Hello Comunity!

 

 

After two inconclusive disturbing days of reading in many different pdfs, trying to realize a I²C connection i have to ask you about this.

 

I have a ADZS-BF561-EZLITE Board and i want to use the PF0 and PF1 pins from the SPI Interface to realize a TWI (I²C) connection to different TWI-slaves.

 

 

Am i right with the assumption that the best way to do this is to use the ADI_TWI_PSEUDO DEVICE DRIVER installed with VirtualDSP++?

 

And am i right with my other assumption that i have to use the pseudo device driver because of the missing TWI hardware support?

 

 

I tryed to configure the pseudo TWI like it is described in it's pdf documentation without success. It seems like the used timers and registers are named for another Blackfin (not BF561) and i wasn't able to find a timer overview for the BF561 in all thous pdfs.

 

I don't want to ask you guys doing my work, but maybe someone can give me a hint to some usefull tutorial or some more hidden documentation

 

 

Thanks and regards!
