QSPI Example
This information applies to the nRF52840 SoC only.

The QSPI Example demonstrates the use of the QSPI peripheral with memory mounted on Development Kit. It uses the QSPI driver - legacy layer. The application initializes the QSPI peripheral, sends configuration commands to memory, erases the memory, writes data, reads data, and compares data.

You can find the source code and the project file of the example in the following folder: <InstallFolder>\examples\peripheral\qspi


Test the QSPI Example application by performing the following steps:

  1. Compile and program the application.
  2. Start a terminal emulator like PuTTY and connect to the used COM port with the following UART settings:
    • Baud rate: 115.200
    • 8 data bits
    • 1 stop bit
    • No parity
    • HW flow control: None
  3. Observe logs on a terminal.
  4. Additionaly, a logic analyzer can be used to trace the trasmission. Remember to set lower frequency when using additional tools, because additional wires can cause data distortion.
