ESP32 Forum

Good afternoon,

I have a ESP32-S3-WROOM1 module which includes an internal SPI 2Mo RAM.
I have started a new project under Eclipse but I don't know how to declare the 2Mo RAM
in my project.

Moreover, I don't know how to use these 2mo Ram in the firmware.
Is it used automatically by the chip when I declare soem variables or use the new instruction ?

Thank you for your help,
My goal is to use the 2Mo RAM.

Best regards,

Thomas TRUILHE

I have found this link https://docs.espressif.com/projects/esp ... M%20memory.

Do y ou think it can be used To use embedded RAM or thé WROOM module ?

You probably want the ESP32-S3-specific version of that page: https://docs.espressif.com/projects/esp ... l-ram.html

But yes, that should describe all you need to know to use SPI RAM under ESP-IDF.
