i have two i.mx rt1050 connected via LPSPI, one as master the other as slave
Master DMA TX and slave DMA RX are both working.
next i want to exchange data with one transfer, simultanous exchange.
while master is clocking data to slave, the slave should send data back to the master.
in the examples from the sdk, the master first sends data, waits until done and then initiate the receiving.
i want to do this in one transfer.
is this possible? when yes, how? is there an example how to this?
