stm Posted April 3, 2015 Report Share Posted April 3, 2015 Hi, I looked at the "Benchy_Sump_LogicAnalyzer" example. If I understand it correctly, the serial input/output of the "Sump Blaze Logic Analyzer x8" symbol goes to the ZPUino, and on the ZPUino there runs a sketch that forwards the serial IO to the serial port of the Papilio DUO board. Is it necessary to forward the data through the ZPUino, or can the logic analyzer be used in a design that doesn't have one? I tried to add the logic analyzer to a simple design of my own and connected the tx and rx pins of the logic analyzer to the TXD and RXD pins of the Pailio DUO. Then I tried to connect to it with Logic Analyzer GUI, but that didn't work so far. I tried device types "Original SUMP device" and "Papilio Logic Analyzer", and when I click "Show device metadata" I see the serial LEDs blinking on the Papilio board, but then the "Device type" is cleared and nothing is retrieved. And for my understanding who the logic analyzer works: I looked at the VHDL implementation of the logic analyzer, and I can't find any actual logic in there, just lots of mappings and constant definitions. Is this really the whole implementation, or are there additional modules involved that I was not able to find? ThanksStephan Quote Link to comment Share on other sites More sharing options...
