  1. thank you for already completing the one for dipCoreF4 also
  2. to insert image from dropbox url: replace dl=1 by raw=1 ;) Best regards Bruno
  3. Andy, I will try the 6N137(CMOS output) too very soon...
  4. Andy will confirm but yes, it's a voltage divider.
  5. I made a short video for dipCoreF4 new second USB Host port. I made a dirty MIDI class which will deserve to be cleaned and integrated better in MIOS32 but it works. I tried to use the OTG_HS dedicated DMA but it's maybe a bit complicated for me, I will need help for that part. (edit) maybe DMA don't work with BULK transfer type !? So here first regular USB(OTG_FS) is connected to my laptop and MIOS Studio. Then I'm connecting 2 different MIDI devices to the second USB(OTG_HS in FS and Host mode), a waldorf streichfett and a Korg PadKontrol. Then I try Mouse and Keyboard for HID demonstration. Hope you like this new feature cause USB is a tricky thing to code!
  6. Hi @darkkat It's a bit more complicated than that ;) We've got standardised ports we use with standardized modules(everything is in ucapps pages). There's already alternatives to the discovery or the lpc too. Latigid/Andy already designed a new core based on waveshare 407(stm32f407) which fits into the new SeqV4+. the wCore. Like I said everything is somewhere you just have to take the time to dig all that. More than that, you're not the first to complain about the size of the cores, then I spent some time to design a new one, a compact one, which will perhaps bring the answer, I hope(worked a lot on it), the dipCoreF4 is already prototyped and based on a stm32f405. TK has produced a lot, people have added a lot to his work too. It's a gigantic knowledge base dedicated to MIDI, electronic and music. I can admit that it can take a certain time to integrate, assimilate the essential. but take your time so that you can bring your stone to the building too. Should be great! Best regards Bruno
  7. What's the difference? those Character lcds are already standard. ...But of course you can wait for TK's answer, he follows this thread very closely... Best Bruno
  8. http://avtanski.net/projects/lcd/ ("character lcd simulator" on google ;)
  9. Welcome @darkkat Everything you need to start is available somewhere, first there's uCapps, for more information there's a dokuwiki. if you want to dig into the code there's a subversion repo. Most important is that people here are kind and I'm sure someone will share with you everything about the sampler! Welcome again! Bruno
  10. Ahah :) You did a module from this machine, good idea, this gear is a 'must have' for an electronic music studio. I've got a Psycho SY-1M, that I suppose you know
  11. Even with all the red stripes this is beautiful, there's a lot of work in this, what it is?
  12. For me, THEY provide a DRC we have to follow then they HAVE to respect it too. Or they can not provide the service. But I never got any isolation issue with OP, and this is not the problem this time too, unfortunately. Except plated slot error, everything else seems fine for the moment included USB which has sensitive traces. First I was disappointed but I quickly found a workaround and they are usable for dev, that's fine. :)
  13. Eurocircuit made the OLRE16(green version) which was absolutely perfect, very precise, the most beautiful board I even made. I try to work with them, but they are too much expensive for Prototype quantity, then I used OP for that part. Grrr And I'd got a lot of problems with Seeed production with the exactly same design same rules of the OLRE16(black version on pictures).
  14. Yes for sure. But I hope our fab works in white room ;) dipCoreF4 is a tiny board, 20mil is just impossible in that case. I know Eurocircuit will do it perfect, they are expensive but the board size is small. Price is good enough from 25 pieces. I will check that later and PCBA too... Thanks Andy
  15. What "isolate" means? Clearance? And what is reasonable? I use 5mil clearance for dipcoreF4.
  16. Yes I know but I took that risk, cause I already did it by the past and it was working. But to avoid any risk I will make slot for each "combo holes" on next run...
  17. Hi Peter, Great!! But don't minimize your own work! :) What about Portuguese stuff ? ;) Have a good day Bruno
  18. This is exactly what happens, pad shape on internal layer are not extended like bottom and top are, then larger plated slot merged GND and VBUS on internal layer. The only way to avoid it and keep the slot is to add copper with the extended pad shape like this: Now I know it!!!
  19. Then finally, I've got 3 issue. - Because of a plated Slot VBUS is connected to GROUND on the dipCoreF4. - Because of a plated slot DC-IN is connected to GROUND on the External power module. - From the same brand and range I put a RJ45(8p6c) connector model instead of a RJ11(6p6c) on the MCAN Module. But I found a workaround for first and second issue. For last, MCAN module doesn't matter for the moment... So I decide to not refab it, they are working, enough for our tests, I prefer to keep the money refund for another and double checked run or something else. I will change fab too for next run. They sent me a dipBoard with copper totally scratched and cut under soldermask then there was no visual check, no quality control. That's definitively not good Beta testers, I will send you the boards on Monday... Hope you will understand, I will provide you some thin cable and heat shrink tubing I used for dipCoreF4 workaround. Next run will be perfect and ready to run your application cleanly. I'm currently finishing the MIOS32 modification for this Core, I will share pictures and example in the next days. Best Bruno
  20. Osh-Park but it's the first time, their first mistake and we are far from first order... communication is good, they answered me in the hour. Dan already refund me some as a gift just for the time spent on soldering and wasted components. Now they are looking for the reason of the error, they are checking their production line. They need to understand before fab it again. This is fine for me, I've got one working I can check everything and maybe leave beta version on next fab directly. I suppose it can happen to the best too. Nobody's perfect.
