Underskor Posted March 24, 2011 Report Posted March 24, 2011 I put the SRIO Demo app on my MIOS32 board, and whenever I touch a DIN pin (eg. J3:Vs OR J3:D0), I get an APP_DIN_NotifyToggle() 1 through 127. All 127 toggle between 0 and 1 with each touch. I may have misunderstood the purpose of the SRIO app but it says in the readme.txt: This application demonstrates the MIOS32_SRIO driver - DIN pins will be forwarded to DOUT pins - DIN pins send a MIDI message (Note Events) - DOUT pins controllable via Note Events - Encoders at SR 13/14 will send CC events The APP_DIN_NotifyToggle() functions aren't the note events the readme.txt mentions are they? I interpreted it to mean that each DIN would send an individual note event. Quote
julienvoirin Posted March 24, 2011 Report Posted March 24, 2011 (edited) you've got a short between SCLK and some near trace, maybe RCLK , or ground or 5V. Use "bip bip" mode multimeter and check independancies of the 6 signals (Si So RC SC 5V Gnd) i already had this problem some years ago I interpreted it to mean that each DIN would send an individual note event. True, you are right Edited March 24, 2011 by julienvoirin Quote
Underskor Posted March 25, 2011 Author Report Posted March 25, 2011 I just did what you said julienvoirin, this is what I got: J8:RC>J9:RC - connected J8:SC>J9:SC - connected J8:S0>J9:S1 - not connected J8:Vd>J9:Vd - connected J8:Vs>J9:Vs - connected On the DIN board, no J1 pins are connected. I don't understand what you mean by SCLK and RCLK though sorry, can't seem to find them on the PCB schematic. :pinch: Quote
julienvoirin Posted March 25, 2011 Report Posted March 25, 2011 you haven't understood what i wrote verify there isn't a short between Rc and Sc for example, or Vd and Sc, or Rc and Gnd, etc... SC = SCLK = Shift Clock ! Quote
Underskor Posted March 26, 2011 Author Report Posted March 26, 2011 Yup, I checked that and there were no shorts. All 6 signals are independent. I just thought I would post the J8:RC>J9:RC etc in case they were not supposed to short. :baby: Any other ideas? Quote
julienvoirin Posted March 26, 2011 Report Posted March 26, 2011 I had similar problems with shorts on DIN/DOUT modules, Core was alright Quote
Underskor Posted March 29, 2011 Author Report Posted March 29, 2011 Well it works, somehow! Unfortunately though I think I came home after a few drinks and poked around looking for shorts, so I don't remember exactly where it was. Thanks a lot for your help julienvoirin! Quote
