spi_master_send_recv

[Milad]

Hello Folks, I want to send an array of two bytes and read six bytes back . Even though I am using bellow function but the Oscilloscope shows only 4 bytes of clock cycles. What am I missing ?

 spi_master_send_recv(SPI_MASTER_0, &tx_DARA0, 1, m_rx_data_spi,6);

Thank You

There may be more than four spi transactions there if those are the spi clock pulses in yellow. You might want to expand time scale so you can actually count pulses.

Don't know what blue trace signal is, but would suggest chip select (slave select) or a data line
