From: Makarand Purohit on 24 Apr 2008 08:35 Hi, I am trying to read the data from a sensor(ADIS16006 - SPI output). I have a BF533 EZ kit lite board(older version without P6). I have somehow managed to get the connections made from the expansion interface. As per my limited knowledge I need to configure BF533 as master and the sensor device as slave to read the data. The only example with VDSP++ which uses SPI is the Audio talkthrough (which is only to configure the audio codec). Please help me with the programming the various registers properly in general and SPI_FLG in particular. Thanks, Makarand Purohit

Behold: the SPI programming is explained in the very detail at the "Blackfin BF533 hardware manual" page 437. Vladimir Vassilevsky DSP and Mixed Signal Design Consultant http://www.abvolt.com |
