I was wondering if there's a possibility that a variant of the RCD firmware/hex is floating around that might do even longer divisions.
Now I have an RCD and an SCM, I'd really like a super RCD that I could use for triggering x1, x4, x8, x12, x16, x20, x24, x28, x32 etc for triggering bar length progressions.
I do understand I could just clock the x4 out of my rcd into another rcd, but figured I'd ask if a specific version might exist. |

| isn't this what the RCD breakout panel is for? goes down to x64 if i remember correctly. it's very cheap, you can even buy a kit (i haven't built mine yet...) |

If you have the avrisp then grab code from the 4ms site here.
| Quote: |
if (switchread==0) {
t=7;
d=adc>>5;} //LL: d=0..7, masked by t=0b00000111 gives on jack 1 DIV 1-8
else if (switchread==(1<<ROTATE_JUMPER2)) {
t=15;
d=(adc>>4)+8;} //LH: d=8..23, masked by t=0b00001111 gives: DIV 9-16|1-8
else if (switchread==(1<<ROTATE_JUMPER1)) {
t=31;
d=(adc>>3)+16;} //HL: d=16..47, masked by t=0b00011111 gives: DIV 17-32|1-16
else {
t=63;
d=(adc>>3)+32;} //HH: d=31..95, masked by t=0b00111111 gives: DIV 32-64|1-31
|
Those are the jumper settings - so the t= in the various ones is the top division for that jumper setting ( minus 1 - in the code generally look at the outs and divisions starting at '0'). You'll want to up that t= value to the top division you're wanting for whichever switch setting.
The various gate and jumper sections have parts that look like:
| Quote: | if (GATEMODE_JUMPER){
if (o0==((((0+d)&t)/2)+1)){OFF(OUT_PORT1,0);}
if (o1==((((1+d)&t)/2)+1)){OFF(OUT_PORT1,1);}
if (o2==((((2+d)&t)/2)+1)){OFF(OUT_PORT1,2);}
if (o3==((((3+d)&t)/2)+1)){OFF(OUT_PORT1,3);}
if (o4==((((4+d)&t)/2)+1)){OFF(OUT_PORT1,4);}
if (o5==((((5+d)&t)/2)+1)){OFF(OUT_PORT1,5);}
if (o6==((((6+d)&t)/2)+1)){OFF(OUT_PORT2,7);}
if (o7==((((7+d)&t)/2)+1)){OFF(OUT_PORT2,6);}
} else {
if (++o0>((0+d)&t)){ o0=0;}
if (++o1>((1+d)&t)){ o1=0;}
if (++o2>((2+d)&t)){ o2=0;}
if (++o3>((3+d)&t)){ o3=0;}
if (++o4>((4+d)&t)){ o4=0;}
if (++o5>((5+d)&t)){ o5=0;}
if (++o6>((6+d)&t)){ o6=0;}
if (++o7>((7+d)&t)){ o7=0;}
|
So could maybe change the upbeat one to:
if (++o0>((0+d)&t)){ o0=0;}
if (++o1>((3+d)&t)){ o1=0;}
if (++o2>((7+d)&t)){ o2=0;}
if (++o3>((11+d)&t)){ o3=0;}
if (++o4>((15+d)&t)){ o4=0;}
if (++o5>((19+d)&t)){ o5=0;}
if (++o6>((23+d)&t)){ o6=0;}
if (++o7>((27+d)&t)){ o7=0;}
or something like that - poke with it.

I need to buy a burner and look into this some more.
Although my worry is I'll get carried away and before I know it I'll have 12u full of RCD's all going crazy. |

bmsith - have you actually had this working with your code tweak? Has anyone? |
when i said bsmith was a wizard he is. 
you should hang out on IRC and talk to him about it.

Yeah, I've changed what the jack divisions put out, as well as some other things like changing some jacks to rotate in increments of 2 while others do 1 as shipped...
there may or may not be some much cooler stuff on the rcd being worked on by bigger brains than myself we can all look forward to.

Get a second RCD, and send the slowest clock from the first to the second....  |

| AVR programmer ordered, 3rd RCD/SCm kit ordered. :-) I'm keeping this third one for bonkers. |

I can see the RCD project files:
http://4mspedals.com/clocker/code/rcd_avrgcc_project.zip
But does anyone know if the other hex files are available as project bundles? I'd love to see how the sequential switch and the SCM are coded, to get some foundation for how to approach some of my ideas.
I was also thinking of putting some of the project files up on github, so they can be versioned, and forked and bug fixed communially.
Hoping Dann, might wander in here and say everything would be cool with that  |

Yes! I haven't used github, but it looks allright. If you want to set up a clocker repository, I'll put the various versions I have around on it. It makes a lot of sense to use a revisioning system because there are several forks already, and I'm working on some new ones too...
Here's the SCM project files:
http://www.4mspedals.com/scm.php#firmware
I've got the Tracking Gate Sequencer code as well, I can throw that up too.
And I know I need to comment better  Please feel free to ask me questions/explanations of the code.. |

What fork!? I thought it was a spoon? 
The only thing that makes any sense to me in this thread is "a second RCD"

Heh... OK with thedug's help I dove into github... started a repository here:
https://github.com/4ms/Clocker
Maybe we should move this discussion to the DIY forum? |

This is awesome. Just bought an RCD because of this thread. I want to try programming something more radical with it though 
I had a quick look at the code (and there is actually a lot of comments - very helpful  ) so if I understand correctly RCD (or SCM) can be seen as 2 CV inputs going through ADC, and same ADC converts additional CV inputs in the extensions?

Awesome ! This is going to be an adventure.
As I suspected SCM is much more complex than the RCD by a factor of pw0=8400,pw1=4200,pw2=2800,pw3=2200,pw4=1680,pw5=1400,pw7=1050; |
