real time clock -- how to w NiosII ?

Anyone having a reference design or an idea on how to have a RTC as a NiosII peripheral ? The considered design shall use an EP1C3 + EPCS1SI8. Thanks! Cheers Franck P.

Hallo Franck,

There are two ways for using a RTC with the Nios. First you can use an external RTC with SPI, I2C, … interface or you can write or use an Verilog/VHDL module. In my current design I will use an external RTC (Epson RTC-8564) with the free I2C interface from opencores (http://www.opencores.org/).

Bye,
