  2. Midiloop in my MIDIBox Seq V4

    in Testing/Troubleshooting

    Posted · Edited by audiomobster
    Trying to be more precise.

    Hi Peter,

    thank you for your quick response. I have just one Blofeld connected to SEQ MIDI out. No MIDI in. I guess that I have set some configuration in the SEQ to loop in the SEQ itself.

    Best regards

    Uli

    PS I'm hearing double notes so I assume a loop.

  10. stm32f4 com led blinking & lcd test issue

    in Testing/Troubleshooting

    Posted · Edited by audiomobster

    Hi folks,

    • What does a blinking of the com led mean on stm32f4?
    • When I load lcd interconnection test I get: Hex file contains invalid ranges for MIOS32 STM32!
    • The sequencer app loads fine, I just don't see anything on the display.

    I had the frontpanel accidentally connected to J10A, don't know if this makes an issue.

    Thanks and regards,

    Uli

  11. Program Bootloader into STM32F4 with openocd?

    in MIDIbox Tools & MIOS Studio

    Posted · Edited by audiomobster

    Hi there,

    I have no virtualized Windows so I am trying to flash the bootloader with openocd:

    openocd -f stm32f4discovery.cfg -c "program project.bin exit"

    I get following output:

    I guess I need an offset, but how large?

    Thanks and best regards,

    Uli

    The following seems to work:

    openocd -f stm32f4discovery.cfg -c "program project.bin exit 0x08000000"

    At least it doesn't throw an error.

    But it shows up as "Van Ooijen Technische Informatica". Isn't this weird?

  15. Dupont Crimp Connector

    in Bulk Orders

    Posted

    That's satifying, thanks. I was crimping some wires and even with a crimping tool I found it really sucks. As I plan to connect my MIDI ports and LEDs via cable, because otherwise I wouldn't have enough space on my backpanel, I would have to crimp about hundred pieces. These really save me some time and stress.

    Regards,

    Uli
