Re: [ECOS] at91sam7 spi test code

["Frank Wu" <qiongwu23@gmail.com>]

Hi Andrew,

It is very easy to get a SPI eeprom sample chip on line to be the SPI device.
Maybe my question is not addressed clearly. What I want is how to use
SPI driver in eCos porting to at91sam7 evaluation board (I have the
board). Something like,
1) Initialize the spi port
2) write
3) read
4) use in interrupt/pulling mode

Thanks

Frank
