Is it Possible to get more juice to my backlight for my lcd. Adjusting the pots only make things darker :'(

LOL ok that clears things up. Thanks, Jeffry

Thanks for the tip i will look for the documntation on the main.asm. All sid's WORK woohooo. Thank you everyone. Time to wrap things up. Only 1 question remains. If i wish to use the sid player app how do i load songs? Does it mess up the main sid program? thanks

Well i am trying to get the last 3 sids to work. I do seem to have a problem. I click link button. I upload mios modded to 0X01 and after that i upload sid slave 1 link button is still on No reboot after upload. The slave does not work? Am i doing something wrong? Is there a other way to get software on? EDIT* i just used the code to open the link and then uploaded! Now sid 2 works :P. But let sid 2 play link button must be enabled is this right?

Thanks for the tip Dave. I use the standard 470 If i don't like it i will tweak it. Well now to put in the three other sid's i only have the 6581 but i hardly have noise. Maybe i have my system not loud enoug. The only thing that needed to be done were switching buttons and led's + - . So i made alot of mistakes. I only find that my lcd display is flickering on occassions. And the sync led is very weak but not when i add normal power to it. p.s. the sid has a huge tweak factor in sound i luv it :)

YAY It was indeed a short! Now the unit works. Well asside from some more little faults i have made. Like led's etc. Dave and Thorsten thank you for helping me out finding the HUMAN bug :):):). I will post if i find more things i cannot figure out. thx again

Hi Dave, I have tested. All buttons give 5,14V on pull up. All rotary encoders give values that go to 4,something the voltage varies when i twist a knob. I soldered in the links but i still have the same issue only when i press button 1 of J3 i get diffrent display. Nothing happens on lcd when i twist or press rotary or buttons. ??? ??? ??? Cheers, Jef

Well my dutch is to cry for as well ;) Mike's I have not all links. I will add them. Can you explain this a bit more in detail? Do you mean that every 10K resistor must have a voltage of 5V Cheers, Jef

Hi Dave, No i have phrased my story wrong. I have 9 chips only the rest of the pcb is not stuffed (the last three that are available) i have 3 din pcbs. 2 Fully stuffed and the last one only 1 chip. Jef

Hi Dave, I connected J1 of DIN to J9 of Core Pin 8 and 16 on all chips is 5.13V of the DIN When i stuff all chips and power on synth then only the 1 st button of the DIN works (i followed the schematic and this is selection button 1 on J3) Is it because my last DIN is not fully build? I only wired the 1st chip. Cheers, Jeffry p.s. Thanks Mark420 for your kind words ;)

IC1:Vcc(25) - IC1:Vss(14) = 5.18V IC2:Vdd(16) - IC2:Vss(8) = 5.18V IC3:Vdd(16) - IC3:Vss(8) = 5.18V Ok i have just tested the notes thing i hope this is not really nbecesarry but if so i will do the test Yes i hear notes Both of you thanks! So what is the next step? Connect the control panel? First leds than buttons or should i do both?

I have a nice ready screen on my LCD (this is the third lcd the other two seem broke) What is the next step? Do i load setup_6581_with_cs.syx or do i load main.syx Or must i solder the control panel wiring first. Or shoud i stuff the SID before applying the sid files? TIA

I have changed the battery of the multimeter. And rechecked voltages. I have changed values in the post above! What should i do now? I have burned the pic with the bootstrap loader v1.1B

I have a el cheapo multimeter. The battery seems dead almost. I am gonna try it again tomorrow with new battery! Pac_c thanks for cheering me up. I will have a good night rest now :D

I removed all chips. It's 5.17V It's 12.01V It's 14.11V 1. 12.05V 2. 8.93V 3. 9.5VAC The PSU is from a C64 I i have tried two of them. Both of the PSU same results. Cheers, Jeffry

Hello all, Thank you so much for taking effort in trying to help me out. I have had a lot of sid problems since the control unit didn't work. So i wish to start from the beginning. First issue! My optimized psu is not giving the right voltages! I get 6.13V on the +5 and 11.06V on the 14VDC connected to ground of the power-led What can be broke the regulator?

Ok i am fed up with it. Who wants too look at my quad sid. I will pay for all inexpenses. If not then i will sell the unit. I have tried everything and despite the help i have recieved nothing helps. I am blaming myself let that be clear. Anyway pm me if you want to have a look at it.

PLease help. Still only the control 1 button is working.

CS is enabled (the lcd says it in a flash) the asm file is ok. All voltages of din and dout are ok. Any more options please :(

pay_c i do not really understand what you mean. I have loaded bootstrap with JDM 1. Installed Mios_v1.7 2. Installed SID_V1.6_with_cs How do i enable the control surface? I have not used a seq app yet.

Hello, I am testing my quad sid but after mios and sid_cs upload i get a normal display. Now no led burns and the only button that works is the control 1 button. It chages the display. no rotary no led no button works ???? What have i done wrong?

Je kunt ons altijd vragen! Success met bouwen alvast!

Nee ;D NorthernLightX en ik zijn bezig. Ikzelf ben bijna klaar.
