Sorry for my slow reply! Yessir, that's the one and it's about 100 bucks. Programming with the Spin is half straight forward, half alien language. To be really good at it is to be really good at complicated math, but it's the same as analog electronics in that you can work with the parts without knowing exactly how they work, knowwhatimean? I know how to hook up an op-amp to do a few different things but I couldn't grab a bag of transistors and diodes and build one from scratch. The Spin is like that.. especially if you're good at learning backwards from examples.. between the knowledge base online, the forum, and all the sample code that Spin provides, you get shown how to do nearly everything in some way and you sort of have to figure out how to put it together from there. You get to mess with 1s and 0s tooJero wrote: This the one?...http://spinsemi.com/products.html
How involved/difficult is the programming or coming up with patches? Is it an alien language of zeros and ones or a little more straight forward than that?
Code: Select all
;Variable LPF
equ lp_filt reg0
equ kfilt reg1
;Set up Pot2 for filter control
rdax Pot2,0.99 ;read in Pot2, limit value to set maximum shelf
sof -1,0.999 ;invert rotation, knob up = filter up/more treble cut
wrax kfilt,0 ;save filter coefficient control
;Set up input, do filter, then output
rdax adcl, 1 ;read in left adc
rdax lp_filt,-1.0 ;read in filter register
mulx kfilt ;multiply by filter coefficient
rdax lp_filt,1.0 ;read in filter register
wrax dacl,0 ;write to left dacnicccccceRyan wrote:This is all percolating nicely behind the scenes, guys, and I think we'll be on track for December questing for sure!
Hopefully the etch looks close to this! Clean and simple!Ryan wrote:Good idea, Ian, the BQ would be a perfect tool for that with all the right controls to make any effect. Like a digital Inventobox! *smile*
This week I made the first BitQuest in real life, the first proto is borned and it works perfectly!
Here's the layout image:
I don't know exactly what we'll do for the finish or knobs, this is just for fun, but I could see it having the jewel.. jewels really suit an adventure quest in my opinion. And I just added the labels in Picasa but that's how the controls will go.
Side shot for jacks.. the expression jack will take over for digital control 1 letting you run the cool parameter of every patch with your foot. (filter freq, notch freq, pitch, delay time, sample rate, reverb decay, one cool control for each patch)
Kind of a tough build but that's part of the fun of the adventure!
So the box and pcb are pretty much sorted... now I just need another weekend or three to finish the code!
