7The sample supports the following development kits:
8
9| **Board** | **Support** |
10|---------------------|:-----------:|
11| nrf52dk_nrf52832 | Yes |
12| nrf52833dk_nrf52833 | Yes |
13| nrf52840dk_nrf52840 | Yes |

17## Overview
18
19Application initializes the nrfx_spim driver and starts operating in the blocking mode.
20A specified message ( @p MSG_TO_SEND ) from @p m_tx_buffer is transmitted.
21When the transfer finishes, the received message is read from @p m_rx_buffer.
22
23> For more information, see **SPIM driver - nrfx documentation**.
24
25## Wiring
26
27To run the sample correctly, connect pins as follows:
28* `LOOPBACK_PIN_1A` with `LOOPBACK_PIN_1B`.
29
30> Refer to pin definitions in `common/nrfx_example.h`.
31
32You should monitor the output from the board to check if it is as expected.
33
34## Building and running
35
36To run this sample, build it for the appropriate board and then flash it as per instructions in [Building and running](@ref building_and_running) section.
37
38## Sample output
39
40You should see the following output:
41```
42- "Starting nrfx_spim basic blocking example."
43- "Message received: Nordic Semiconductor"
44```
