JoyLabz is looking for a computer engineer to transition Arduino code written for the ATmega32u4 to an cheaper, shorter lead time microcontroller. This is essentially a re-engineering of the Makey Makey (makeymakey.com) circuit board to a new MCU.
Select a new chip meeting the technical and business requirements for the project (5V, 20 to 22 digital i/o, USB HID, comparable power) such as Silicon Labs C8051F38x or Cypress CY8C32.
The chip should be widely available and cost less than ATMega32u4 in bulk. The chip should have built in USB HID support and the vendor should allow registration of a PID under their VID.
Reimplement the existing Arduino C code (approx 750 lines) on the new MCU. This will include implementation of some Arduino libraries (see code link) if necessary.
Add one new feature for key remapping (it’s a hack!) (estimated 200 lines code)
The eligible candidate should be an expert with writing software on 8-bit MCUs in Arduino and C.
Show previous experience with writing on the selected platform or similar capability.
Timeline goal is 1 month. Please submit a resume or website detailing your experience with similar projects and your rate for consideration.
