majo go Posted March 22, 2018 Report Share Posted March 22, 2018 Hallo, I have simple problem with the output of signal in the schematic of Xilinx. I've started Xilinx from the simple default Blink file and wand to connect the clk_96Mhz from the ZPUino Soft Processor to D12 of the Pinout. Everything I tried is going to be an error. Can someone explain me how to do this; ore have a good “tutorial” which is using the Papilio. I want to do this in the schematics to understand how to do this.

Jack Gassett Posted March 26, 2018 Report Share Posted March 26, 2018 If you try to connect the 96Mhz clock to an external pin you are not going to see anything on a LED attached to that pin, it is going to be too fast. You want to slow down the clock to something you can see. Please take a look under the symbols area for the Building_Blocks there are pre-made tools to help connect to a 32Mhz clock (which is the default clock for Papilio) and slow the clock down. You can do something like this: Quote Link to comment Share on other sites More sharing options...

JSC Posted June 28, 2018 Report Share Posted June 28, 2018 Hello, but what if I just want to output a square higher than 32 MHz? I don't want to see a LED blinking, just monitoring on an oscilloscope. In the symbols area "Clocks" is for example a symbol that generates a clock with 960 MHz.
