nRF24LU1+ spi program communication

Goodmorning,

while performing an SPI read with command 0x03, the nRF24 is sending data during command and address transmission. Is it right?

Thanks

  • Hi,

     

    while performing an SPI read with command 0x03, the nRF24 is sending data during command and address transmission. Is it right?

    If you are asking if the SPI read function is full duplex, yes, it is. You can get data shifted back on MISO while you're shifting data on MOSI. This is usually a one-command lag, meaning that the next transmission will return the data from the former command.

     

    Kind regards,
