thank you for your numerous answers, i will try to get it right when i find the time, br ranger930

I would like to ask my question more specifically: How can I get Mios to start the program sequence with which all inputs ( analog and digital ) are read ( without having pressed a button or turned a potentiometer ) ? This is only necessary once after the program start. Where should I insert a program code? I have already searched the entire forum and the repository for help, but have found nothing. Please help me. I have a test setup with buttons, potentiometers and LEDs and the respective inputs are read after pressing a button or turning a potentiometer. Mfg ranger930

good evening everyone, after switching on my stm32f4 board, I would like to query all inputs ( DIN and AIN ) once under mios32 and send the values obtained once via midi in order to update my software ( Traktor ). Unfortunately I have no idea where I have to insert the necessary code e.g. in NG or midio128, querying buttons and pots already works so far, can someone please enlighten me, thanks for your support, greetings ranger930

Hi, is this working with midibox32 and stm32F4 core ? If yes, which config files need to be configured? I need to have round about 240 outputs for low current led's. Thank you for your help. Br ranger930 Update: i found the answer !

Hello mios friends, I have a midi controller based on a PIC18F452 and have programmed it in C. Is there a routine after starting the operating system that can read all inputs once and send the determined values as midi out (without turning a potentiometer or pressing a button)? br ranger930

Hi Thorsten, thanks for your answer. I have checked the PCB again and there are no multiplexers on the PCB , only ic's for digital inputs and outputs to drive LEDs. There are 13 analog pots there, all analog inputs of the pic are directly connected to 8 of these pots (all with a resistor AS pull up , or pull down, i don't know) the other pots are connected in the same way, but to the following signal pins of the pic: pin36 -pin40, rb3-rb7. Any ideas ? BR ranger930

Hi guys, i checked the inside of an old DJ controller called kdj500( Designed for Traktor DJ Software) and found 13 analog pots and fader, all connected directly to the pic controller 18f452. Within The desciption of pic based Core Here on ucapps Website i saw this: Analog sources (like pots) can be connected to this port (8 pots maximum). If multiplexed via AIN module, up to 64 pots can be scanned. Remember that All unused analog inputs must be conncted to ground. There are also some application which use this pin as digital in- or output (mostly described in REAMDE.txt or setup_*.asm file) is there in way that will work without additional ADC ic's? I cannot find More information and need your help. br ranger930

Very fast ! Thank You Thorsten !

Hi, is it possible to by some gm5 chips and some pcbs for that from a person in this forum ? I'm from germany. Please answer. Thank you for your help ranger930

Hi Rics, nice job ! i would like to see more detailed pictures. is your controller really bus powered with the all led's? how was your frontpanel printed ? kindly regards ranger930

Moin, ich möchte ein scratch wheel selber bauen: 6mm achse durch ein Kugellager, da irgendwie eine selbstgebaute encoderscheibe mit 360 Markierungen, evt. auch mehr( 60mm Durchmesser Scheibe ), 2 Lichtschranken, hat jemand schon so etwas selber gemacht ? reicht dann die Auflösung zum scratchen ? Ist die Auflösung besser, wenn ich einen Festplattenmotor benutze ? Wenn ich 2 DIN benutze, kann ich dann auch 14Bit Midi senden ? macht das überhaupt Sinn, oder muss die mechanische Auflösung höher sein ? Fragen über Fragen ! MfG ranger930

Moin, nochmal nachgedacht ! Stimmt natürlich ( Brett vor'm Kopp ! ) Danke MfG

Moin, kurze Frage: Wie schliesse ich ein Poti richtig am Analog Modul an damit die Drehrichtung stimmt ( Linksanschlag 0, Rechtsanschlag 255 )? Poti Anfang ? ( Vss oder VDD ) Poti Schleider an den Eingang des Moduls Poti Ende ? ( Vss oder VDD ) Kann es leider z.Z nicht probieren. Danke für die Hilfe MfG

hi, i like these buttons, has anyone a partnumber or manufator ? ranger930

mit oder ohne gummi ? das ist hier das sperma ! ( kleiner schertz ! ) MfG ranger930
