towster2 Posted April 11, 2014 Report Share Posted April 11, 2014 Hi, I am new to the forum and new to MIDIbox. I built the LPC17, DOUT, and DIN modules this week and am trying to get them working properly with the tutorials and examples. Playing around with the SRIO Demo (trunk\apps\examples\srio) I found that the DIN module is working properly (when I toggle a button I can see confirmation in the MIOS terminal and on the connected LCD. However, I am unable to get any response out of the DOUT module; more specifically when I toggle the buttons the LEDs remain lit. I checked every output pin on the DOUT module with a multimeter and found that every pin is reading ~5V. Can someone please point me in the right direction as to why all my outputs are stuck high? I have checked the DOUT module pretty thoroughly for shorts and didn't find any. Thanks in advance! Quote Link to comment Share on other sites More sharing options...
towster2 Posted April 12, 2014 Author Report Share Posted April 12, 2014 Problem solved! I didn't realize that I had connected to the wrong 5 pins on the J1 DIL on the DOUT module. So effectively I had connected to SI rather than SO. Silly mistake, but I figured it out after staring at the schematic for a bit. After successfully testing the basic functions its time to start coding! Quote Link to comment Share on other sites More sharing options...
