LPSPI SEND question.

hi.

i would like to use the send function of LPSPI0.

(LPSPI_DRV_MasterTransferBlocking)

but now there is no signal.(oscilloscope)

Attachment 1. H/W circuit diagram.

Attachment 2. config setting.

Attachment 3. code init.

i have a question here.

Is transmisson possible even with only LPSPI0_OUT?

Or should I connect another pin? (ex. LPSPI0_PCS1)

only the send function is needed.

what are the requirements for that feature?

(i using 32K146)

thank you.

Re: LPSPI SEND question.

As the Master, you should at least initialize the Serial Clock pin.

Best Regards,
Robin
