PSOC 4 BLE - AT25DF021A Flash SPI interface.
I am trying to interface AT25DF021A flash with PSOC 4 ble using SPI interface.
CS pin low then sending an opcode to flash and expecting 4 bytes from it. Then connecting CS pin back to 1.
Please can please send me some sample code snippet to read and write to SPI bus.
