majo go 0 Report post 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 0 Report post 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: Share this post Link to post Share on other sites

JSC 0 Report post 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. Share this post Link to post Share on other sites
