Hi,

I found the some mistakes and the some differencies in the names of some functions if comparing pdfs with the .asm file, too.

You are able to measure and compare similar schematic parts of the CS board with your multimeter too ( in the beep mode, diode measuring mode without powering CS board).

Hi kogz23,

Nice work !

What you are thinking about :

DIN_ENTRY CS_MENU_BUTTON_Exec , 16+5 , 3

function

Are you trying to use it too ?

The building my own CS is my next step too .

Hi,

From the Wiki pages

"Control Surface Wiring

These describe the wiring of the control surface PCB. They can be used as a guide for constructing your own control surface. You can freely assign LEDs and switches to the matrix, but for the best performance in the firmware, the Modulation Matrix LEDs should be wired with common cathodes in vertical columns, so that the LED matrix will illuminate one column of 8 LEDs each shift register update.

LEDs and switches marked with an asterisk (*) are V2-specific features or just things I added for my own use. Refer to http://www.ucapps.de..._manual_fp.html for more information.

BTW I just noticed my CS DOUT wiring PDF is wrongâ€¦ â€œLFO Sinâ€ and â€œLFO Triâ€ are swapped and â€œSyncâ€, â€œCCâ€, â€œEditâ€, â€œPlayâ€ are in the wrong order (should be â€œPlayâ€, â€œEditâ€, â€œCCâ€, â€œSyncâ€)

EDIT 2 - The menu button should be at the intersection of â€œJD8-D3 & JD5-D3â€ NOT â€œJD8-D3 & JD5-D4â€

http://www.midibox.o...dout_wiring.pdf

http://www.midibox.o..._din_wiring.pdf

The rotary encoders are connected directly to the first four DIN modules on the base PCB (i.e. JD1 to JD4) as per the normal way of connecting rotary encoders to DIN modules. Just like the LEDs and switches, you can assign them to any pins of DIN modules and configure this in the table in the .asm file.

Hi,

I have completed my MB6582 Base PCB and I did some voltage checks (I went for option B, the original C64 power supply). I haven't installed any IC's so far !

What you can not see on the first picture are the following checks:

J3 (5V) -> 5,33 V
J25 (9-11V) -> 14,28 V -> is this still ok ?
C12 (9V) -> 8,97 V

I made a mistake in the beginning when I checked J25. Unfortunately I slipped off with the contact and created a short on J25 (for a very short moment). After this I check all the points above with the result:

5 V check points -> 5,33 V
9 V check points -> 8,98 V (regarding the SID's: depending on the jumper - I have tested both positions, 9V and 12V)
12 V check points -> 11,82 V (regarding the SID's: depending on the jumper - I have tested both positions, 9V and 12V)

I wonder if I have damaged the two big capacitors close to the voltage regulators ? I mean the measurements look quite ok, apart from the J25 which has 14,28 instead of 11 V. Do you think I can carry on with the board, or do I need to exchange the capacitors or the voltage regulators ?

Your advise is much appreciated !

Cheers

Hi,

14,28V on J25 pins instead of 11 V is ok ! This voltage is formed from : Your PSU ~9V out - bridge rectifier - filter electrolytic capacitor - voltage on J25

The other voltages look right, too.

Janis

Hi,

Finally I made my power supply like the C64 power supply with the 2 output voltages. The +5 VDC part is realised as in the picture "5V,7,5A Regulator" with the SD1084 chip (the similar chip by another manufacturer) in TO220 case .

There are the 5 amp diode bridge and the 4700uF capacitor in my schematic input part, too.

I used the case from an old PC 200W power supply.

The MB6582 is powered like the http://www.ucapps.de...u_optimized.pdf - "PSU option B".

Janis

first I wired up the 8, then only 4 and D0-D3 from the LCD to ground and D0-03 from CORE open. The strange thing is it doesn't get stuck when I move the data dial, but when I use the selection matrix or the v-pots it gets stuck after 3 seconds ... I don't understand why, please any help? Thank you for your reply.

Wiring Diagram: mbhp_lcd_mios8.pdf

If a PIC18F4685 is used in the project (-> MIDIbox SID V2), the LCD is accessed in 4bit mode. Accordingly, the data pins D0/D1/D2 and D3 should be left open at core and LCD side (don't connect them to ground!) - see mbhp_lcd_4bit_mios8.pdf

Happy birthday Wilba !

The best wishes !

edit:
i'm talking about the sidV2 firmware, latest revison (.37), and it has worked fine before.

Hi Roger ,

May be I am wrong. My midibox source files are on the another PC .

I remember. When I connected 4x20 LCD to the sidV2 with setup_6581.asm (setup_6581.hex) I had problems with the displaying all 4 lines. Then I changed this part :


;; LCD line -> cursor offsets

#define DEFAULT_LCD_LINE_Y0 0x00

#define DEFAULT_LCD_LINE_Y1 0x40

#define DEFAULT_LCD_LINE_Y2 0x14

#define DEFAULT_LCD_LINE_Y3 0x54

with the similar part from the setup_6582.asm file


;; LCD line -> cursor offsets

#define DEFAULT_LCD_LINE_Y0 0x40

#define DEFAULT_LCD_LINE_Y1 0x14

#define DEFAULT_LCD_LINE_Y2 0x00

#define DEFAULT_LCD_LINE_Y3 0x54

It helps for my setup.

Janis

Hi,

I never built any clockbox. But when I building my MB808 , I reading more about bpm digits.

In the main.h file after this

// define the dout register which should be used to display the status of

// the 8 outputs (which clocks are running)

// 0: disabled

// 1..16: DOUT shift register 1..16

#define MULTI_CLOCK_STATUS_DOUT_SR 1

you need to define the additional DOUT SRs like this

#define DEFAULT_BPM_DIGITS_ENABLED ... ;; 1 or 2 depending which type of the 7 segment displays you have

#define DEFAULT_BPM_DIGITS_SEGMENTS 2 ;; SR 2 for the displays segments pins

#define DEFAULT_BPM_DIGITS_COMMON 3 ;; SR 3 for the displays common pins

Sorry , I do not know more.

Janis

Yes. You wouldn't need nav buttons for the LCD under displayed menu text .

Hi,

In the MIDIBOX FM user manual you can read comment to the front panel functions :

... "The huge number of parameters restricts the flexibility in possible configurations. E.g., the use of a 2x40 LCD is strongly recommended so that the patch names of all instruments are visible on the main screen. In some submenus the parameters are arranged in a way which makes a quick access to relevant values only possible if eight values are visible (and selectable via soft-buttons) at once - example: the EG5 envelope page with the parameters Attack - AttackLevel - Decay1 - DecayLevel - Decay2 - Sustain - Release - Curve -..." in the leftmost view, and all depths in the rightmost view of the page. With a 2x16 display only three menu entries are visible, with a 2x20 display only four. "...

Hi

About resistor networks right orientation you can read in the point 12 :

These are 5 or 6 pin common bus resistor networks, in which one pin is â€œcommonâ€ and is connected to all the other pins via resistors. The dot indicates pin 1 (the common pin), which goes in the square pad (left-side) directly above/below the component identifier (eg. â€œR31â€). Do not get a 6-pin resistor network which is three isolated resistors connected to three pairs of pins. The correct one is Mouser part 264-10K-RC. If buying elsewhere, I believe if given a choice between parts with an â€œAâ€ or â€œBâ€, the â€œAâ€ means â€œcommon busâ€ and â€œBâ€ means â€œisolatedâ€. (See here: http://au.mouser.com/catalog/636/619.pdf)

From the MB6582 parts list :

http://www.midibox.org/dokuwiki/doku.php?id=wilba_mb_6582_parts_list

It's easy to check the resistor network's common pin orientation with the multimeter , too . In the 20Kohm measuring scale.

" 100kohm work fine, 500kohm will also work... the value just specifies the max feedback "dampening" which is at maximum for 100kohms already."

Hi Thorsten,

1. I made some changes in code for the pic18f4685 for the 4 x OP and 4 x INS buttons. These buttons look like working right now. But I don't know how correct are the code changes total(y).

the code part from the cs_menu_buttons.inc :

before:

;; CS_MENU_BUTTON_InsOP1

;; movlw 0

;; rgoto CS_MENU_BUTTON_InsOP_Cont

;; CS_MENU_BUTTON_InsOP2

;; movlw 1

;; rgoto CS_MENU_BUTTON_InsOP_Cont

;; CS_MENU_BUTTON_InsOP3

;; movlw 2

;; rgoto CS_MENU_BUTTON_InsOP_Cont

;; CS_MENU_BUTTON_InsOP4

;; movlw 3

;; rgoto CS_MENU_BUTTON_InsOP_Cont

changed to :

CS_MENU_BUTTON_Ins1

bcf CS_MENU_MODE, CS_MENU_MODE_INS_OP

movlw 0
