NEW MB SID problems

[igi]

Hi!

I almost finished my MB SID V2 with four SID's, four SWINSID's, coplete CS an two LC Aout.

So for so good, and my new beast working almost perfect.

But there is is a few problems.

- Led for LFO positive is not working (I turn it like SID L,SID R and meter mode witch is working)

- I use a non detent encoders (bourns PEC 11) and they work a little strange. It's very hard to

adjust precise data (E.G.for transpose), and sometimes value jump E.G.from 10 to 36 even if I turn

encoder very slowly,or value is decrease for a moment even I turn un the right.

For the menu I used same, but detent encoder (mode 3) and works perfectly.

- C64 power supply is gets pretty hot. Is this normal?

Thanks everybody for support!

Hi,

how did you get -12V for the Aout_LCs out of the C64-PSU?

Either your encoders are quite bouncy, or there is something wrong on your DINs.

I'd check the dins for soldering errors first.

Have you tried changing the encodermode?

Hi!

I was modify Aout_LC to operate with single power supply and relace TL072 with LM358.

I need only 0 to 5V for controlling external CEM filters.

My DIN's it's OK (I check), because detent encoder is woking fine and all other buttons

works OK.I try all encoder modes, but other than non_detend is working even worse than

only one non_detent mode.

Best regards!

there is an application in the SVN to test the different modes of encoders

Hi!

Tkanks, but I'm totally lost in SVN.

What about LFO positive led?

Tkank you for yours support!

Are you sure, the LED works?

You can use a battery with a resistor in series to test it in the circuit,

but if you can, you should disconnect it from the Dout first.

Did you add

DOUT_ENTRY TMP5, 5, x, y ; LFO Positive LED

below "CS_MENU_DOUT_TABLE" in setup*.asm?

( with x=number of shiftregister and y=pin, e.g. 6,3)

HI!

The LED is works!

I try change "LFO positive" with "matrix mode" in the Dout

and led for LFO+ was working (but not matrix mode LED).

And yes, I add

DOUT_ENTRY TMP5, 5, x, y ; LFO Positive LED

in asm setup just like I did for SID L,R (with diferent x and y of course)LEDs witch is working fine.

What else can be wrong?

Thank you for your support!!!

When do you expect it to turn on?

Maybe you got that wrong? ;)

In the LFO menu you have to set the Waveform to PSn,PTr,PSw or PPl...

If this isn't the problem, i don't know what else to check.

Maybe someone with a working LFO+LED can chime in?

[igi]

HI!

I expect: when LFO goes in positive value (any waveform) then LED should turn on.

Or am I wrong?

I try all waveforms, PSn,PTr.. too, but nothing happend.

Thanks!

[Imp]

No, it just turns on, when you select one of those positive waves...or at least it should ;)

Without it, you can still see if you selected a positive wave, because then two of the LFO-Waveform-LEDs will be lit.

Have you checked, if the used SR/pin isn't already in use by another function?

[igi]

Hi!

SR is not already in use. When I set waveform to PSn,PTr,PSw or PPl, then RND led with selected Waveform is lit.

Here is my configuration:

DOUT_ENTRY TMP5, 0, 5, 6 ; LFO Sine LED

DOUT_ENTRY TMP5, 1, 5, 7 ; LFO Triangle LED

DOUT_ENTRY TMP5, 2, 6, 0 ; LFO Saw LED

DOUT_ENTRY TMP5, 3, 6, 1 ; LFO Pulse LED

DOUT_ENTRY TMP5, 4, 6, 2 ; LFO Random LED

DOUT_ENTRY TMP5, 5, 6, 3 ; LFO Positive

DOUT_ENTRY TMP4, 7, 6, 4 ; sid R

DOUT_ENTRY TMP4, 6, 6, 5 ; sid L

DOUT_ENTRY TMP2, 2, 6, 6 ; meter

DOUT_ENTRY TMP2, 3, 6, 7 ; matrix

Best regards!
