Re: [avr-gcc-list] SPI problem fixed

[Jack Valmadre]

I fixed the problem.  Looks like I had to read the incoming data before
transmitting again.
This code worked fine:

 SPDR = 0xAA; //sync byte
 while(!(SPSR & (1<<SPIF)));
 readBuf = SPDR;

 SPDR = 0x01; //getmodinfo
 while(!(SPSR & (1<<SPIF)));
 readBuf = SPDR;

Thanks anyway
Jack.
