Re: Starting up... again... for the 3rd time, please, need h

I don't need all voices from the same SD Card/RAM, so I could use multiple 32 or 64 voices blocks with multiple sets of chips, etc ... I only need 4 point hermite interpolation, which is kind of a simple code, or at least linear interpolation. In any event, I may start up with a simpler project firs...

Re: Starting up... again... for the 3rd time, please, need h

Thanks. And yes, the import tax sucks... Ok, I'm working on 2 projects actually. One require around 20 notes of polyphony, 16 will do, but they are stereo sounds, so I'm thinking 32 notes total. The other is BIG, 256 to 512 notes of polyphony, so we are using a computer instead for now. But would be...

Re: Starting up... again... for the 3rd time, please, need h

One detail, I'm thinking that we will need our own boards using multiple chips, to keep things easy to solder and also low-cost, so purchasing the boards from Xmos would be too expensive, considering that we need tons of polyphony, and I'm pretty sure one single chip won't do it. Unless working with...

Starting up... again... for the 3rd time, please, need help

Ok, guys, I'm finally giving it another go, for the 3rd time, as so far I had tons of problems and couldn't get much done, sadly. Now a local company needs my help, and I need to figure out if XMOS would do the trick. ;-) First, I need to know which chip is the easiest one to handle, so we can make ...

Re: Less new projects?

2) Hardware - Ok its time to build my 1st Xmos board lets look at the obstacles thrown in my newbie path: Packages, damm it nothing through hole only surface mount bugger OK smd it will have to be. What are the packages ? G4 BGA ouch not a cats chance of me doing that, L2 WTF double row QFN and min...

Re: XArduino

<r>Well, someone asked why the Arduino -> I'm an Arduino user, and I must say, there are things, to my brain, that are just easier to do on the Arduino. Also, the Arduino has hardware UART which for MIDI working, makes more sense, so we don't just lose a 100Mhz Thread just to check for MIDI signal. ...

Re: Starting up... again... how to program blank chips?

Slowly the people on the Arduino Forum is starting to like the idea of a XMOS Shield for the Arduino. :mrgreen:

Re: Starting up... again... how to program blank chips?

BTW: could somehow help me out and point me to a 16-bit DAC I could find on eBay that would be OK/GOOD and also work with the XMOS chip? :oops: Don't bother about other distributors, as I'm in Brazil, and right now I'm only getting things on eBay as its easier and has low-shipping options. Thanks. Wk

Re: 12 Bit PWM Sound Output and Math all in one Thread

Thanks for all that input, but that doesn't help me at all, sorry. I know all that, but I need to fix the code so it works, simple as that. ;-) The other methods are just too complicated for such a silly thing. I did some great PWM audio on the BeatVox project with a small AVR, so I'm sure I can com...

Re: Starting up... again... how to program blank chips?

Ok, here's the Arduino MEGA2560, which has 256 KB of flash space. Enough for anything, and it has all the power requirements besides the 1V regulator. (unless the current draw of any of the 5V/3V3 regulators are not enought) To talk to the Arduino during real-time mode, 8-bit parallel communication ...
