Module esp32s3_hal::psram
source · Expand description
PSRAM “virtual peripheral” driver (ESP32-S2)
Overview
The PSRAM module provides support for accessing and controlling the
Pseudo Static Random Access Memory (PSRAM) on the ESP32-S2.
The PSRAM module enables users to interface with the PSRAM memory
present on the ESP32-S2 chip. PSRAM provides additional external memory
to supplement the internal memory of the ESP32-S2, allowing for increased
storage capacity and improved performance in certain applications.
The PSRAM module is accessed through a virtual address, defined as
PSRAM_VADDR. The starting virtual address for the PSRAM module is
0x3f500000. The PSRAM module size depends on the configuration specified
during the compilation process. The available PSRAM sizes are 2MB,
4MB, and 8MB.
