I want to use WICED_SPI_1 interface to connect to a slave devcei. And I have some questions as below,
1. Does MISO and MOSI need to combine, then connect to slave's SDO pin?
2. Does software need to modify for 3-wire SPI communication?
The SDK version that I used is 2.4.1.
The board that I used is BCM9WCDPLUS114.
Wiced implements full duplex SPI. For half duplex SPI, MISO and MOSI lines needs to be connected and the WICED code needs to be modified to support half duplex mode.
