  1. Display Connection with Mirrored Pinout

    in Testing/Troubleshooting

    Posted · Edited by novski

    I tryed to make a Board for the SCS. Actually a simple thing, but i got a strange failure i can't locate.

     

    I drawn a Schematic with Eagle witch Simply connects the Display to a Pinheader - 1:1. But now i noticed that the Connections at the Core to my Board are Mirrored. So Pin 1 has 5V and Pin 2 GND.

    I then Made single Connectors to the Connection J15A and Crossed every pin from upper row to lower and vice versa. That way the display runs, but still has some weird scrambled characters.

    So i Connected my already running 2x16 OLED and rebooted. As you can see in the Attachment there it shows the full words correctly. 

    I checked every pin twice and just can't understand that problem.

     

    Edited a more clear Photographic of the 2 connections.

     

    Thanks for any help...

  2. More Lcd and OLED display

    I have the Newheaven one and tested it already. You can see it here: link

    But i think without any reprograming the SCS is made for a 2x20 Display.

     

    I ordered that 2x20 type OLED from Newheaven last week and it should arrive tomorrow or so.

    As soon i have it working i will make you a Photo of it.

  5. Unable to load bootloader updater after MBNG

    Are you using the direct USB connection to the Core or a USB to Midi interface? - because there is a blacklist of interfaces that don't transmit sysex data correctly. Maybe its because of that... You can find it also in the Wiki area... Im also working with OSX over USB Core connection and don't have those experiences about a not responding MIOS Studio nor Core...

    @ Ilmenator: i think exactly same. This Midibox Project is huge and im always delighted to see people build stuff as big as a Lightning console or a Harrison Audio Desk. 

     

    @TK. to summarize the Question above, for SSD1306 Displays its possible to combine these three lines to one single connection...?

     

    RS         -DC                        (Coming from LPC17CoreModul  J15A)

    RW        -SDA      -D1           (Coming from LPC17CoreModul  J15A)

    E           -SCLK    -D0           (Coming from LPC17CoreModul J15A)

     

    And if so, how wold you name that single wire?

     

    Thanks a lot..

    I just realized that the shift register is connected to the same J28 as the additional lines 9-12 are. And thats what you mentioned in you second last post... - It enables the shift - register by activating more then 12 OLEDs in Bootloader... 

    sorry i got confused by the schematic of CLCD Displays and SSD1306...

    Hi, its me again...

    I have problems with the connection of the SSD1306 over an additional register.

    Am I ling right by connecting the CS lines with the Register Outputs described as E3-E10 on the schematic of LCDs?

    SDA,SCLK,DC are all connected together is written in the mbhp_lcd_ssd1306_multiple_mios32.pdf but are they also al connected to RW,E,RS  on the core together?

    That sounds a little bit strange to me...

    The Schematic of Multiple LCDs is showing the RW line as not "doted" so im now really confused.. http://ucapps.de/mbhp/mbhp_lcd_nx2x20_mios32.pdf

     

    VSS                       -VSS                     (Coming from LPC17CoreModul  J15A)

    VDD                      -VDD                     (Coming from LPC17CoreModul  J15A)

    RS                         -DC                        (Coming from LPC17CoreModul  J15A)

    RW                        -SDA      -D1           (Coming from LPC17CoreModul  J15A)

    E                           -SCLK    -D0           (Coming from LPC17CoreModul J15A)

    E3 - E10               - CS  on Displ 1-8   (Coming from Additional Register connected to J28)

     

    Can somebody verify that for me?

     

     

    The Second Question i have is to the Cap and Resistor. Is it necessary to place a Cap and a Resistor for each Display or is one enough for 8 Displays in a Row?

     

    I added a Snapshot of my Eagle schematic for better understanding...

     

    Thanks

  18. Replace fadercontrollers in Digidesign Control 24 with MBHP_MF_NG´s

    in MIDIbox HUIs

    Posted

    Hi Teig1

    Your lucky! With those Powersupplys you are in a good position. And all thoughts are correct. 

    Yes you will need the Core module, it will give you access to conect to your DAW over the USB connection witch doesn't need any drivers. It connects over Midi-over-USB. There will be no need of OSC for your proposal.

    You may need to use the HUI Protocol because of ProTools (if thats your DAW?)

     So your Setup wold be a LPC32_Core connected to MF_NG over one of the 4 Midi Ports (i think TK. suggested Midi3 somewhere in this forum, i just can't find it anymore...) anyhow its possible to connect over every Midi-port...

    After chaining all the MF_NG, return to the Input of the same Midi-port...

     

    I think to understand its easier with a schematic...

    Hi

    while waiting for the upcoming multi display informations :thumbsup: - i made a Standard Control Surface PCB. 

    I Ordered a Prototype Yesterday. It should reach me in a cuple of days.

    As soon its running i will publish it here. So SmashTV can sell them... (if he want to...) 

     

    Cheers!

  20. DIN with High Input ?

    in Parts Questions

    Posted · Edited by novski

    Hi again! Thanks for your advice.

    I went over the Schematics again and noticed in the Datasheet of 74165 that there is a inverted output on that part.

    So i think your solution is the best.

    To go sure i drawn it new. Is this corresponding with your thoughts?

    I attached a snapshot of the part and added the full schematics of my Encoder Board i want to build...

    I will test this on breadboard somewhere around new year.

    Thanks for the help!

    Edit: Better open that one in separate Window. Its to big for container...

  21. my first finished midibox

    in MIDIbox of the Week

    Hi John E. Finster

    Nice thoughts! Might be the smallest Midi-keyboard i have seen...

    It makes sense to Print the Front panel Layout 1:1 to hold it over the device before ordering.

    I never had a disadvantage with Schaefer. It always showed up to be my fault in the end...

    Happy new year!

    HI TK.

    There is no point i don't agree with your proposals. I didn't think about latencies yet.

    I don't have permission to Install any software on the Audio console. {For understanding of the host software:

    Its a 72 stereo channel real time mixer. It has 2ms latency from audio input to output. All running on a WinXP OS. Thanks to the Assembly language programed Audio processing, its really possible to even make in-ear monitoring for acts on stage with so low latencies.}

    Thats why my thought are always going back towards a independent working midi controller.

    Do you think it cold be possible to enhance latencies with a connection over the CAN bus with MBNet?

    Merry christmas!

    best regards

    Well thats exact the problem of my software. Its not possible to connect more than one midi in and out.

    Is there a other possability to connect a Display for each fader then with one LPC17 Core for 8 displays?

    Wold you sugest to rather connect al 4 fader modules to the first core and chain 3 more cores just for the displays?

    Best regards

    I have a general Question about the planed Router and Link option of NG and MF_NG.

    In the tutorial of its written that its possible to chain multiple MF_NG modules on one Core by setting the last as a end point in chain.

    Will it also be possible to chain several NG with one MF_NG "slave"?

    like this:

    DAW_Midi_OUT ->\

    LPC17_#1_Midi1_IN -> LPC17_#1_Midi2_OUT -> MF_NG_#1_Midi_IN -> MF_NG_#1_Midi_OUT -> LPC17_#1_Midi2_IN -> LPC17_#1_Midi1_OUT -->\

    LPC17_#2_Midi1_IN -> LPC17_#2_Midi2_OUT -> MF_NG_#2_Midi_IN -> MF_NG_#2_Midi_OUT -> LPC17_#2_Midi2_IN -> LPC17_#2_Midi1_OUT -->\

    LPC17_#3_Midi1_IN -> LPC17_#3_Midi2_OUT -> MF_NG_#3_Midi_IN -> MF_NG_#3_Midi_OUT -> LPC17_#3_Midi2_IN -> LPC17_#3_Midi1_OUT -->\

    LPC17_#4_Midi1_IN -> LPC17_#4_Midi2_OUT -> MF_NG_#4_Midi_IN -> MF_NG_#4_Midi_OUT -> LPC17_#4_Midi2_IN -> LPC17_#2_Midi1_OUT -->\

    DAW_Midi_IN.

    I wold like to get more displays and a flexible 8 fader module design...

    can't test it because i don't have the multiple LPC17s jet..

    best regards
