I want to send data to some shift registers using the hspi - sdo pin C.1 on a 20X2 chip, I dont care about the sdi input B.5.
Reading the manual is a rather vague about the subject, saying the sdi port has to be in the correct state in order to send data out, without actually saying what state is needed; the only example is for an EEPROM read\write.
Can anyone tell me what I need to do with the sdi input, do I just ground it or pull it high, or can I ignore it and use it for other purposes.
Cheers
