Hi I'm Suyo.
I want to use SPI of 16bit.
It writes 8Bit in 11-11 of SPI Core with Avalon interface(NiosII document).
Don't 16 bits correspond?
I think that only 8Bit supports because the type of the variable, too, is the char type of alt_u8.
SOPC Builder can set with 16 bits.
Because it is, it thinks that 16 bits can support.
How when wanting to write software at 16 bits, should it be?
I rewrote the driver of SPI.
It rewrote alt_u8 to alt_u16.
The error occurs when doing a rewritten header file include in the program.
There is a change point of the program contents hardly.
Why will the error occur?
Also, it confirmed whether or not to make a sample program actually and whether or not data was written.
Data isn't together written by 8 bits, 16 bits.
If using IOWR_ALTERA_AVALON_SPI_TXDATA(base, data), in case of 8 bits, the data should be written.
I confirmed Signal TapII but data isn't written.
Also,I attempted to access using the index but data wasn't written.
Is there a person who rewrote the driver of SPI to 16 bits?
Tell to me.
Please help me.
Best Regards,
Suyo
