This board is bare-bones – you just get USB – but the development tools have been set up for you, and you can slap this on a breadboard and add your own additions (MIDI, audio I/O).
It’s a chewing gum-sized board with both a familiar ARM microcontroller and an FPGA. doppler: easier audio FPGAĭoppler takes that FPGA power, and combines it with the ease of working with environments like Arduino. Future modules could also make this easier. Wouldn’t it be great if instead of that abstract description, you could fire up the Arduino development environment, upload some cool audio code, and have it running on an FPGA?ĭoppler, on a breadboard connected to other stuff so it starts to get more musically useful. Now, all of what I’ve just said a little hard to envision. (Teenage Engineering was an early FPGA adopter see also the recent announcement of the Waldorf Kyra.) The challenge has always been configuring this hardware for use, which could easily scare off even some hardware developers.įor more on why open FPGA development is cool, here’s a (nerdy) slide deck: And we’ve even seen them used in some music gear. This works well for music and audio applications, because FPGAs do work in “close to the metal” high performance contexts. The upshot of this is, you get something that performs like dedicated, custom-designed hardware, but that can be configured on the fly – and with terrific real-time performance. You get all of that computational power at comparatively low cost, with the flexibility to adapt to a number of tasks. That’s kind of what an FPGA is – it’s a big bundle of programmable logic blocks and memory blocks.
The idea is irresistible: imagine a circuit that could be anything you want to be, rewired as easily as software. The FPGA is a powerful but rarified circuit. Tinkerers, developers, and people with a dangerous appetite for building things – read on.)īut first – why include an FPGA on a development board for music? (Now, end users, this may all go over your head but … rest assured the upshot for you should be, down the road, more cool toys to play with. If this appeals to you, we’ve even got a CDM-exclusive giveaway for inventors with ideas. It could be the basis of music controllers, effects, synths – anything you can make run on those chips. And the founder is so confident that could lead to new stuff, he’s making a “label” to help share your ideas.ĭoppler is a small, 39EUR development board packing both an ARM microcontroller and an FPGA. The new doppler board promises to meld the power of FPGA brains with microcontrollers and the accessibility of environments like Arduino.
