I2C clock frequency

[cjgarcia]

Hello,

Is it possible to change the I2C clock?. I believe that it is 400 KHz, and I would like to have less then 100 KHz.

Best regards,

Carlos.

Hello,

The Zynq Technical Reference Manual http://www.xilinx.com/support/documenta ... 00-TRM.pdf p.611 explains that the I2C clock is generated from the CPU clock using 2 divisors :



You can try to set the value of the divisors by writing the registers defined here : http://www.xilinx.com/support/documenta ... er.Details (p. 1386).
