lpspi_interrupt_b2b_slave
Overview
The lpspi_interrupt_b2b 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_slave.c’ includes the LPSPI slave code. This example does not use the transactional API in LPSPI driver. LPSPI master send/received data to/from LPSPI slave in interrupt. (LPSPI Slave using interrupt to receive/send the data)
Running the demo
When the demo runs successfully, the log would be seen in the terminal window:
LPSPI interrupt board to board (b2b) slave example.
Slave start to receive data...
LPSPI transfer all data matched!
Slave received:
