int alt_avalon_spi_command(alt_u32 base, alt_u32 slave,

alt_u32 write_length, const alt_u8* wdata, alt_u32 read_length,

alt_u8* read_data, alt_u32 flags)

1) where can i find what value i should put for alt_u32 slave?

2) what value should i put for flag?

3) if i m going to just send the data, in mosi mode, what value should i put for read_length and read_data?

4) do you have an example demostrating how to use this command ?

May You see source code of "altera_avalon_spi.c" ?

If you can do it you can find out function alt_avalon_spi_command.

And see all information about this function and its variables.

I recommend you read manual about SPI in SOPC builder
