lpspi_interrupt_b2b_transfer_slave#
Overview#
The lpspi_interrupt_b2b_transfer example shows how to use LPSPI driver in interrupt way.
In this example, we need two boards, one board used as LPSPI master and another board used as LPSPI slave. The file ‘lpspi_interrupt_b2b_transfer_slave.c’ includes the LPSPI slave code. This example uses the transactional API in LPSPI driver. The LPSPI master send/received data to/from LPSPI slave using interrupt (the LPSPI slave is using interrupt to receive/send the data).
Running the demo#
When the demo runs successfully, you will see output in the terminal like this:
