CONFIG_D2WD_PSRAM_CLK_IO¶
PSRAM CLK 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¶
9
