  4. [SOLVED] Can't make two OLED LCD's working together

    in Testing/Troubleshooting

    Posted

    Big thanks to TK again!

     

    I've tried the latest MBSeq V4 release (4.088 pre5) and both displays work smoothly when following TK's instructions above.

     

    This is how the new screensaver looks like:

    Attaching a picture of both OLEDs running along too.

     

    Can mod's add [sOLVED] to the title of this thread please?

     

    Thanks to everyone for ideas and support! This is really great community!

  6. Metronome audio out on STM32F4DISCOVERY?

    in Design Concepts

    Posted

    It came to me if there could be a metronome beeping out from audio output featured on STM32F4DISCOVERY?

     

    Setting two different beep frequencies and maybe length of the beep somewhere in the config or via bootloader but even predefined values would be perfect. Something like good old Atari ST Cubase.

     

    My MBSeq is not even finished but I was already scratching my head about how do I go with MIDI metronome. I'm not exactly thrilled by sacrificing one MIDI channel/voice, I would rather spend one audio channel on the mixer if I could choose. But of course I'll live happily wit MIDI metronome ;-)

     

    How do you guys run your metronome on MBSeq? Drum hits? Beeps? Something else?

  10. Screensaver for OLED displays?

    in MIOS programming (C)

    Posted · Edited by cube48

    Just for the start, I don't have functional OLED display (yet :fingerscrossed:), I'm no C programmer at all and my electro-technical knowledge is purely based on self-education.

     

    But now there is a hypothetical chance that TK might include support for 40x2 OLED displays from Raystar. And there are other OLED based projects coming. It is said that OLED's have usually shorter lifetime than classical LCD's. So it might be good to have some screensaving option. OK, 80.000 hours (forementioned Raystar specs) is over 9 years and nobody is leaving their gear on for that long but still ... it would be nice to run the same SEQ after some years without the need of LCD replacement.

     

    LXR by Sonic Potions has nice OLED too and screensaver is already implemented. I wonder how difficult it would be to borrow this stuff and implement it as an optional LCD setting?

     

    I.e.:

     

     

    set lcd_ss 1

     

     

    for activation and

     

     

    set lcd_ss 0

     

     

    for deactivation of the screensaver via the bootloader update app.

     

    Direct or HW dependent dynamic in-app system menu option would be of course more convenient but I don't know how relevant and feasible it would be for various apps and HW configurations.

     

    Beat me with pros/cons arguments, ideas etc. ;-)

     

    Cheers,

    One ribbon solution was just desperate idea of desperate man who has no idea about LCD hacking :-D

     

    I made a little progress ... sort of. I've changed the lcd_type to CLCD_DOG with bootloader update app and now the two displays show their content but only in first row. Content looks like smacked together, like two lines in one resulting in a bit chaotic stuff. Forcing the lcd_width/height has no effect doesn't help.

  17. SEQ4 Heidenreich Case Bulk 2014 / 2015

    in Bulk Orders

    Posted · Edited by cube48

    I have been thinking about offering a reduction to the current group buy (only).

     

    I think that, now people have confidence in Kristal's group buys, there would be no fear in ordering the panels at the same time (or there abouts) as the cases.

     

    So i am thinking something like this - 

     

     

    Anyone who is ordering from the current group buy may order a panel set at a reduced rate of GBP 100 for the set (plus shipping / pp charges at cost) with payments taken up until the point where Kristal receives the cases from Heidenreich.

    Although it is no quicker in machine time to make multiple panels, it is easier for me, logistically, to make them in groups, rather than bit by bit, so, the reduction in cost is intended to encourage ordering in groups.

    Anyone outside of the current group buy (as listed on the wiki) would be excluded from the offer - again encouragement to order as a group (sorry!).

    Does that sound like a reasonable plan?

     

    Julian, would this be valid for current batch? Is anybody else interested in getting the panels from Julian? 

    I'll definitely order from Julian/frontpanels.de but I don't have the back panel layout for MBHP_CORE_STM32F4 yet. All examples I saw seemed to be for 'older' board options. Have to search if there's any existing one already or create one when I have all IO's ready.

    I have the MBHP_CORE_STM32F4 ready with the board, no MIDI_IO, no CS yet (Wilba's CS board is on the way).

     

    Board is powered via USB, LCD power jumper is on 5V.

     

    The LCD's I try to connect are Raystar 40x2 OLED LCD's, the same

     

    When I connect them both, I get random characters/dots. If I connect only one of them, no matter which slot (J15A/B), they display the appropriate content (left/right display stuff). 

     

    I tried swapping displays and cables, all is fine, it's just that they don't run/initialize? together.

     

    When browsing the forum earlier, I have the vague feeling that somebody already had similar issue but I'm not able to find that thread again.

     

    Can somebody please give me a hint what to check? Thanks in advance.

  20. K-rAd's MB SEQV4 Progress?

    in Tips & Tricks

    Posted

    Congratz to the CS board! I see you've got the power supply ready. Gonna follow your progress as I expect to receive mine board too.

     

    Can I have a ribbon-cable-newbie question? How do you attach the cable to the connector? Is it just plug and push action or is there a special tool needed? On the connector pics elsewhere I saw little blades for each wire. Is there a specific ribbon wire distance that has to be appropriate for the connector? I've got some spare ribbon cables of various thickness but never used them with connectors so please bear with my dumb questions. I guess I'll find out when I receive the connectors but any hints or practical tips are welcome. Thanks.
