CONFIG_D0WD_PSRAM_CLK_IO¶
PSRAM CLK IO number
Type: int
Help¶
The PSRAM CLOCK IO can be any unused GPIO, user can config it based on hardware design. If user use
1.8V flash and 1.8V psram, 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¶
17
Kconfig definition¶
