Posted on May 17, 2011 at 11:31Here's an addition: In the data sheet, I believe that there is an error with the calculation of CC. It is given as: CC[11..0] = ((PCLK/Tscl)-7)2 but I think that it should be CC[11..0] = (PCLK/(2xTscl)) - 7 I tested th...
Posted on May 17, 2011 at 11:31Hi All Can anyone explain the fast mode setting of the I2C controller in the STR91? The formula for setting the speed (CC[11..0] is in CCR and ECCR registers) is either PCLK/(2 x (CC[11..0] + 7)) - in slow mode up to 1...

Posted on May 17, 2011 at 09:49Hi Yes, this is correct, but it is up to you to first configure the Ethernet controller to correctly use the buffer descriptors. Regards Mark PS. Check out the following page for some demo code for the STR91 - with FTP...
