Hi. I have some issue when I access the Digital Port in input mode using a MokuGo with the latest firmware release (580), while everything is fine in output mode. To understand better, I wrote this trivial VHDL program, which simply replicates InputC(0) into OutputC(9). To feed the input I have generated a clock into OutputC(15), and externally I have wired OutputC(15) to InputC(0). VHDL\_code.png shows the code. The MIM setup is shown in Setup\_1.png and Setup\_2.png (the scope in slot 1 is only a place holder) The logic analizer data can be seen in Image\_1.png and Image\_2.png. ![VHDL_code](https://canada1.discourse-cdn.com/flex035/uploads/liquidinstruments/original/1X/a72819fdaa4b3755d096c3df39264ffbd0624fe8.png) ![Setup_1](https://canada1.discourse-cdn.com/flex035/uploads/liquidinstruments/original/1X/b52d9a0fb8ef6b2e9173f02556d2c00b5ecca4f1.png) ![Setup_2](https://canada1.discourse-cdn.com/flex035/uploads/liquidinstruments/original/1X/df5b0a3c05656af0b3d38131b7fbdc353a43785d.png) ![Image_1](https://canada1.discourse-cdn.com/flex035/uploads/liquidinstruments/original/1X/60d4a5a1c92d919cd2c874312ee194ba81b9b080.png) ![Image_2](https://canada1.discourse-cdn.com/flex035/uploads/liquidinstruments/original/1X/985f67ab9c867237d57d9a30af36b0e2ccd58ae1.png) =\> OutputC(9) seem totally uncorrelated to InputC(0). Where is my fault ?
