PSOC 4 BLE - AT25DF021A Flash SPI interface.

 Hey 

   

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.

   

 

   

Thanks.

I would suggest you to try: Creator -> Start Page -> Find example project and then select one of the SPI projects.

   

What went wrong, you already asked in this thread.
