2009-06-15 12:37:13     i2c driver for 533-Stamp

Hi all,

 

I have a question about i2c driver for 533-Stamp. Refering to the following Doc section: http://docs.blackfin.uclinux.org/doku.php?id=i2c I must use Soft TWI Interface and implemented i2c via GPIO's.

 

Is i2c implemented in any of uClinux releases or SVN branches for 533-Stamp? I want to run temperature meter for i2c. I guess I need something like device node. Am I right? Are any other ways to implemented i2c driver for my board?

 

I will be grateful for any suggestions and pieces of advice?

 

Lukasz

i dont really know what you mean by "is i2c implemented".  the soft-i2c bus driver doesnt care what board you're using.  the i2c pins are declared via the board resources -- just like the documentation already shows you.

Mike,

 

I meaned: is i2c driver implemented on any of distributions which are available in download section (uClinux releases or SVN branches)? I asked this question because I don't know do I have to compile the kernel or just download it from the web site.
