3 Intro The Midi Glove has the following features: –Allows a user to specify key and scale they wish to play in –Translate your finger positions in space –Convert these into musical notes played by the Z80 trainer

4 Challenges Create a glove that sends out signals based on finger position Understanding and Implementing the UART Triangulate position of glove Translate X,Y,Z position and finger position into MIDI signals. Deal with a feedback problem given off by the Z80 Getting all the parts sent to the right address Using third-party hardware (glove, MIDI keyboard, …) can create problems more than anticipated

5 Software Flow Chart Z80 computes user’s hand location and finger state Send to Midi Device From UART Finger Position From UART Finger Position Obtain user defined variables Generate MIDI Code

8 What We Learned Integrating hardware is more complicated than it may seem especially when a Z80 is involved Leave plenty of time for unexpected set backs UPS and FedEX have trouble finding Lerner Hall Learned Valuable design, debugging, and problem solving skills

9 Conclusion Using microprocessors in a project is pretty challenging but at the same time important in providing flexibility. Designing of generic code allowed us for a quick and robust integration. A more reliable micro trainer would have facilitated a smother and less error prone integration of our hardware components. Thanks to all those who helped out on our project.
