrong???
Can anyone explain what happened?

Hi ESP_Lvxinyue,
I found more issues! I will post as soon as possible.
Thanks

More Tests and suggestions: IMPORTANT - To get a connection to Pulseview, I used a button connecting the GPIO 15 to the ground. During boot, I press this button (as recommended by ESP_Sprite). My ESP32 Dev Kit board uses the ESP32-WROOM32 module. So I can use more pins. We know that some pins are r...

If let say enable GPIO7 for input 7, than ESP32 crash due SPI pins try to communicate with flash while occupied for input. You can select any GPIO pin that you want to use instead of -1 or 7. Also setting them -1 does not make that pin floating but low... I think the new ESP32-S2 will meet our need...

First Test - promising results! Congratulations EUA! I confess that I had a little trouble figuring out how to use the Logic analyzer. But I did!

Hi EUA,

I'm sorry for the lack of my feedback. But after my vacation, I am involved in a complex service to change a USB library used on a Linux system. As soon as possible I will do tests with your project. Thank You.

EUA,
Tomorrow I'm going on a vacation trip.
I'll be back on February 22.
As soon as possible, I will test your Logic Analyzer. I am very interested in doing that.
Thanks.
