Hi Dialog,
As we know, DA1469x can access QSPI-RAM chip through its Quad SPI RAM/FLASH Controller.
Is possible for DA14683 to access QSPI-RAM chip (such as APS6404L) through its Quad SPI controller ?
谢谢,Peter

Hi Peter Luo,
This is not possible in DA1468x product family, because there isn’t a Quad SPI RAM/FLASH Controller, as in DA1469x.
In case of DA1469x, please check dg_configUSE_HW_QSPI2 macro definition. You should set to 1 in the custo_config_xxxx.h to add PSRAM support. In the 12.2 of theAN-B-074: DA1469x emWin Graphic Library and GUIyou will find detailed step for how to connect an external QSPI RAM,
