Recently I've found the time to start working on my synth again. Today I did some basic testing, and everything seems to be in order.
- Rotary encoders and push button inputs work.
- The DAC is responding to commands sent via SPI.
- MIDI data from my keyboard is readable via the UART.
I finally have the USB bootloader working too, so I can flash the MSP430 without any extra hardware.
Next step is to test out the LCD and start experimenting with sound output!
