1.20 SST26 SQI Flash Driver - Flash read write in SPI mode
This example application shows how to use the SST26 driver to perform block operations on the On-Board SST26 Flash memory in SPI mode.
Description
This application uses the SST26 driver to Erase/Write/Read on the On-Board SST26 Flash memory using the SQI peripheral library configured in SPI mode. The application consists of APP_SST26_Tasks() which is called through SYS_Tasks() routine.
