Kroutshev sammichSID *FIXED*

[kroutshev]

Hi,

i've finished to solder everything, i have tested all voltage and now it's time to connect it to my computer to upload soft !! When i power on sammichSID i've got the line from Mios 1.9g and after i try to test my lcd and nothing ! Midi in doesn't work :-( !! Midi out is good.

I have checked voltage on IC2 (6N138) and i've got these voltage :

Pin1 = 0-----Pin5 = 0

Pin2 = 0-----Pin6 = 5 ????

Pin3 = 0-----Pin7 = 0

Pin4 = 0-----Pin8 = 5

I have checked soldering and everything seems to be correct.

What i have to test to resolve my problem ?

Thanks.

If that's supposed to be a top-down view of your 6N138 you're counting the pins wrong.

1   8

2   7

3   6

4   5[/code]


I am not quite sure I understand your post, so to clarify: 


- You do get the upload request in MIOS Studio?

- Your midi cables are connected correctly and working?

- The routing in MIOS Studio is correct for both the IN and the OUT?

Hi Nils,

To explain more precisly i'm on 7. Initial Testing and Firmware Upload step

My midi out is working well but when i test my lcd with mios studio the word that i have written into "MIos lcd message" window doesn't display on my sammich Lcd.

yep you're right about pins counting i was too tired last night !!

Pin1 = 0-----Pin8 = 5

Pin2 = 0-----Pin7 = 0

Pin3 = 0-----Pin6 = 5

Pin4 = 0-----Pin5 = 0

- You do get the upload request in MIOS Studio?

Yes

- Your midi cables are connected correctly and working?

Yes

- The routing in MIOS Studio is correct for both the IN and the OUT?

i suppose ! i have used first my sound card and after thru an elektron TM1

Same thing with both.

I can send screen shot of mios studio midi device window that evening.

Thanks for your interest.

Mine has 5V on pin 6 also.

Is the shunt in JMI on the left?

Is the shunt in JMI on the left?

Yes, like white mark on pcb

[Wilba]

Did you check the solder joints on header JMI?

[kroutshev]

Ok Wilba, thanks a lot it seems that it was a bad solder on JMI !! Now midi in is working :-) !

I have uploaded the file that you have joined into your mail, i have formatted bankstick ! Everything seems to be ok but when i install 6582 into their sockets when i power on, lcd is lightning but nothing is displayed ... Only light !! I have checked voltage into pin 14 and 28 and i have measured 8.93 V and not exactly 9V as you describe into your building guide !! Is it a problem ?

Why nothing appeared when i have sid's inside ?

Thanks for your precious help !

[kroutshev]

Yes !! i have resolved all my problems !! The last one was due to voltage of power suply, i've have increased the voltage and now sammichSID is completly functionnal !!!

Now it's time to understand it and make some sound !!

[Wilba]

Good to hear it is all working now! :)

[kroutshev]

Yep thanks, very good concept for future gig cause of his little size but big sound. I'm sure that sammichSID will be friend with my MachineDrum !!

It seems to be a good combo !

[Wilba]

Post a photo next to Machine Drum.

This would be a good tease for the Elektron forum :P

I'm sure that sammichSID will be friend with my MachineDrum !!

[kroutshev]

This would be a good tease for the Elektron forum :P

Awesome paint job and nice mods...

Tell me about the paint... that is so much better than the stuff I use, I love that gloss.

[kroutshev]
