hello i am new to spi, i am doing project on 3 wire spi interface. I am using 3 wire interface as Sclk,ssn,MOSI pins only , I am not using MISO pin .I am tested spi example code but does not works well.so can any one tell me that nrf52 dk -spi support 3 wire interface ( with out using MISO pin). The issue is the serial clock was not generates signals .For sending data the function "nrf_drv_spi_transfer(&spi, m_tx_buf, m_length, m_rx_buf, m_length) " was used.Every time ssn pin is low to send the data & it is set to high after sending the data.Here i am using AD9837 module as slave & it works on spi interface only.I am facing 1 issue i.e., as follows. Here the data i hexa decimal but in the example code the tx buffer must be character type
