Weekly Updates
Here you'll find regular progress updates on the project.
Week 7
finalized project idea & proposal
ordered extra ultrasonic sensor
picked up aux input speaker
did some research on getting audio out of the board
Week 8
got all the parts!
started on the code
figured out a more detailed plan of which pins will be used for what functions, etc.
haven't got audio working quite yet but hopefully will over the weekend to stay on track
Week 9
finally got sound out of the board!
currently just a sine wave with weird beeps, I'm going to try using DMA to smooth it out
slightly behind the timeline but not terribly so
Week 10
now using DMA to fill the I2S buffer
fixed the sine wave somewhat (getting a resolution of 2Hz now, good enough for the higher registers)
volume control is pretty smooth
got two ultrasonic sensors working simultaneously
Finals Week
finished !!!!!!!!!
no LCD unfortunately but added button and on-board screen functionality
you can choose a scale to play on
