We're currently looking to outsource the final stages of our prototype development and are hoping you might be able to help. We're developing a MIDI controller and are looking to have the circuit design and software finalised.
As a company we've been working on our design for a few months now, though as none of us are electrical engineers we're now seeking further expertise. Most development so far has been completed using the Arduino platforms - both Leonardo and teensy. For the protoype we're happy to either continue down this road, or look in to something more complex - we've been advised that STM controllers may be suitable.
Could you let me know if this is something you're able to undertake? If so I will send across an NDA and can provide you with more in depth details of work completed and the desired final outcome.
