How should I configure the SPI (master) in order to communicate with a
slave that has a single bi-directional data line?
I guess I should tie the MISO and MOSI pins together at the HB. Then
what?
Should I enable or disable the SPI? Or should I maybe use the port D
Wired-OR Mode? I will also connect a PC to the SCI, then DWOM might be
no good since that also includes the RxD and TxD pins on port D...?
How should I configure the DDRD register as I tie MISO and MOSI
together?
Hope to hear from you very soon!
