  5. Cascading Motofader NG module

    in Design Concepts

    Posted

    Hi

    Yes, MF_NG can be connected to a chain of 4 Modules. It workes by connecting the midi out port to the in port of the second module and so on. But befor you will have to connect it with your Computer and set the Modul 1-3 to the Link through mode with Mios Studio MF Tool. The last Module you will have to set as End Point Module.

    Also the Protocol has to be set Right. Take a read in the Manual of http://ucapps.de/midibox_ng_manual.html

    Best Regards

    Hi

    Yes right you can make your own J8/9.

    The SD card is used for the App. So you will have to load the Bootloader through the miniUSB connector. Then you will have to Download MIOS Studio to your PC/MAC and upload the MIOS system trough the microUSB to the controller. The Apps store the Controlling script on the SD card to save the space inside the chip...

    After that you need to Upload the App you whant to play with. Its like a PC where first is the bios then the OS like Windows or Linux and to do anything you will likely start a Program like an Texteditor that saves the file to a SD card... (Maybe)

    There is a walktrough tutorial on the ucapps site. Just click on the STM32 Core link.

    Best regards

    I think that you don't have to care about the measurement type because your DAW will send the Midi-Meterdata acording to your settings in the DAW it self. So if you have a Analog Needle Meter (generally called VU-Meter) you only have to convert the Midi Value in to the Voltage needed by your Needle.

    And if you like to have LEDs (digital Meter) you can just make a LED-Matrix. I have done that for me and created also supporting PCBs.

    Hi Fredric

    Well the MB_NG is a Software you can find in the Download section of ucapps.de.

    What you need to get that wonderfull software running is just the newest core. The STM32F407.

    If you are interessted in the board i made to attach 8 OLEDs seamless have a look to vlrlab.com. The dokumentation to the VLR_8oDisp is in work and will be available soon.

    To those displays from taobao you have to check. It seams to me that there is a missing Enable line. And the Driver is not the same (SSD1106 instead of SSD1306)

    Heh, nothing too fancy!<br />

    <br />

    I'm still learning PCB design, but one rule of thumb is that you shouldn't have breaks in your ground plane where signals run across. If they go over a slot the return current has to take the long way around. Probably complete overkill unless you're getting into the MHz range, but I figure why not if it can be done without too much fuss.<br />

    The blue is a keepout zone as measured from the Core r4,</p></blockquote>

    Also have a look to the outlines of a 8pin socket for the optocoupler IC2. It seams to me that the resistors arround it are to near.... And maybe C4 will be hard to mount as well.

  15. Faders technology and suppliers

    Well thats certanly possible but also not easy to do if you are looking for a Motorized Fader.

    I can imagine some Magnetical Cap thats been moved throu a Motor from the other side of the Frontplane but still it would be a mechanical part and i think its more reliable to directly take a Fader with mechanical tracking then. Especialy in thaughts of my 5 fingers mostly stabalizing an laying on top of the next two tracks to fade gently the one my pointing finger is moving... 😄

    But maybe for DJs with just a couple of Faders it would be more interessant, also because a DJ more or less does more Manualy than Automated.

    As far as i know thats not possible. Because a Midi Port is quite similar to a Serial Port, and there for sure its not possible.

    But most of the core run more than one Midi IN/OUT ports. The only core known by me that has just one is the old 8 bit PIC18Fxxxx.

    What OS are you working with?

    Hi

    The most advanced Fader builder is penny & gilles. Like this: http://www.cw-industrialgroup.com/Products/Faders/Linear-Motorised-Fader-PGFM3200.aspx

    But thats an expensive part. So the most used one is the Alps : http://www.alps.com/prod/info/E/HTML/Potentiometer/SlidePotentiometers/RSN1M/RSA0N11M9A0K.html

    They also produce pcb mountable ones.

    What you need to know is that midibox MF_NG is working with linear Faders.

    If you don't know about midibox have a look to ucapps.de and the shop selling the DIY kits midibox-shop.com

  21. LED Matrix

    in Testing/Troubleshooting

    Posted

    Hi FantomXR

    Thank you for the reply. I think i understand now. What happened is i connected the DOUT selection rows wrong. The first is the last and so on.

    Because i didn't have enough Headers laying around i tested just with two and didn't recognize my fault because i didn't see the last selection row glow when i tried to light up the first...

    Now because i got the Meters light up with Inverted=0 but not with Inverted=2 i was searching for a failure always with a inverse working circuit. 

    Have to redo my board or live with the inversed Matrix number...

    Best Regards

    Hi 

    Im currently Testing a 8x16 LED Matrix. I can't find out why all the rows are lighting up simultaneously. 

     

    the .NGC config is a simple test:

    RESET_HW

LCD "%C"
LCD "@(1:1:1)OLED1"

# Test D-OUT LEDmatrix board

# Matrix control by a Encoder connected to DIN Board on Pin D0/D1
ENC n=1 sr=1 pins=6:7 type=detented2


DOUT_MATRIX n=1  rows=16 inverted=0 inverted_row=0 sr_dout_sel1=1 sr_dout_r1=2  sr_dout_r2=3

EVENT_ENC id= 1  fwd_id=LED_MATRIX:1   type=CC chn= 1 cc= 24  lcd_pos=1:1:2 label="^std_enc" LED_MATRIX_PATTERN=1

LED_MATRIX_PATTERN n= 1  pos= 0  pattern=0000000000000000

LED_MATRIX_PATTERN n= 1  pos=11  pattern=1111111111110000
LED_MATRIX_PATTERN n= 1  pos=12  pattern=1111111111111000
LED_MATRIX_PATTERN n= 1  pos=13  pattern=1111111111111100
LED_MATRIX_PATTERN n= 1  pos=14  pattern=1111111111111110
LED_MATRIX_PATTERN n= 1  pos=15  pattern=1111111111111111

     

    My diagram of the circuit shows the DOUTs that are connected to LED boards where all the Cathodes are parallel and the Anodes connected directly to the DOUT 2-3 as the example on the top left corner shows.
