CONFIG_D2WD_PSRAM_CS_IO

PSRAM CS IO number

Type: int

Help

User can config it based on hardware design. For ESP32-D2WD chip, the psram can only be 1.8V psram,
so this value can only be one of 6, 7, 8, 9, 10, 11, 16, 17.

Direct dependencies

ESP_SPIRAM && SOC_ESP32 && <choice: SoC/CPU/Configuration Selection>

(Includes any dependencies from ifs and menus.)

Default

10

Kconfig definition
