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,

     

    Thank you for clearing that up.

    The requested two bytes are the latest from MISO, is it right?

    That is correct. The first 3 bytes are op-code + 2 byte address, so the 4th byte (and onwards) on MISO will be the data you're interested in.

    The first 3 bytes from MISO can be ignored, is it correct?

     Yes.

     

    You read out 0x02, which is a jump instruction (see opcode in chapter 14.5), and the next two bytes would be the start address of the image, which I expect is 0x7800 when you read the next byte (default location of the usb bootloader). 

    Kind regards,

    Håkon
