Hello!

External flash memory often use SPI, and they are usually (always) act as the slave. However, the communication protocol on how to communicate with these varies between the different flash memories. You must find the communication protocol in the datasheet of your flash memory.

Thank You for pointing me to the right direction . Anyway in the nordic examples I've only a transfer method with an input / output array. As an SPI Slave I've an SPI Serial Flash Memory 16Mbit. What should I do if I want to write to a certain address of the SPI Memory ?

Hello,

I am not sure where you found that code. Are you sure you are not mixing SPI up with I2C/TWI? SPI does not use addresses like TWI. If you want to look into our SPI library, you should check out the examples found in the sdk:

SDK14.2.0\examples\peripheral\spi

You can try it together with the SPI slave example, located in:

SDK14.2.0\examples\peripheral\spis

Best regards,
