Hi,

I have this simple example of writing (to &H34) & reading (from &H74) from SPI addresses:

Code:
    Spi_array(1) = &H34
    Spi_array(2) = 0
    Reset Cs
       Spiout Spi_array(1) , 2
    Set Cs

    Spi_array(1) = &H74                                    
    Spi_array(2) = 0
    Reset Cs
      Spiin Spi_array_rx_status(1) , 2
    Set Cs


It happens that SPIOUT remembers the address where data was sent (Spi_array(1) = &H34) and with SPIIN command it reads data from this address and not from the address that I need to read (Spi_array(1) = &H74).

How to do that?

Best regards
Jure
