You Sir Rock! Thanks a ton. :)

Looking for help with NGC file (bank routing and layout)
GuitarNut67 replied to GuitarNut67's topic in MIDIbox NG
I found the "set_active" feature with Multibnk.NGR & .NGC examples. ...still confused but trying to work through it. -
The NG manual page: http://www.ucapps.de/midibox_ng_manual_ngc.html Has a bad link under the Banks category. "Please note that it's also possible to assign only a subset of controllers to banks, and to use the remaining hardware elements for dedicated functions outside the bank: Link to a configuration example." I could really use that example in my current project. Thanks GuitarNut

I'm trying to build a Midibox NG interface for a guitar preamp. I have built the hardware consisting of 12 encoders, 3 toggle switches, 1 LCD, a few LEDS on a DOUT. I have 2 different DEFAULT.NGC files (representing Mode 1 & 2 Below) with Switch 2 banking encoders 1-8. The hardware is tested and working for each NGC file. :smile: I need to combine the code from both NGC files and add encoders 9-12 with banks of their own, responding independently of banks 1&2. (Is this possible?) I also intend to add Mode 3 to Switch 1 soon. This is how I want it to work: Switch 1 : Mode 1 => Switch 2 (banks 1 & 2 for encoders 1-8), Switch 3 (banks 3,4,5 for encoders 9-12) Switch 1 : Mode 2 => Switch 2 (banks 6 & 7 for encoders 1-8), Switch 3 (banks 8,9,10 for encoders 9-12) Switch 1 : Mode 3 => Switch 2 (banks 11 & 12 for encoders 1-8), Switch 3 (banks 13,14,15 for encoders 9-12) But I am confused on how to accomplish this. Should I use radio buttons, Meta events, can banks be inside other banks? Any help would be very appreciated. Thanks GuitarNut

OK, Finally completed a second Breakout board, this time it worked! :smile: Must have messed it up while building it. Please disregard the graphic earlier in the thread. I incorrectly labeled the connector. I wouldn't want to confuse anyone. If TK could delete this thread that would be OK with me.

Ok, Good news I ordered more STM32F4 boards and they all react the same with my Core breakout board. I didn't fry the processor board. :) Bad news, Still have a non-functioning SD interface. I guess I need to remove the current SD Connector and start over.

Ok, I tried a 2 gig SD card with no improvement. :no: Triple checked the solder connections on the board and SD card socket these seem fine and, I was incorrect in my earlier post (I confused the orientation of J16 making me think I had a short between RC1 & RC2 it was actually Vs & Vs). Do you think I may have damaged the STM32F4 board by powering it up with an incorrectly oriented 74HCT541 chip? I'm considering purchasing another STM32F4 for comparison. Thanks

Thank you, for the quick response. Yes, I will try a 4GB card to see if that makes it happy. I did notice that the same errors occur when there is no SD card in the slot. I removed the STM32F4 board from the socket and made a continuity test for all pins on the SD card and where they arrive at J16. I notice some crossed lines in my test, I'm including a drawing showing my results. In my continuity test, pin 9 & 6 of the SD card bridge both RC1 & RC2, while pin 3 joins them at RC1 of J16. Is this a proper connection? Thanks

I may have messed up my STM32F4 board. I accidentally plugged the 74HCT541 in backwards while trying to power it up for the first time. No lights came on. I replaced both chips on the core module and got the boot loader and LCD working. I installed Midibox NG 1.032 but my SD card fails. :( From MIOS Studio 2.4.6 (here are the details) [319531.507] sdcard [319531.499] SD Card Informations [319531.500] ==================== [319531.500] ERROR: Reading CID failed with status -256!

I tried two 8 gig sd cards (one Ultra) format FAT 32. ========================== I checked continuity between the solder pads of the sd card before assembly nothing seemed to be causing a short circuit. Is there a way to trouble shoot SDCard or Connector and the STM32F4 board ? I couldn't locate error status codes while searching the forum. Thanks, A confused GuitarNut

Yes, any supplier information available?
