Error Update!!! --------------- I don´t need new Program... one little complication is still working. One Button in the Matrix makes a double note, and the last open Shift Register (Shift Register 11) is not reading. I have 48 (44) Encoder at Shift Regitser 1-11 and the Button Matrices at 13-16... I replaced the 4 new Encoders at SR11 with 8 Buttons, but it doesn´t work... finish UPDATE......! ALL BUTTONS and ALL FADERS, POTIS are alright. the last and the least 4 Encoders doesn´t want work. I replaced the 4 encoders with 8 Buttons and filled in, the code, into the program. but it doesn´t work... the 4 encoders, that i have planned before, are working fine.. In the program are 48 Encoders placed, but 44 Encoders are working... What´s the Problem ??? thanks...and greets...

i become a f... o.. with this. :sick: Now i build in, 4 Encoder more. So, i have the Shift Register 1-12 (DINX4_1 - DINX4_3) complete connected with Encoder. I changed any point in the Program... #define NUM_ENCODERS 48 #define NUM_MATRICES 2 #define FIRST_ENC_DIN_SR 1 // DINs of first 16x16 matrix (counted from 1) #define DIN_16x16_L0 13 #define DIN_16x16_R0 14 // DINs of second 16x16 matrix (counted from 1) #define DIN_16x16_L1 15 #define DIN_16x16_R1 16 // DOUTs of both matrices #define DOUT_16x16_L 1 #define DOUT_16x16_R 2 Now the new last 4 Encoders doesn´t work but the 4 Encoder that i connected before... :question: What a hell!? and Now the Matrices doesn´t work well. i don´t give up!! :hairy: I will try to change the parameters of the matrices and take look a the encoder connections, and send after a new try some feedback.....

Can someone help ?? The Program already exists in the Repository of Mios32/trunk/apps/quickies/csc , but it has to be updated... Greets CSC

I need a new program for my Midi Project CSC.... a preprogrammed sample is already in the repository in the apps/quickies/csc folder. The Based Version was created with 40 Enocders, 128 Pots, an 2 16x16 Matrices at 4x AINX4 Modules, 4x DINX4 Modules, 1x DOUTX4 Module at a Core32 Board over USB to the XP PC. The new Version has 4 Encoders more. I have also tried to change the details in the program, but it doesn´t work. Can someone write a new program or an update for this Controller? It worked fine with 40 Enoder and all other parts till i build in the 4 Encoders in. Thanks a lot for help. Greets Chris

Background from this topic was a small answer for members who want to get some informations about the cable length, if they only find the answer, that the cable length... has to be short as possible. and for sure, this not only the point for the maximum cable length factor but better than searching hours in the Web for a little answer... In this case, for a better understanding why i typed these in, was... Best cable i could chance, for a better connection, was the 3M - 3302-40 - RIBBON CABLE, 40WAY, 30.5M (with PVC Polyvinyl chloride Jacket) (non drilled) (Farnell Order Code: 8608636) for the 3M - 2010-40 - RIBBON CABLE, 40WAY, 30.5M (with Polyolefin Jacket) (drilled) (Farnell Order Code: 4140679) with same length. I think, the Insolation of the cable, was the point. I had to connect Encoder to the DIN Boards with a minimum length between 25-30 cm. The signal with the standard "tinned" cable was so terrible, and bad for sure when i touched it. The notes are spinning around...... I soldered the Encoder with the "Rainbow Drilled" Cable, and the same length and finish. Good events and a stable connection, with the same length. There was not only the cable length the problem, only the Material.. "but it had to do with the length! :whistle: " For the Board connections, i found these insolated ribbon cable. 3M - 3517-40 - RIBBON CABLE, 40WAY, PER M (PVC Polyvinyl Chloride Jacket) (Farnell Order Code: 8608636)

I don´t have precalculated my project yet. It took around 6 months to build this without the Case and Buttons with LEDs. If you are interested, can i build a thread for my project, so you can see the facts. It is a 16 Channel Controller, inspired by Ableton and Traktor to build this. It has 16 Channels with, 1 Fader (60mm) ALPS, and 7 Analog Pots ALPS (10kOhm with center detend) per channel in Vertical direction. 32 Soft Touch Buttons (non clicker) per channel and 5 Encoder per 2 Channels. 5 Buttons per Channel would be the BLM Matrix / Looper Control or with a good finish App a 5x16 Step Sequencer. All ther part are from ALPS ! Now it is, to test it, build on a 1000x500mm Plate to test all options before i build it in a case. It is not good to write down the project without pictures, so IF you want, i thread it down, in this forum..... "In this case, the option to buy, is based on the words from the Master, T.K. ... I am not trying to earn money with building this great Stuff. This is the first project, and the second would come, i knew." Greets Chris

A double Twitch?! NOT BAD...... Not really! Here are still some harder projects. about the Parts. I´m not involved, with the LPC technical device. I can tell you, that 128 analog Pot´s,40 Encoder and 512 Buttons are still possible to integrade with the STM32 Core Board without LPC Module. In the repository, is a quickie program, with the name csc. This available to build a console with 2x 16x16 Button Matrix Scan (512 Buttons), 4x AINX4 Boards (128Pots), 40x LED Rings and also 40 Encoders. I hope it helps you...

Specific electrical resistance, electrical conductivity, Conductor resistance Spezifischer elektrischer Widerstand, elektrische Leitfähigkeit, Leiterwiderstand nach vielen Fragen, bezüglich der Kabellänge versuche ich mal mit folgendem zu helfen. After many questions regarding the length I try to help with the following Das Bespiel gibt den Widerstand eines 100 meter langen Kupferkabels mit 1,5mm² Querschnitt an. The example section specifies the resistance of a 100 meter long copper cable 1, 5 mm² 100m , 1,5mm², Kupfer bei 20°C = 1,19 Ω 100m, 1,5 mm², Copper at 20ºc = 1,19 Ω I HOPE IT HELPS TO UNDERSTAND THE PROBLEM ! I hoffe das es hilft das Problem zu verstehen ! GREETS kabellänge.bmp

For this thinks, i had to display on the screen, are the technical features from the Core32 big enough. I will see, when the displays are playing...... (or not)

I found this in the forum: at Screenkeys When i calculate now. I see a rate more about 125kHz at 8 enable lines with the STM32 (4MHz). I need details. In the Datasheet i´ve read Correspond to high speed MPU bus interface - 2 MHz (when VCC = 5V) -External clock frequency (fcp) min.125kHz typ.250kHz max.350kHz -Clock oscillation frequency (fOSC) min.190kHz typ.270kHz max.350kHz and Relationship between Oscillation Frequency and Liquid Crystal Display Frame Frequency The liquid crystal display frame frequencies of Figure 22 apply only when the oscillation frequency is 270 kHz (one clock pulse of 3.7 ms). 1/8 duty cycle 1 frame = 3.7 μs * 400 (clocks) * 8 = 11850 μs = 11.9 ms Frame Frequency = 1/11,9ms = 84,3Hz I DON´T REALLY UNDERSTAND, WHAT THE PROBLEM IS..?! The Displays show only defined Values and Setups. They don´t display any Animated Graphics. Only 1 of the 8 or 16 CLCDs shows the actual TrackTime. When my C Programming scills are so good, i will let one of them act like a Anaylzer Display. Must be the Update frequence so high to drive them with the Enable line over a DOUT PIN? :question: I´m confused !! :question:

Also, Björk has one ! See... 48:25Min http://www.youtube.com/watch?v=GxJvbZsHNUY

Erging mir 1000%ig genauso ! Präsentier einfach mal deine Grundidee..... Viele hier kennen Details, die man als Anfänger, schnell mal kurz übersieht oder gar nicht kennt.

Thanks! The extra writing is not the point... I had quit Problems with the GLCDs (PCD8544). They are so "rubbish" and very bad to solder with that small Pads. After, light touching, the first solder pads torn down. Thats so rubbish!!! I will buy the good old CLCD Displays and build this in. That is a good, old school, choise. BUT BACK TO BASIC......... Can tell some more details? :question:? ! the refresh rate is only fast as the 595 (Multiplexer) can switch :question: For 595, is the switch time from pin to is around 20-25 ns When i have 8 Enable Lines for the Displays at DOUT Pins, the fastest / maximum Update Rate could be around 200 ns

Than is Core32 or LPC a Hattrick ! Sorry, but the small Traktor Control Surface is breakfast for this..

Some kind like that..... I don´t think that this a Midibox or an arduino is, but it could be a Midibox! :sorcerer:
