SPIM basic blocking

The sample demonstrates a basic functionality of the nrfx_spim driver operating in the blocking mode.

Requirements

The sample supports the following development kits:

Board	Support
nrf52dk_nrf52832	Yes
nrf52833dk_nrf52833	Yes
nrf52840dk_nrf52840	Yes
nrf5340dk_nrf5340	Yes
nrf54l15dk_nrf54l15	Yes
nrf9160dk_nrf9160	Yes

Overview

Application initializes the nrfx_spim driver and starts operating in the blocking mode. A specified message ( MSG_TO_SEND ) from m_tx_buffer is transmitted. When the transfer finishes, the received message is read from m_rx_buffer.

For more information, see SPIM driver - nrfx documentation.

Wiring

To run the sample correctly, connect pins as follows:

LOOPBACK_PIN_1A with LOOPBACK_PIN_1B.

Refer to pin definitions in common/nrfx_example.h.

You should monitor the output from the board to check if it is as expected.

Building and running

To run this sample, build it for the appropriate board and then flash it as per instructions in Building and running section.

Sample output

You should see the following output:

- "Starting nrfx_spim basic blocking example."

- "Message received: Nordic Semiconductor"
