Maybe this article will help you : http://www.ask.com/bar?q=Capacitor+Explanation&page=1&qsrc=6&ab=0&u=http%3A%2F%2Fwww.uoguelph.ca%2F%7Eantoon%2Fgadgets%2Fcaps%2Fcaps.html

I could be wrong. I don't use com port connection. If you have right Yamaha driver. In Mios Studio/MIDI/MIDI Devices push "Rescan devices" and "you see" your midi core. After : Options/Midi device rooting and forward . Regards, Janis

Read ( 2 ) under drawing .

If you have +5V supply, you don't need any voltage stabilizer circuit. Because shorted circuit In with Out. In these stabilizers voltage drops~2,5volts, and they working with higher voltage ~+7,5volts to~+35volts. Regards, Janis

Hi! For panel mounting you need search push button switches. Only as an example : http://yqyiwei.en.alibaba.com/search/product?IndexArea=product_en&SearchText=Push Button Switch Regards, Janis

Are your 8 encoders with right pinout connected to DINx4 SR input pins i0-i7 as in example file for 16 encoders ? Is external cable right wired : Vs to Vs, Vd to Vd, S1 to S1, SC to SC, RC to RC to the correct Core port (reading commentary to schematic, too) ? mbhp_dinx4_16enc.pdf mbhp_dinx4_16enc.pdf

I could be wrong. When you tried both J9 and J6 with J1 DINx4, are you seen some differences in pinouts ( mirror ) ? From left to right side on core for J6 : RC SC S1 Vd Vs for J9 : Vs Vd S1 SC RC Regards, Janis

I could be wrong, but in setup file for MB64E for faders you only need define quantity = 16 and enabled mux = 1 : #define DEFAULT_NUMBER_AIN 16 #define DEFAULT_ENABLE_AIN_MUX 1 Regards, Janis

If you have 8 encoders hooked up, you need 2 SR for example: connect to all pins of J3,J4,J5,J6. I made some little changes in source file code . DIN module you need to try to J9 of core. setup_midibox16e.asm setup_midibox16e.hex setup_midibox16e.asm setup_midibox16e.hex

1. All encoders are not the same pinout. From wiki: http://www.avishowtech.com/mbhp/images/encspecs17.gif http://www.voti.nl/docs/rotary-encoder.jpg 2. As I understand : with old Pic16f877 core DIN module(s) is connected to J6 , but with pic18f...core is connected to J9 . Regards, Janis

1. Simple, helpful midi signal tester : http://www.epanorama.net/circuits/miditest.html 2. One of my midi cables I made from old PC keyboard cable with original DIN plug on one end.

Is your external wirings is correct, too ? http://www.tec.sci.fi/tecref/midiport.gif

Some info for similar, maybe, product : CM24064-1 from the same manufacturer. CM24064-1.pdf CM24064-1.pdf

I am happy, thanks for answers, Thorsten ! 1. Could you please attach your modified .asm file to this article? This should give me a complete overview. Attaching both, but problems to this moment with MIDIbox64 .asm file 2. It's in the Wiki: http://www.midibox.org/dokuwiki/doku.php?id=home:mbhp:module:din_dout_pin_list Thank you for this link, too. But for the first shift register, which interesting much more, in the pin hex number colon found only zero values. When read hex values for another shift registers, understand and made changes in Midibox64 (e) asm files. And Rx and Tx leds lights. Regards. setup_midibox64.asm setup_midibox16e.asm setup_midibox64.asm setup_midibox16e.asm

Hi. Thanks Thorsten for your great site ! ! ! How there are recomended ,read, read , but any way I have some questions. I have self-maded Pic based core, DIN Module, DOUT Module pcboards, some detented encoders from Alps , buttons, LCD 2*16 , 8 pots connected on J5 without mux . 1. Connecting datawheel encoder as recomended to SR#1 pins 4 and 5, made some changes in setup_...asm file (for datawheel put "1" instead of "-1"), compiling, uploading . See noncorrect Datawheel function, output module leds switching on off, too, when turn knob . It's looks like don't correct defined encoder. In mios_tables.inc changing detent to detent2 without any success,too. When made similar changes in MIDIbox64e setup_...asm for conecting datawheel and second encoder as for low cost solution, result was given correct and both encoders works fine without any flashing leds. 2. Have another question from the source file : ; For MIDI activity monitor: define the DOUT pins for the Rx and Tx LED #define DEFAULT_MIDI_MONITOR_ENABLED 1 ; if 1, the Tx/Rx LEDs are enabled #define DEFAULT_MIDI_RX_LED 0x40 ; DOUT SR#9, pin D0 #define DEFAULT_MIDI_TX_LED 0x41 ; DOUT SR#9, pin D1 If I want used only 1*DOUT Module with SR#1-4, where can find address table for and custom define the DOUT pins for the Rx and Tx LED? Thanks.
