SRIO Demo App

Recommended Posts

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.

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 by julienvoirin

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:
