Hello,

I'm trying to receive data over spi, it consist out of an adres and the data.

example:

adres    data

0x01        0x01
0x01        0x02
0x01        0x03
0x01        ...
0x02        0x01
0x02        0x02
and so on
 

The code i use is this, I just have no idea how to read the 'data'

SPIS_Start(SPIS_SPIS_MODE_0 | SPIS_SPIS_MSB_FIRST);
while(1)
{
while((SPI_Status = SPIS_bReadStatus()) == 0); // wait for data to be received

bData = SPIS_bReadRxData();        // read the received data
   

switch ( bData){
    case 0x01:
        SPIS_SetupTxData(0xAA);
       
    break;
   
    case 0x02:
        if (data==0x01){
        enc_enable = 1;
        bool_start = 1;
        bool_stop = 0;       
        }
    else
        if(data==0x02){
        enc_enable = 0;
        bool_start = 0;
        bool_stop = 1;
        }

    break;
....

You have to read again with the same procedure as before:

    case 0x02:

while((SPI_Status = SPIS_bReadStatus()) == 0); // wait for data to be received

b2Data = SPIS_bReadRxData(); // read the second received data

        if (b2data==0x01){
enc_enable = 1;
bool_start = 1;
bool_stop = 0;
}
else
if(b2data==0x02){
enc_enable = 0;
bool_start = 0;
bool_stop = 1;
}

 ... and so on
